How to Swab For Covid Test

Since the outbreak of novel coronavirus pneumonia, we must have experienced nucleic acid testing. Covid swab test Nucleic acid detection plays a very important role in the process of infection diagnosis of COVID-19. It can not only find asymptomatic patients in the incubation period as much as possible but also greatly reduce the risk of infection.

Nucleic acid detection is so important. Next, Dr Li will take you to have an in-depth understanding of the relevant principles of nucleic acid detection, the difference between mixed collection and single collection of nucleic acid detection, and the matters needing attention in nucleic acid detection, to help you better protect yourself while popularizing knowledge.

To understand nucleic acid detection, we must understand the detection principle. Let’s take a look at its detection principle first.

What is the principle of nucleic acid detection?

Nucleic acid, the genetic factor of the virus, is a macromolecular chain composed of four nucleotides. Different molecules represent different nucleotides and form a long chain. Nucleic acid detection is through the detection of nucleic acid in the chain, and this segment of nucleic acid is COVID-19 specific, other viruses do not.

The substance detected by the nucleic acid is the nucleic acid of the virus. At present, the detection technology is mainly through PCR (polymerase chain reaction) technology to detect the nucleic acid of the virus. During the detection, the nucleic acid chain of COVID-19 was used as the detection target, and the target gene sequence was amplified by PCR Test, which was combined with a fluorescent labelled probe added in the test reagent to produce a fluorescence signal.

The three forms of nucleic acid detection have their advantages.

Nasal swab test

This test method is to insert the test swab vertically into the nostril. And gently rotate the swab, stay in the nasal cavity for about 15 seconds, to test.

Compared with throat swabs, nasal swab testing is more accurate for inexperienced testing personnel. And the risk of exposure is lower. However, it is not suitable for some patients with nasal allergies, high blood pressure and people who take anticoagulation and antiplatelet for a long time.

Throat swab test

At present, the most widely used detection method is also a form that is often used by everyone. During the sampling process, the patient opened his mouth and made an “ah” sound, and the testing personnel used a sterilized cotton swab to gently and quickly wipe the pharyngeal lateral wall and posterior pharyngeal wall of the subject many times.

COVID-19 Testing: Throat swab test

Throat swab testing: Often used in the testing process because it is more convenient and fast to collect, and it is more acceptable to the public, but the risk of exposure is also greater.

Anal swab test

This test method is a method of inserting a test swab into the anus and taking a sample at the fold of the anus or taking a sample at 2 to 3 cm for a new coronavirus test.

Many patients reject anal swab testing, but anal swabs can improve the accuracy of testing for new coronavirus infections to a certain extent. Some patients indeed have negative throat swabs, but positive ones are detected by anal swabs. In some patients, the anal swab test was still positive after the other two tests turned negative.

Why do multiple nucleic acid tests need to be performed?

Multiple nucleic acid tests are necessary for epidemic prevention and control.
A negative nucleic acid test does not mean that the tested person is not at risk of infection. Any detection method has the possibility of errors, especially in high-risk areas. To ensure the accuracy of the inspection results and better prevent and control the spread of the epidemic, multiple rounds of inspections must be carried out. There are also the following reasons for taking multiple rounds of detection:

After virus infection, the human body has a certain value-added period. When testing, if the virus in the body does not reach a certain concentration, we may not detect the virus.

When the specimen was collected, due to the different sampling methods, no virus cells were collected. False-negative specimens can also lead to inaccurate collection results.

Errors in the transportation process and storage of samples for inspection will also affect the results of nucleic acid testing.

Therefore, for risk areas and special populations, multiple rounds of nucleic acid testing must be carried out to more accurately and effectively detect the virus source, so as to better and more accurately prevent and control and identify infected people, and cut off the source of the virus. No matter what kind of inspection process, attention must be paid.

Nasopharyngeal Swab Sample

Nasopharyngeal Swab Sample (Nasal Swab)

The nasopharyngeal swab: A specimen collection tool used to collect cell samples from the nasopharynx (above the throat).

When a patient develops an upper respiratory tract infection, doctors can use the collected samples to detect it, especially when the patient still has a fever.

In the experiment, technicians can detect common sources of infection, including potential pathogens such as the new crown and swine flu.

How is the COVID-19 nasal swab test performed?

Such tests can be uncomfortable for patients, but can quickly identify serious respiratory illnesses, especially those that require isolation or infection prevention measures to protect other patients.

Doctors can use cell cultures to determine the type of current infection. Factory-produced nasopharyngeal swabs cannot use natural substances such as cotton, as they may contain some impurities that will affect the detection.

Nasopharyngeal Swab materials

The nasopharyngeal swabs produced and sold by Cell Medical Company are flocked materials. Learn more about flocked swabs.

CellMedical flocked swabs are famous for their stable and reliable performance and excellent absorption and elution ability.

In general, a caregiver can place a sealed package (safety bag) next to the patient, and the caregiver places a sample container next to the patient, which contains a culture medium that maintains cellular and microbial viability for evaluation. This is the viral transport medium.

Laboratory technicians can detect the source of infection through nasopharyngeal swabs, and they should wear gloves and masks when collecting nasopharyngeal swabs.

Face protection is an effective measure to prevent patients from contracting respiratory diseases.

Nasopharyngeal swab collection

When taking the sample, gently insert the swab into the nose by hand, pushing it all the way to the nasopharynx. Patients often experience discomfort, convulsions, or spasms; for this, they sometimes need to suppress this response by leaning their heads against a wall or pillow.

When the nasopharyngeal swab is fully in, the caregiver can briefly swirl to collect the cell mixture, remove it, and place it in the specimen collection container. (Virus sampling tube)

After the sampler obtains the sample, he should immediately send it to the laboratory for PCR testing.

Waiting or not storing at low temperature may kill microorganisms that may be present in the sample, resulting in false-negative test results.

Patients usually get results within a day or two.

Inspection is capable of scanning for many common microorganisms.

When infectious diseases appear in epidemic areas, nasopharyngeal swabs and other microorganisms can be labelled to detect new crowns, swine flu and other microorganisms.

The doctor can try the test results to guide the patient’s treatment.

They can also help epidemiologists track the movement of diseases in the community, which is very useful for controlling disease outbreaks.

How accurate are saliva swab DNA tests?


							

					Posted on   by  				

			
		


					

				
Is the DNA test of the saliva swab accurate?


Many people doubt the accuracy of the saliva swab test.


However, you can rest assured, because the accuracy of oral saliva swab testing is as accurate as other DNA testing methods.


Moreover, this is not the same as a finger puncture or a blood test, it is not painful at all.


In recent years, DNA testing has become more and more popular.


Whether you want to confirm your parental relationship, understand where your genes come from or want to optimize your exercise.


We are currently working on direct-to-consumer DNA testing of saliva swabs.


You have decided to use DNA testing to better understand your body and optimize your training.


However, before you take the first step and buy a set of home DNA testing kits, you should have some concerns.


Although most of the feedback and research has been confirmed to be positive, we are here to learn more about this and help you make an informed decision.


How much saliva is needed for a DNA test?


Saliva Sample Collection Kit :Disposable saliva DNA RNA sampling tube
Saliva Sample Collection Kit: Disposable saliva DNA RNA sampling tube


2ml-4ml.


The saliva collection components are easy to use, and each set has detailed instructions.


You can provide samples for different health conditions, including common medications used during pregnancy, colds or flu (including medications for acid reflux or heartburn).


But if you want to use drugs to reduce the white blood cell count, such as chemotherapy, you’d better wait two weeks or wait until the white blood cell count returns to normal.


After mixing with DNA stabilizing buffer, the temperature range of your saliva sample (-4oF to 122oF) is stable.


Please send the collected samples to the laboratory as soon as possible.




Is the DNA test at home accurate?


Yes, DNA testing at home is very accurate.


You will only encounter errors when the genetic sample is damaged (for example, you have eaten before the sample is collected) or the laboratory quality is poor.


Therefore, it is necessary to choose a well-known DNA testing supplier for testing.


An accurate genetic test report can know in advance whether the body is in danger of disease.


By improving the living environment and behaviour habits, avoiding or delaying the occurrence of the disease, or determining whether there is a specific drug in the case of malignant disease.


Target, so as to more accurately select the treatment method.


The results in each report are derived from at least three peer-reviewed research papers.


It just repeats the genes that have an impact on health, health and nutrition.


This means that you can change the way of real-life based on the genetic variants you carry.


Through strict internal and external procedures, we have passed ISO27001 certification to identify risks, evaluate all control systems, improve our reliability and security, and comply with international data security standards, so as to ensure that our customers and business partners can trust us.


What can you do to ensure that your DNA test results are accurate?


In order to ensure that your DNA test results are accurate, you need to follow the instructions at the back of the box.


Before starting, please read the instructions carefully:


Before wiping dry, make sure you have nothing to eat or drink.


-The best time to take the exam is to brush your teeth in the morning and the first thing before drinking the first cup of tea.

Before taking the test, it is best to open the sealed mouth swab to ensure that it will not be affected.


After removing the cotton swab, open your mouth and use a pointed tip (cotton swab, slightly larger) to gently wipe your cheeks.


Try not to scrub vigorously, because the important part of the sample is saliva.


Be sure not to put paper towels in the plastic container provided.


Take care to break the pole where it is needed.


Fill out the attachments, sign and seal the enclosed envelope, and then send it to the laboratory for inspection.


Bear with patience and watch your test. This process will start with the receipt of samples in the laboratory and will take 10-14 days.


Is the accuracy of mouth swab detection relative to other DNA collection methods?


Because the saliva swab is noninvasive, many people question its accuracy.


However, you can rest assured that the accuracy of oral swab detection is as accurate as other DNA detection methods. And, unlike finger punctures or blood tests, it doesn’t hurt at all.


Whether you are building a cabinet in IKEA, pressing a map or doing DNA testing, you can get accurate results as long as you follow the instructions.


Remember, DNA testing is wrong only if your test results are wrong or you don’t follow the instructions.


Cost is an important factor in performing such tests, so it must be studied.


Often, you don’t just pay for the test suite. You also have to pay a test fee to analyze your results. If the test you selected does not belong to the laboratory, please choose a supplier with a good reputation and excellent laboratory.


Every laboratory we use will conduct regular spot checks to ensure that your samples have been tested correctly and your results are 100%.

How does a Covid Mouth Swab Test work?


I went for a swab test for the new coronavirus the day before yesterday, and the result came out yesterday and it was negative. Some friends asked me, is the throat swab test painful? How to do it? What are the types of COVID-19 tests? What COVID-19 test is more accurate? Today, Dr Lee came to give everyone a popular science.


You can use a variety of tests to determine whether you have COVID-19. Some tests are collected by mouth swabs, and some are collected by nasal swabs or saliva. In the experiment, an oral flocked swab was used to collect samples from the oral cavity for oral inspection. This is different from a saliva test, which spits out saliva into a small container.

What is a mouth swab? Painful?


The COVID-19 test is the most important way to diagnose the new coronavirus. Nucleic acid is the genetic material RNA of the new coronavirus. The nucleic acid test is to check a certain segment of RNA. If it is positive, it means that you are infected with the new coronavirus.

According to different sampling sites, nucleic acid detection can be divided into many types, such as throat swabs, anal swabs, tracheal secretions, alveolar lavage fluid, and so on.

Among them, throat swabs are the most commonly used, and oropharyngeal or nasopharyngeal secretions are taken for laboratory tests.


Oropharyngeal swab, the inspection process is very fast, no more than 10 seconds, only needs to open the mouth, and the staff uses a cotton swab to take a sample in the oropharynx.

When sampling, there will be a slight pain, and when the throat is stimulated, there will be a feeling of vomiting.


But the feeling is not strong, and it will be fine for a while.


According to British colleagues, the nasopharyngeal swab is more uncomfortable, and the pain will be greater because the nasopharyngeal swab needs to be completely pricked into the nose. Learn more about nasal swabs Please click here


How to interpret the results of the Oral swab test?


Nucleic acid(COVID-19) testing usually produces results within 24 hours. If you check today, the results will be known the next day. The results are nothing more than two cases, negative or positive.


Does negative mean there is no infection?


It is not 100% certain, because nucleic acid testing has a certain probability of false negatives. For example, in the early stage of the disease, the virus content is very low, and it may not be detected, or the sampling is not taken properly, and the sensitivity of the detection reagents, operation Whether it is standardized or not, etc., are affected by many factors.


How to do a mouth swab COVID-19 test


How to use mouth swab
How to use mouth swab


There are different ways to do a COVID-19 mouth swab:


    

  • 1. The patient needs to sit with his head back, open the mouth, and then remove the nasal cavity and the secretions on the oral surface.
    • 

  • 2. The collector uses a special tongue depressor to fix the patient’s tongue, and then cross the throat with the collecting tool, and the tonsils directly to the position where the specimen is taken.
    • 

  • 3. After repeated wiping of the collection table, mucosal cells can be directly extracted.
    • 

  • 4. Take out the collected throat swabs. Be careful not to touch the oral mucosa, tongue and saliva secreted by the oral cavity during this process to prevent inaccurate test results.
    • 

  • 5. Put the extracted throat swab into a special device and transport it to the laboratory for examination.
    • 



You may need to take specific steps before the test so that the results are as accurate as possible. If you need to book an appointment, ask if there’s anything you should avoid on the day of your test. Some types of tests that use saliva require that you don’t eat, drink, smoke, brush your teeth, or chew gum 30 minutes before the test (FDA, 2020).


What are the types of COVID-19 tests?


In the UK, when diagnosing COVID-19, there are usually two main types of tests:


Molecular biology tests, such as PCR (polymerase chain reaction), are used to find viral genetic material.


Look for the antigen detection of the virus shell.


Either test can be done with a nasal swab or a mouth swab. Saliva can also be used for PCR detection (FDA, 2021a). Although saliva and oral swab tests may sound the same thing, they are actually slightly different. The saliva test requires you to spit into the tube, while the oral swab test is to wipe a sample in the mouth with a cotton swab.


Nasal mucosal secretions follow the same rules, but the difference is that you or a health care professional collect the sample from your nose instead of your mouth.


Another type of test is antibody testing (also called serological testing). These two data can’t tell you whether you are infected now but can tell you whether you have been infected before or if you have been vaccinated before. Antibody testing usually requires a blood sample.


What COVID-19 test is more accurate?


How to interpret the swab test results


Nucleic acid testing usually produces results within 24 hours. If you check today, the results will be known the next day. The results are nothing more than two cases, negative or positive.


Does negative mean there is no infection?


It is not 100% certain, because nucleic acid testing has a certain probability of false negatives.


For example, in the early stage of the disease, the virus content is very low, and it may not be detected, or the sampling is not taken properly, and the sensitivity of the detection reagents, operation Whether it is standardized or not, etc., are affected by many factors.


With the continuous optimization of detection methods and the continuous updating of reagents, the sensitivity of detection is now higher, and the probability of false negatives is lower than before.


If it is negative, there is a high probability that it has not been infected with the new coronavirus.


For some high-risk groups, close contacts, and suspected clinically highly suspected cases, one negative may not be enough, and two, three, or even multiple tests may be required.


Notice


Even if you have been tested before, COVID-19 testing is difficult to cope with. But the test should be able to relieve stress and not cause stress.

In any case, the knowledge of COVID detection technology is constantly changing. If you want to know if you want to be tested and how it works, we will help you at any time. Here is some information about oral swab COVID testing and other information to determine whether COVID-19 is COVID-19, you need to know.

What Makes Flocked Swabs Different than Traditional Swabs?




We all know cotton swabs, but we may not know flocking sampling swabs.


XiaoLee will discuss with you what flocking swabs are and what are the advantages of flocking swabs over cotton swabs.




Our company uses the existing technology “spraying technology” to vertically attach millions of nylon microfibers to the head of a medical-grade handle through the flocking process of electrostatic charge. The function of vertical nylon fiber is similar to that of a soft brush. Using this soft brush in the sampling process makes the user feel no foreign matter. At the same time, the flocking swabs used in different parts adopt different breaking points, and the rod adopts different thicknesses to make the softness different.


Traditional cotton swabs cannot completely collect and elute samples while flocking swabs can elute 95% of samples.


Therefore, the use of flocking swabs has great advantages for various sample collection applications.


For example, nasal swab, the upper end of the rod is thinner and softer, and its breaking point is longer.

About Flocked swab specimens?


The detection of viral nucleic acid sequence based on reverse transcription-polymerase chain reaction (RT-PCR) technology is the main method for large-scale screening of new coronary pneumonia. Normally, nucleic acid detection technology has the characteristics of early diagnosis, high sensitivity and specificity, but Sample collection and storage, personnel operation, nucleic acid extraction, kit performance, etc. are all causes of false-negative or false-positive test results.


Flocking swabs are the main test samples for PCR. In the selection of raw materials, flocking glue plays a key role in the collection and release efficiency of swabs. Whether to use high-quality water-based flocking glue is the main factor that affects the water absorption and hydrophilicity of villi.


Are flocked swabs used for flu testing?


Of course！


Influenza is very common in winter and spring. The clinical manifestations are mainly high fever, fatigue, headache, cough, and systemic muscle pain and other symptoms of systemic poisoning, with mild respiratory symptoms.

    About COVID-19 Swab Test
    

    The new crown virus has mutated continuously.
    

    From Delta to Omi Keron, the COVID-19 virus has continued to mutate, and the global epidemic is prevalent at a high level.
    

    Canada announced that all entry personnel from all countries except the United States are required to be tested for the new coronavirus.
    

    At this time, whether you are leaving the country or entering the country.
    

    I even worry or doubt whether I have contracted the coronary disease.
    

    Perhaps understanding the new coronavirus test has become a compulsory course for most people.
    

    What is the new crown swab test, how to collect a nasopharyngeal swab?  Is nasal swab sampling painful?  If your test result is positive, what do we need to do?  Why do most virus tests choose to flock swabs? Is nasopharyngeal swab accurate? Should you be tested for nasopharyngeal swab samples?
    

    We talked with Dr. Li of Cell medical to learn more.
    

    What is the COVID-19 test and what are the test methods?
    

    Nucleic acid detection (RT-PCR Test) method, antibody detection, and antigen detection.
    

    A swab test simple, effective, and fast way to detect COVID-19.
    

    Including nasopharyngeal swab testing and oropharyngeal swab testing.
    

    Medical staff will use flocked swabs to take samples from the nose and throat and put them into the virus sampling tube.
    

    There are two types of swab sample testing: molecular test (PCR) and antigen test.
    

    How to perform a COVID-19 nasal swab test?
    

    The COVID-19 nasal swab test involves inserting a 6-inch flock (a long stick with a very soft brush) into the cavity between your nose and mouth (nasopharynx).
    

    The medical staff inserts the flocking swab into each nostril for about 15 seconds and rotates it several times to collect enough samples for testing.
    

    The samples are then sent to the laboratory for testing, and our test results are usually known within or within the next day
    

    Since the nasopharynx is in a sensitive position of the body, it will produce a lot of very strange sensations.
    

    On the one hand, the swab is inserted deeply into your nose and it irritates the lacrimal glands.
    

    At this point, you don’t know if you are moved to tears or you are crying in pain.
    

    The nasal swab test is not very painful, but it is very uncomfortable. Some people may have nausea during the nasopharyngeal swab test. Nasal swab painful.
    

    Because the swab will also touch the back of your throat, this reaction is normal.
    

    Whether it is tearing or nausea, nasal swab testing is a common phenomenon.
    

    Don’t worry, everything is normal.
    

    Are there other types of COVID-19 swab test methods available?
    

    Yes, an oropharyngeal swab is one of the options.
    

    Of course, if you want to experience another feeling, an anal swab test is also a good choice.
    

    But they are not as sensitive as the COVID-19 nasal swab test.
    

    Israel’s development of the new coronavirus “saliva detection method” saliva detection still needs scientists to confirm on a larger scale. There is no conclusion yet, but it is promising.
    

    In addition to nucleic acid testing for the detection of viral genetic material, there is also antigen testing.
    

    Currently, nasal swab testing for COVID-19, including nucleic acid testing, is still the best choice.
    

    How about the covid test kit at home? Are their results reliable?
    

    The home covid test kit sounds very attractive.
    

    Home covid test usually refers to individuals collecting samples of themselves or their family members through sampling swabs.
    

    We put the collected samples in test tubes with a virus transport medium, and then transport them to the testing facility.
    

    Although you can use the Home covid test kit to test COVID-19 safely and comfortably in your own home.
    

    However, Dr. Li suggested that it should be carried out at a professional testing institution.
    

    Because the quality of the samples we collect and the integrity of the samples during transportation will affect the sampling results.
    

    How accurate is the nasal swab test for COVID-19?
    

    How to obtain a precise nasopharyngeal swab specimen?
    

    Polymerase chain reaction (PCR) uses a piece of DNA as a template.
    

    Then, with the participation of DNA polymerase and nucleotide substrate, the DNA is amplified to a sufficient amount for structural and functional analysis.
    

    Pcr nasal swab test can be said to be very sensitive.
    

    Scientists use PCR technology to amplify a small amount of RNA in the sample into deoxyribonucleic acid (DNA) and replicate it until COVID-19 (if present) is detected.
    

    The following may affect the accuracy of PCR nasal swab sampling.
    

    1. Smoking, drinking or chewing gum 30 minutes before use may also interfere with the test results.
    

    2. Touching the swab with the hand or other objects and using the tip of the cotton swab will affect the accuracy of the detection.
    

    Of course, the professionalism of the most important sampling personnel, we have to choose a professional testing agency for testing. And professional VTM Kits.
    

    What should I do if the new coronary pneumonia nasal swab test is positive?
    

    Very bad news!
    

    If the COVID-19 nucleic acid test is positive, a single room isolation treatment should be carried out immediately.
    

    Consultation by in-hospital experts or attending physicians will conduct multiple tests.
    

    Under the premise of ensuring safety, the patient is safely transferred to a designated hospital for diagnosis and treatment.
    

    Don’t worry. You need to actively cooperate with treatment
    

    Otherwise, life is likely to be in danger, and large-scale infections will also occur.
    

    In addition, proper physical exercise should be carried out in life to enhance the individual’s immunity. Colds and fatigue should be avoided.
    

    Don’t do strenuous exercise, so as not to aggravate the disease.
    

    A friend around me was infected with COVID-19. But my nasopharyngeal swab was negative. Is there any way to confirm that I have had it or am I immune to it now?
    

    Certainly.
    

    Antibody test, also called serological test, can detect the antiviral protein IgM and IgG antibodies produced by your immune system in the blood.
    

    What are the types of samples for serum antibody testing?
    

    It is generally blood, including serum, plasma, and whole blood.

    How to obtain a nasopharyngeal swab specimen?
    

    Overview.
    

    Nasopharyngeal swab specimen collection of respiratory mucosal surface specimens is a method for the diagnosis of Covid-19 novel coronavirus in adults and children.
    

    This operation can also detect patients with suspected respiratory infections caused by other viruses and bacteria.
    

    There are no special contraindications for nasopharyngeal swab specimens. However, clinicians should treat the following conditions with caution: the recent history of nasal trauma or surgery, severe nasal septum deviation, chronic nasal obstruction, and severe coagulation.
    

    Preparation for nasopharyngeal swab specimen sampling.
    

    The nasopharyngeal swab is a special sampling tool, which consists of a sampling head made of soft plastic or flocked nylon. In addition to nasopharyngeal swabs, operators also need personal protective equipment (PPE) such as isolation gowns, non-sterile gloves, protective masks, and face shields.
    

    Before starting to use, please make sure that all virus sampling tubes are labeled, and the analysis application form is filled incorrectly.
    

    Nasal Swab Sampling Steps
    

    We recommended that patients with suspected Covid-19 type coronavirus infection wear masks.
    

    The patient took off the mask and blew his nose with a paper towel to remove excessive secretions from the nasal passages.
    

    Take out the tissue. Slightly lift the patient’s head so that it can wipe into the nasal passage. Ask the patient to close his eyes to alleviate the slight discomfort caused by the operation.
    

    Along the nasal septum, gently push the swab above the bottom of the nasal passage forward until you feel a sense of resistance indicating that the swab has reached the nasopharynx.
    
Insert the swab in the nostril parallel to the upper jaw.
    

    If resistance is encountered during pushing the flocked swab, the scraper should be withdrawn, try to adjust the angle and then push again, at the same time closer to the bottom of the nasal passage.
    

    The depth of the nose insertion should be equal to the distance from the nostril to the opening of the external auditory meatus. CDC recommends keeping the sampling head for a few seconds after it reaches the nasopharynx, allowing the sampling head to absorb the secretions, and then slowly rotating the swab to discharge it slowly (people who have done nasopharyngeal swabs will appreciate which kind of sourness Cool feeling). Your institution may also recommend sampling for a few weeks after exiting the spin. Ask the patient to wear a mask.
    

    Nasopharyngeal swab specimen processing.
    

    Open the sampling tube with virus transport medium, put in the flocking swab, fold out the sample tube in the groove, and discard the tail. Tighten the label sampling tube cover, and wipe the sampling tube with a sterile wipe.
    

    Then place the sampling tube in the biohazard bag opened by the assistant. Some departments may require you to put the samples back in their original packaging and then send them for inspection. According to CDC guidelines, process the swab sample directly, or put the sample in a preservation solution or store it at room temperature.

    Flocked swabs for sample collection
    

    The flocked swab deposits nylon fibers on the surface of the medical ABS rod in order in a certain direction through the electrostatic field to form a brush layer. The layers are fully parallel and perpendicular to the surface of the internal rod.
    

    The brush head can be used for Virus cell collection.
    

    It can be used for sampling the natural cavities of the human body such as oral cavity, nasopharynx and laboratory detection.
    

    flocked swabs for sample collection
    flocked swabs for sample collection
    

    Why flocked swabs?
    

    The flocking swab deposits nylon fibers on the surface of the medical ABS rod in order in a certain direction through the electrostatic field to form a brush layer. The layers are fully parallel and perpendicular to the surface of the internal rod. The brush head can be used for DNA collection. It can be used for sampling the natural cavities of the human body such as oral cavity, nasopharynx and laboratory detection.
    

    So that there is no absorption hole in the sampling area of the whole sampling swab.
    

    And the sampling sample will not be dispersed and retained in the fiber, which is conducive to faster and more efficient elution.
    

    Traditional cotton swabs can not completely collect and elute samples, while flocking swabs can elute 95% of samples.
    

    Therefore, the use of flocking swabs has great advantages for various sample collection applications.
    

    Nasopharyngeal flocked swab;
    

    Flocked swabs have some advantages;
    

    1. Sampling is comfortable and easy to use;
    

    Flocking swabs now basically use “spray technology”, which vertically attaches millions of nylon fibers to the head of medical ABS swab rod through the flocking process of electrostatic charge.
    

    The function of the vertical nylon fiber is similar to that of a soft brush. The use of this soft brush in the sampling process makes the user feel free of foreign objects. At the same time, the flocking swabs used in different parts adopt different breaking points, and the rod adopts different thickness to make the softness different.
    

    For example, the nose swab is thinner and softer at the upper end of the rod, and the breaking point is longer, which fully conforms to ergonomics.
    

    2. Flocked swab samples release more;
    

    The capillary action between nylon fiber bundles promotes the strong hydraulic absorption of liquid samples. The sample is kept on the surface to make elution easier. It is much larger than the traditional winding cotton swab. The experimental research shows that the collection and release of flocking swab can reach 95% of the sample, while the cotton swab is only about 20%.
    

    Because most of the samples collected by the cotton swab are easy to be intercepted in the fiber matrix layer of the head during release, it is not easy to release or release a small amount.
    

    3. Flocking swab has biocompatibility and is an ideal choice for PCR;
    

    In order to limit the damage to the sample and improve the accuracy of detection, while the flocking swab is PCR compatible and does not contain RNase and DNase.
    

    Operation method of flocked nylon swab:
    

    Take the sampling method of oropharyngeal swab as an example;
    

    1. First, ask the patient to sit down, then let the patient tilt his head back, open his mouth, and make an “ah ~” sound.
    

    2. The sampler fixed the patient’s tongue with a tongue depressor, and used a flocking swab to cross the root of the tongue to the posterior pharyngeal wall, tonsil recess, lateral wall, etc.
    

    3. Wipe repeatedly for 3 ~ 5 times to collect mucosal cells.
    

    4. Slowly take the swab out of the mouth, vertically put it into the virus preservation solution, break the tail of the swab, and tighten the sampling tube to avoid leakage.
    

    5. Send to the laboratory for testing as soon as possible.
    

    Swab flocked matters needing attention:
    

    1. The swab shall be placed vertically in the sampling tube, and shall not be wiped to the bottle mouth to avoid pollution.Viral Transport Medium.flocked swab copan.
    

    2. It is best to send it or send it to the laboratory for inspection on the day of sampling.
    

    3. Before submission for examination, it must be verified that the specimen is consistent with the submission form. The appearance of the sampling tube must clearly write the patient’s name and basic information.
    

    4. The submitted samples must submit (or submit the electronic version in advance) screening information form, inspection form and other materials.

    To do a good job of normalization prevention and control, we should accelerate the improvement of detection capacity and carry out nucleic acid and antibody detection on a large scale.
    

    This is not only conducive to accurate prevention and control, maintaining people’s health, but also conducive to the rational flow of personnel and promoting the full resumption of work and production.
    

    Nasopharyngeal swabs are used for nasopharyngeal sampling of respiratory diseases such as COVID-19, influenza, avian influenza and hand foot mouth disease.
    

    For nasopharyngeal Swab Pcr Test, Pay Attention to the Following Points:
    

    1. Please do not take antibiotics a few days before rhinitis swab Pcr Test.
    

    2. Do not rinse your mouth with disinfectant or smear the lesion a few hours before making a nasopharyngeal swab.
    

    3. Don’t eat, smoke or drink a few hours before making a nasopharyngeal swab.
    

    4. If the patient’s turbinate is hypertrophic and the nasal tract is narrow, and the insertion resistance of nasopharyngeal swab is relatively large, we can’t use force rashly. We can try to use the other nasal cavity, or directly use oropharyngeal swab to collect.
    

    5. After sampling, gloves shall be replaced, hands shall be disinfected, and disinfectant shall be sprayed on the place where the patient has touched.
    

    In special times, you should also remember to wear a mask and do a good job in personal hygiene. Once you find a virus, please isolate it to avoid re infection.

    What is a flocked swab？
    

    NYLON FLOCKED SWABS FEATURES:
    

    *Ergonomics and anatomical design:
    

    Patient comfort and cell sample collection efficiency improved at the same time.
    

    nylon flocked nasopharyngeal swab
    nylon flocked nasopharyngeal swab
    

    *High-quality sample elution:
    

    Unlike traditional swabs, when the sample does not come out of the mattress core.
    

    Nylon Flocked Swab has an open fiber structure that can immediately transfer the sample cells to the liquid medium.
    

    *Rapid absorption (the improved sample collection)
    

    The static electricity is sprayed on the fibre and fixed evenly and vertically on the top of the coater.
    

    This powerful capillary effect quickly absorbs cell samples.
    

    *Increase analysis sensitivity:
    

    Nylon flocked cotton swab can quickly elute more than 95% of the original sample,
    

    so it is easy to improve the analytical sensitivity.
    

    *Just collect, capture and transport:
    

    Peel off the pouch, collect cell samples,
    

    and clip the applicator shaft into the provided delivery medium or cuvette tube.
    

    *Quantitative volume transfer:
    

    Measurable and consistent absorption and transfer from the patient to the test tube,
    

    without an internal mattress core,
    

    disperses and holds precious samples like traditional fiber swabs.
    

    In contrast, the entire sample remains close to the surface for rapid and complete elution.
    

    *Vertical nylon fiber:
    

    Such as a soft brush, can improve the collection of cell samples.
    

    The capillary interaction between nylon fiber bundles not only facilitates the strong water absorption of cell samples
    

    but also keeps the cells close to the surface, which is more convenient for elution.
    

    *Certified without inhibitors and interferences:
    

    Swabs collected are certified DNase, RNase free, and human DNA free.
    

    They also do not contain any PCR inhibitors.
    

    Certificate of analysis for each batch.
    

    *Ideal for automation:
    

    Compared with the traditional fiber wound swab, the 4n6 DNA swab only released a small amount of fibre during the extraction process.
    

    This avoids the risk of clogging the pipettes and probes used by the liquid handling robot.
