Methicillin-resistant Staphylococcus aureus (MRSA) is increasingly rampant, and its infection spreads almost all over the world.

Together with AIDS and hepatitis B, it has become the three most difficult infectious diseases in the world.

How to prevent and control MRSA has become a problem that we cannot ignore.

The long-term treatment of MRSA infection, in addition to the direct economic burden on patients, will also generate some indirect costs, such as isolation, disinfection and so on.

n response to the prevalence of MRSA, we should propose strict detection and control measures.

MRSA screening is an important part of this.

Medical swabs are one of CellMedical’s specialties. Our goal is to ensure that our swabs give end users what they really need so they can always perform at the highest level.

In this article, we review what MRSA is, why using a nasal swab is the most effective way to test for MRSA, and how to perform a nasal swab test for MRSA.

What is MRSA?

MRSA, known as Methicillin-Resistant Staphylococcus aureus.

A highly drug-resistant strain of bacteria found mainly in people with long-term chronic diseases.

It is naturally resistant to penicillin and cephalosporin antibiotics, and also has varying degrees of resistance to commonly used erythromycin, etimicin, ofloxacin and other drugs.

Mainly seen in patients with bloodstream infection, lung infection and other site infections.

If the treatment effect is not good after a variety of antibiotic anti-infection treatment, it is necessary to consider whether there is mrsa infection. This bacterium is only effective against antibiotics such as vancomycin, teicoplanin, and linezolid.

MRSA is contagious through person-to-person contact and when a contaminated person touches an object or surface and leaves behind germs that can spread.

About 126,000 people are hospitalized and 19,000 die from the bacteria each year.

MRSA Nasal Swab

A nationwide cross-sectional study of MRSA screening in more than 10,000 patients showed that screening sites included the nose, throat, underarm, perineum, and wound or implant sites. Nasal swabs identified only 66% of MRSA carriers, and further swab testing could increase the detection rate.

Nasal and perineal swabs were identified in 82% of patients, with the axilla being the least useful site for carrier identification (8% detection rate).

Standard screening methods should include at least two swabs (nasal swab plus perineal or pharyngeal swab).

According to the American Society for Microbiology, nasal swabs have a higher detection rate of MRSA than traditional swabs. Flocked swabs provide better sample collection because their brush-like tips release more target cells and retain more liquid sample than foam swabs.

Our flocked-Swab sterile swabs are designed for the collection and transport of clinically significant bacteria.

With molded breakpoints, sampling is fast, safe and convenient.

How to use MRSA Swab?

Once a sampling swab and transfer medium, such as CellMedical’s flocked-Swab media transfer system, has been selected, testers should wash their hands and wear clean gloves.

The process is as follows:

  1. Remove the nasal swab.
  2. Measure about 2 cm with a swab and mark with your finger.
  3. Insert a cotton swab about 2 cm (about 3/4 inch) into one nostril.
  4. Insert the swab into the nostril perpendicular to the nose (face), rotate the swab against the anterior nasal mucosa for 3 seconds, then gently rotate 3 times. .
  5. Using the same swab, repeat for the other nostril.
  6. Place the swab back into the virus delivery medium.
  7. Place the end of the swab firmly so that the tip of the swab is in contact with the wet swab.
  8. Tighten the cap of the tube, mark it well, and put it in a plastic bag and seal it.

Nasal Swab Covid Test

Some people need to be tested for COVID-19 with a quick swab.

The pros are sure: If it is possible for you to test both the nose and the throat at the same time.

Officially, the FDA follows inspection guidelines. Simply put, observe the subtests consistently during this period.

COVID19 test flocked swabs to exteriors.

What is a nasal swab?

COVID Swab test

COVID Swab test

A nasal swab is a test that checks for viruses in the nasal cavity, and the result is a test that checks the nasal cavity by a method.

Because of rhinitis in the nasal cavity, sinusitis, sinusitis, nasal cavity in the nasal cavity and other problems.

There are several respiratory infections, including the flu, COVID-19. A nasal swab can help your doctor determine the type of infection you have and which treatment is definitely best for you.

The test can be done by taking a sample of cells from your nostrils or nasopharynx.

A nasopharyngeal flocked swab is the uppermost part of the nose and throat.

Other names: Anterior nostril examination, turbinate swab, NMT swab, nasopharyngeal culture, nasopharyngeal swab

Why do I need a nasal swab?

01The positive detection rate of nasal swabs is higher.

When using a throat swab to detect the new coronavirus, the base of the tongue will instinctively prevent the cotton swab from going deep, and the cotton swab is not easy to reach the back wall of the pharynx. . The nasal swab is easier to reach the tested site and can stay in the nasopharynx for a long time, and the test results are more accurate. Students returning to school from the north and south of the river and by various means of transportation require us to improve the accuracy of testing in a responsible attitude to everyone’s health.

02Nasal swabs are safer for nucleic acid collection personnel.

During the nasal swab test, the tested person needs to wear a mask with only the nostrils exposed; while for the throat swab test, the tested person needs to open his mouth wide, and the exposed area is large. If the tested person coughs and retches, the nucleic acid tester may face a greater risk of infection. Once the testers are infected, the risk may spread to a wider range of people.

03 Throat swabs may be more uncomfortable than nasal swabs.

Throat swabs are collected across the base of the tongue to the posterior pharyngeal wall, tonsillar recesses, sidewalls, etc., and repeatedly wiped 3 to 5 times to collect mucosal cells. In response, nasal swabs were relatively less irritating to the mucosa.

The entire nasopharyngeal swab process:

What to do before swab test

nasopharyngeal swab

You will throw your head back.
Your healthcare provider will insert the swab directly into your nostril until it reaches your nasopharynx (the top of your throat).
Your supplier will rotate the swab and remove it.
Do I need to do any preparation for the exam?
For nasal swabs, you don’t need any kind of special preparation.

This article
To talk to you in detail
Covid nucleic acid test!

But in the face of the “nucleic acid swab test”
This unfamiliar and familiar word
Do you have many questions?

Image source network

Do you want to do a nucleic acid test when you go back?

Will it be difficult to make an appointment for nucleic acid testing?

How long does it take to get the results of a nucleic acid test at the hospital?

Should I Swab My Throat or Nose for Rapid COVID-19 Tests?

To answer your questions.
Today.
I’m going to tell you.
Those things about nucleic acid testing.

01. What is nucleic acid detection?

At present, nucleic acid detection is the main method for laboratory diagnosis to determine whether a patient is infected with the new coronavirus. It can achieve early detection, early diagnosis, and early treatment. Real-time fluorescent PCR can be used to detect throat swabs, sputum or blood samples. to covid nucleic acid, or detected by viral next-generation gene sequencing.

simply put

Nucleic acid testing is done by

After collecting human secretions

Tested by the instrument

to see if we have the new coronavirus in our body

If so, the test result is positive

On the contrary, if it doesn’t, it’s negative.

02. How to test the COVID swab?

“Sir, oropharyngeal swab, nasopharyngeal swab, and anal swab, which one to choose?”

How do you do a nasopharyngeal swab?

Nasopharyngeal swabs must be performed with the patient sitting upright with the head in an upright position, as this allows for easy visualization and access to the nasal floor perpendicular to the central axis of the patient’s face.

Flocked Tip Swab Nylon Sterile Nasal Swab Stick

Flocked Tip Swab Nylon Sterile Nasal Swab Stick

Insert the swab into the patient’s nose and align it parallel to the nose and the base of the septum. As long as there is no obstruction in the nasal cavity, the swab continues to move in this direction until it reaches the nasopharynx, at which point the tester feels resistance.

Once the swab reaches the nasopharynx, a gentle rotation and two complete 360-degree rotations are recommended to allow secretions from this area to be absorbed.

Once the swab is removed from the patient’s nose, it is immediately inserted into a viral sample containing a viral transport medium. The handle of the swab extending through the opening of the vial was broken off to allow the tube to be closed.

So
Now that there are oropharyngeal swabs and nasopharyngeal swabs
Why add anal swabs?
To answer your questions
Let’s take a look at their respective advantages and disadvantages

The specific operation of the anal swab is as follows:

Soak a flocked swab in saline, insert it 2-3 cm into the anus, wipe from the folds around the anus, or rotate it gently inside the anus, and insert it into a test tube containing saline.

anal swabs

For fecal swab cultures, all of the above requires the use of sterile equipment and placing the swab in a sterile tube.

So
Now that there are oropharyngeal swabs and nasopharyngeal swabs
Why add anal swabs?
To answer your questions.
Let’s take a look at their respective advantages and disadvantages.

Oropharyngeal swab: relatively simple to operate, less irritating, suitable for large-scale screening. Therefore, the nucleic acid test of oropharyngeal swabs is mainly used in the screening of new coronary pneumonia for the epidemic-related population, which is used in the routine nucleic acid test clinic of the First Affiliated Hospital of NTU.

Nasopharyngeal swab: The technical requirements are high, the human body does not feel comfortable, and the accuracy rate is higher than that of the oropharyngeal swab. However, for some asymptomatic or mildly infected people, the condition recovers quickly after infection, and the pharyngeal nucleic acid may not be detected in 3 to 5 days.

Anal swab: high accuracy, reduce missed diagnosis. The study found that the duration of nucleic acid-positive feces or anal swabs of some infected persons is longer than that of the upper respiratory tract. Therefore, anal swab tests will be carried out for key groups such as isolation points or some imported overseas.

In conclusion.
The three swabs have different lengths.
If you have to test an anal swab.
Don’t be shy.
Whatever the swab,
It is a good swab that can accurately identify the virus.

During the outbreak of the new coronavirus pneumonia, while everyone is doing personal protection, they are also very concerned about the epidemic situation.

Originally, the social season in winter and spring was a period of the high incidence of common colds and flu, and the most important means to control the epidemic was to screen out the real patients with new coronary pneumonia from many respiratory patients.

The following small series will introduce some common virus sampling detection methods for you.

Nasopharyngeal swab

Collect nasopharyngeal swab specimens within 3 days of the onset of the patient as much as possible.

Measure the distance from the tip of the nose to the earlobe with a swab and mark it with your finger, insert the swab into the nasal cavity in the direction perpendicular to the nose (face), and the swab should be at least half the length from the earlobe to the tip of the nose so that the swab stays in the nose for 15 ~30 s.

Gently rotate 3 to 5 times, quickly put the swab into a sample collection tube containing 2 ml of lysis buffer (the same as the lysis buffer in the nucleic acid extraction kit) or a cell preservation solution containing RNase inhibitors, and insert the swab.

Then break the sterile swab rod near the top, screw the cap tightly and seal it with parafilm.

Oropharyngeal swab

Collect throat swab specimens from patients within 3 days of onset as much as possible. It is advisable to use a sterile flocked swab for sampling, wiping the posterior pharyngeal wall with moderate force, avoiding touching the tongue; quickly put the sterile swab into the collection tube used for collecting nasopharyngeal swabs, and break it near the top Sterile swab rod, screw cap tightly and seal with parafilm.

Anal swab (feces)

For patients with gastrointestinal symptoms such as diarrhea in the early stage of the disease, an anal swab should collect a stool sample (soybean size) of 3-5g.

The specimens were collected in a screw-cap specimen collection tube containing 2 ml of normal saline (RNase inhibitor can be added if available) and sealed with parafilm.

How to collect nasopharyngeal swabs

There is absolutely no need for the sampler to stand directly opposite the patient. Regardless of whether the patient is sitting or lying, right-handed patients can stand on the right side of the patient, and left-handed patients can stand on the left side for sampling operations.

The advantage of standing on the side is that if the patient has a cough, sneeze, etc., it can be avoided in time.

After the nasopharyngeal swab is passed through the nostrils.

It is perpendicular to the coronal plane of the head or the face and penetrates deep from the inferior meatus to the posterior wall of the nasopharynx, and it is enough to feel the wall.

The nasopharyngeal swab enters the nasal cavity to a depth of approximately the distance from the tip of the nose to the earlobe (see figure).

The “American Society for Microbiology Clinical Microbiological Specimen Submission Guidelines. ” We ask to twist the nasopharyngeal swab on the nasopharyngeal mucosa, hold it for 10-15 seconds, and then take out. Children’s cooperation is poor.

We generally take out the Flocked swab in three to five seconds after fully twisting it 2-3 times.

Except for paying attention to the depth of the swab. We should also note that there is always the habit of having the patient lift their head completely, bend the swab, and take a sample. This is wrong.

In fact, the above approach is wrong. This operation will cause the swab head to stay in an incorrect position. And the final sample obtained is not a standard nasopharyngeal swab specimen.

What is a Medical Swab

In the COVID-19 sampling, medical flocked swabs are the most commonly used testing method.

Application: oral mucosal cells, oral microorganisms, virus sampling and transportation, DNA/RNA collection, throat sampling, cervical sampling, nasopharyngeal sampling and other fields.

In addition, we can also use medical cotton swabs for the collection and transportation of DNA for paternity testing.

As well as the collection, preservation and transportation of flu specimens.

According to the material, medical swabs can be divided into cotton swabs, foam swabs, non-woven swabs, flocked swabs and other products. Among them, the market share of cotton swabs is higher, reaching 76%.

According to the application field, medical swabs include gynecological, cervical and vagina sampling swabs; oral, nose, and pharynx sampling swabs; laboratory test sampling swabs; virus and bacteria sampling; disposable sampling swabs; sterile cell sampling And other products.

However, due to the influence of new coronary pneumonia and the popularization of nucleic acid testing, the proportion of medical swabs used for specimen sampling is increasing.

With the continuous improvement of medical conditions in developing countries around the world, the application demand for medical swabs is on the rise.

In 2020, the global medical swab market will reach 400 million U.S. dollars, with an output of about 38.4 billion pieces.

Moreover, due to the development of the world economy, the price of medical cotton swabs has shown an upward trend.

Choose the right medical swab

Swabs are one of the most commonly used disposable devices in the medical industry. But how do you know which application to choose? We have put together a brief overview on how to choose the right medical swab for your specific needs.

Cotton swab

The tip of American pharmaceutical-grade spun cotton fiber has become the standard for applicators for all applications from basic patient care to crime scene investigation.

With strong water absorption capacity, softness, low cost and safety, the performance of the cotton swab is consistent and reliable.

However, it is generally not recommended to use cotton swabs for specimen collection.

why? The characteristics of this natural material prevent the sample from being effectively released, and the naturally occurring fatty acids in this material interfere with the processes used in microbiology and DNA extraction and have proven harmful to organisms.

Rayon cotton swab

"<yoastmark

Rayon is a synthetic fiber made from wood pulp.

Although classified as synthetic fiber, it is actually a natural material.

Unlike cotton, artificial fiber removes materials that may sample or react to samples for transportation and processing during the production process, so it is usually used to sample for diagnostic tests.

Polyester fiber swab

"<yoastmark

Swab head material adopts polyester filament winding.

Polyester fiber is used for microbial collection, rapid diagnosis and PCR detection.

The polyester scraper has a higher release rate, but its cost is higher than cotton swab and rayon swab.

Foam tip swab:

Foam swab

Foam swab

The swab made of medical polyurethane is a very good diagnostic material, especially suitable for cell sampling.

The number of holes on the surface is generally 100 PPI (holes per inch).

This material has good hydrophilicity and poor absorption of hydrophobic substances.

Used in occasions where resistance to chemical corrosion is required, and it is also used for DNA and microbial sampling.

Synthetic swabs (rayon and polyester) are used to collect bacterial culture specimens, rather than cotton swabs that may contain inhibitory or toxic substances.

Flocked swab:

flocked swabs

flocked swabs

First developed flocking technology for cosmetics and industrial production.

Because of the planting process and the use of multi-head bifurcated polyester fiber materials.

The flocked swab has a very high absorption and release rate, and it is also effective for molecular sampling and absorption.

Some institutions designate to conduct research on nucleic acid sampling and certain genome analyses.

At present, the development of swabs not only reflects the changes in the materials of sampling swabs, but new demands in the fields of nursing, testing, and scientific research have led to the multi-dimensional development of swabs.

What’s The Difference Between COVID-19 Rapid and PCR Tests?

What’s The Difference Between COVID-19 Rapid and PCR Tests?

As New Year’s Day approaches, the number of new crown infections is also rising. Therefore, once you have symptoms of infection. Or you are exposed to the new coronavirus. If you are going to an environment with a high risk of infection.

You must continue to be tested.

Currently two COVID-19 detection methods-polymerase chain reaction (PCR) test (also known as reverse transcription-polymerase chain reaction test) and a rapid antigen test.

So, which detection method should we choose? What is the difference between the two?

On the COVID-19 website, terms such as PCR, rapid test, and antibody test are difficult to understand and which one is correct for you. In this article, our goal is to explain the difference between the two most common tests for diagnosing COVID-19: rapid antigen test and polymerase chain reaction (PCR) test.

Rapid antigen test

Antigen test (often called rapid test). This test detects protein fragments specific to coronavirus. We can do the antigen test in a clinic, doctor’s office or hospital. The turnaround time for results is usually very fast, and in some cases, we can get report results within 15 minutes. There are usually false negatives (the results indicate that the patient does not actually have a coronavirus) or false positives (the results indicate that the patient does not actually have the coronavirus).

If you feel unwell and have undergone a rapid negative test, you may need to undergo a PCR test for further confirmation. However, when someone is at the peak of infection, rapid antigen testing usually provides accurate results because this is when the virus levels in the body are highest.

The rapid antigen test is usually used as a screening tool to detect that you may be infected with the new crown, but PCR monitoring is required to confirm the final result.

Although a negative rapid antigen test result does not necessarily mean that you are not infected, it at least protects your contacts than not testing at all.

PCR TEST

PCR swab tests are similar to rapid tests in several respects because they can be used in symptomatic or asymptomatic patients and can be tested with nasopharyngeal swabs.

The swab test is considered the “gold standard” for SARS-CoV-2 detection. This test actually detects RNA (or genetic material) unique to the virus, and it can detect the virus within a few days of infection, even for those who have no symptoms. This test can be performed in a clinic, hospital or even in your car. The turnaround time is longer, generally in the range of 2-3 days, but the result may be within 24 hours. When the demand is high, the result may take a week or more.

What if the rapid test is negative but there are still symptoms?

The current recommendation is that if you still have symptoms and the rapid test is negative, you should have a confirmation test (PCR test). This is especially true if you have high-risk exposures. High-risk exposure is considered to be contacted with a COVID-19 positive individual for more than 15 minutes within 24 hours, and the distance between you and the individual is no more than 6 feet.

What kind of test should be done? When will it be done?

RT-PCR (reverse transcriptase-polymerase chain reaction) detection if the following situations occur:

1. Symptoms of new crown infection appear.
2. Having contact with people infected with the new crown.
3. The rapid antigen test result is positive, and PCR identification is required.
4. The Ministry of Health requires testing before lifting the quarantine.
5. The Ministry of Health requires that an inspection must be carried out before obtaining permission to travel to a certain area.

If you want a quick antigen test:

1. Have a plan to go to a place with a high risk of infection.

2. Contact with high-risk groups (such as the elderly) and hope to protect them.
3. You have symptoms of COVID-19, but you cannot go to the PCR test site.
4. Activities with a large number of participants in the field, if indoor activities are carried out, the risk of infection is greater.
5. Check whether you have the SARS-CoV-2 virus as soon as possible.
6. Participate in regular COVID monitoring projects.

    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.

    On this page, you will learn:

    1. What is a mouth swab? Painful? 
    2. How to do a mouth swab COVID-19 test
    3. What are the types of COVID-19 tests?
    4. What COVID-19 test is more accurate?

    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.

    Covid Mouth Swab Test work

    Covid Mouth Swab Test work

    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.

    According to the US Chinese website, with the spread of the Omi Keron variant of the new crown virus in the United States, the epidemic situation in New York State, where the largest city of New York is located, continues to deteriorate.

    The number of newly confirmed cases hit a new high for two consecutive days on the 17th and 18th.

    New York case consecutive record high

    According to reports, on the 18th local time, New York State reported 21,908 new cases.

    Although the number of cases in New York State has increased, the number of hospitalizations and deaths is still lower than the previous peak of the epidemic. In New York City, many residents report that there have been long lines at swab testing centres in recent days.

    what is a flocked swab?

    The cell medical company flocking swab is made of nylon fiber flocking technology. The front end of the flocking swab rod is coated with nylon short fiber fixed vertically so that there is no absorption hole in the whole collection swab collection area. Learn more

    The sample will not disperse and remain in the fiber, which is conducive to faster and more efficient elution.

    To limit the damage to the sample and improve the accuracy of detection, the cotton swab is made of completely inert parts.

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

    what are flocked swabs used for?

    Flocked swabs are specimen collection devices that are ideal for use in diagnostic testing.

    They are capable of efficiently collecting organisms and cells at the collection site and have the ability to rapidly release cells.

    If the swab head is flocking, it is a flocking swab.

    1. Sample collection and transportation.

    The outbreak of the new crown epidemic, no matter where we are. We may have been exposed to nucleic acid testing, and most of the sampling swabs used by medical staff are flocked materials.

    The nasopharyngeal sampling swab is composed of a nylon short fiber fluff head and medical-grade ABS plastic rod. The role of nylon short fiber is like a soft brush, which can effectively improve the collection of cell material; the capillary movement between the fibers forms a strong hydraulic pressure, thereby taking in the liquid sample; at the same time, the sample is close to the surface of the swab and is easy to wash.

    The Cell VTM Universal Transport System is the leading transport medium for the collection, transportation, preservation and long-term frozen storage of clinical specimens containing viruses, chlamydia, mycoplasma and ureaplasma.

    4. DNA disposable sampling swab.

    By wiping blood, epidermis and other tissues, it can effectively contact the samples that need to be collected for DNA testing, making the DNA test results more accurate.

    5. Sterile swabs for cell sampling.

    6. Laboratory test sampling swab.

    Flocked swabs can collect more target analytes, and there is no sample residual volume, which speeds up the processing of the specimens.

    The swabs are sterilized and individually packaged. Beating improves the collection quality of cell collection swabs!

    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.

    Our flocked swabs are famous for their stable and reliable performance and excellent absorption and elution ability. Learn more

    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?
