COVID Swab test : How can I do a Swab Test

Posted on 2022年2月17日2022年3月22日 by Dr. Lee

From last year to now, the epidemic has changed our way of life. Working from home, quarantine, temporary unemployment, children taking early leave or schooling at home, and less seeing family, friends, and colleagues, many changes require us to adapt.

Since late December 2021, the epidemic in Hong Kong has worsened sharply after the Chinese New Year. On February 5, Hong Kong recorded 300 new positive test cases every day, setting an epidemic record; two days later, the number rose to 607; it exceeded 1,000 for the first time on February 9, and exceeded 2,000 on the 14th.

In the face of the pneumonia epidemic of new coronavirus infection, how should we conduct swab tests? How can we do personal protection in our daily life?

The new coronavirus is transmitted through the respiratory tract, and the pharynx is the place where such viruses gather more. Throat swab samples are medical cotton swabs, which are dipped in a small number of secretions from the pharynx of the human body, and the samples taken are throat swab samples. the virus type.

How can I do a swab test?

Cell medical (Dongguan) Co., Ltd., a professional VTM kits and swabs manufacturer, disposable swab tubes exporter, has many years of experience in medical application molding and flocking treatment heads and swabs.

When performing a swab test, we make the following recommendations to the sampler:

Residents are encouraged to blow their noses to clear their nasal passages.
If residents cannot perform this task, wipe their nostrils with a flocked swab or tissue.
The Resident’s name, date of birth and time of collection are affixed to the vial.
hand hygiene. Wear a mask, goggles and gloves.
With the head in a neutral position, insert the dry swab from the nostril straight back (not upward) along the base of the nasal passage until it reaches the posterior wall of the nasopharynx—usually halfway from the corner of the nose to the front of the ear (about 4~4~ 6 cm or 1.6-2.5 inches).
Gently swirl the flocked sampling swab and let it sit for a few seconds.
Carefully remove the flocked swab without touching the sides of the nostrils.
Open the virus sampling tube (VTM Tube) and place the swab in the transport medium.
Break the flocked swab along with the swab Breakpoint and close the cap.
Place the sample (viral sampling tube) in the inner bag of the plastic biohazard bag.
Remove gloves for hand hygiene; remove masks for mouth hygiene.
Complete the application form and place it in the small outer bag of the plastic biohazard bag.
Place the entire plastic biohazard bag in a separate clean paper or ziplock bag.
Refrigerated specimens.
shipped to the laboratory.

How can we do personal protection in our daily life?

1. Wash your hands frequently and maintain good respiratory hygiene.

Wash your hands under running water with soap or hand sanitiser.
Practice good respiratory hygiene. Cover your mouth and nose with a tissue or towel when coughing or sneezing, wash your hands after coughing or sneezing, and avoid touching your eyes, nose or mouth with your hands.

2. Enhance physical fitness and immunity, keep the environment clean and ventilated.

Enhance physical fitness and immunity, eat a balanced diet, exercise moderately, work and rest regularly, and avoid excessive fatigue.
Open windows for ventilation no less than 3 times a day, 20 to 30 minutes each time.

3. Minimize activities in crowded places and pay attention to symptoms.

Minimize activities in crowded places and avoid contact with patients with respiratory infections.
If you have respiratory symptoms such as cough, runny nose, and fever, you should isolate and rest at home, and seek medical attention as soon as possible if the fever persists or the symptoms worsen.

4. The role of handwashing in preventing respiratory tract-borne diseases.

Proper handwashing is one of the most effective measures to prevent diarrhea and respiratory infections. The Chinese Center for Disease Control and Prevention, the World Health Organization, and other authorities recommend washing hands with soap and water (water).

5. What should I do if there is no clean water outside the trip and it is inconvenient to wash hands?

You can clean your hands with alcohol-based sanitisers. Coronaviruses are not acid and alkali resistant and are sensitive to organic solvents and disinfectants. 75% alcohol can inactivate viruses, so a certain concentration of alcohol disinfection products can be used as an alternative to soap and running water for handwashing.

Do a good job of COVID-19 nucleic acid swab testing, maintain a healthy lifestyle, and do personal hygiene. During the epidemic, follow the principles of going out less, wearing masks, washing hands frequently, actively isolating, and maintaining personal and home hygiene.

Does the Nasal Swab Hurt?

Posted on 2022年2月14日2022年3月22日 by Dr. Lee

“Two and a half hours ago, I had a covid test, twice in one nostril, and my nose still hurts and feels weird.”

Brain Scraper: Does the Nasal Swab Hurt?

Nasal swab and throat swab which is painful? Nucleic acid testing generally takes nasal swabs and throat swabs, and the sampling methods of these two are also different.

Does nasal swab test hurt?

A nurse is doing a swab test on a patient

The nasopharyngeal swab test does not produce painful symptoms, and some patients experience discomfort. This inspection is to use a medical flocked swab to enter the nasopharynx to take a small number of secretions and send them for inspection. The pathogenic bacteria can be isolated through bacterial culture. During the operation, the patient will experience mild nausea and discomfort, which is generally within the tolerable range. During the operation, the medical staff is gentle and skilled, so there will be no pain.

Activates unconscious, instinctive reflexes. Depending on the intensity of the body’s response, discomfort, tearing, pain, and other reactions can result. Some people gag, cough, sneeze – it’s all part of the same reflex. For people who are more prone to headaches, this can cause intense discomfort.

Swab testing generally takes nasal swabs and throat swabs, and the sampling methods of these two are also different.

A nasal swab refers to a swab deep from the nasal cavity, all the way to the nasopharynx, and the secretion is taken for smearing.

Throat swabs are taken directly from the posterior pharyngeal wall of the oral cavity and the tonsillar fossa by opening the mouth. Nasal swabs are generally slightly more painful than throat swabs because they need to be passed through the nasal cavity. If there are structural abnormalities in the nasal cavity, such as a deviated nasal septum or hypertrophy of the turbinate, or there is hyperplasia in the nasal cavity, such as nasal polyps or the operator does not know much about the anatomical structure of the nose, it is possible that a cotton swab may not easily reach the nasopharynx through the nasal cavity. Partial or damaged nasal mucosa, causing local bleeding or pain and other discomforts.

Precautions before nasal swab testing?

1. Try to avoid eating 2 hours before the nucleic acid test to avoid vomiting;

2. During the inspection, reduce swallowing and do not do throat clearing (such as expectoration and spitting).

3. Pay attention to maintaining a distance of more than 1 meter between people and minimize conversations;

4. Do not drink beverages (including water), smoke, drink, chew gum, etc. 30 minutes before sampling;

5. The tested person should be informed Whether the collection personnel have a relevant past medical history (such as the history of nasal surgery, deviated nasal septum, blood disease, throat disease, etc.);

The person who did a few nasal swabs tells you how to do it without pain.

I’ve done nasal swabs several times and it’s been painless every time. Much more comfortable than a throat swab. I see a lot of netizens saying that the nasal swab is very painful and sour, this is because your posture is not correct! !!

Looking at this schematic diagram, in fact, no matter the nasal swab or the throat swab, their purpose is to let the cotton swab sample from the inner wall of the throat. Nasal swabs are not meant to poke your heavenly lid!

Therefore, you should tilt your head as far back as possible to allow the flocked swab to go in horizontally. That way the only thing you feel is a little bit of cold, and it’s over in less than 5 seconds. But if you keep your head upright, the cotton swab can only be stabbed from the bottom to the top, which will definitely stab the upper part of the nasal cavity. That position is very sensitive, and it hurts when stabbed. And because the doctor can’t see the location, he can only stir in it by the feel of the hand, so you will be sour to tears.

Nylon Flocked Swabs

Posted on 2022年2月9日2022年3月22日 by Dr. Lee

During an outbreak, everyone should be familiar with sampling swabs. When doing nucleic acid, touching the nose and throat is directly touching the sampling site of human organs, that is, directly touching our human organs. Therefore, the material of the sampling head will affect our comfort and is closely related to the subsequent detection.

On This Page

What is a Nylon flocked swab?

About sampling swab material.

What are the types of swab tests?

Nylon flock swab

Sampling swabs should be polyester, nylon and other non-cotton, non-calcium alginate swabs, and the handle should be non-wood. The breakpoint is located about 3cm from the top of the swab head, which is easy to break.

NASAL FLOCKED SWAB

Moreover, the experimental analysis shows that the extraction efficiency of nylon flocked swabs is the highest. In contrast, the recovery efficiency of nylon flocking swabs is also higher than that of other material swabs.

Nylon fibre flocking technology. The front end is coated with vertically fixed nylon short fibers, so that the entire sampling area of the sampling swab has no absorption holes, and the sampling sample will not be scattered in the fibers, which is conducive to faster and more efficient sampling!

Compared with traditional winding swabs, nylon flocking swabs collect and release 3 times the number of samples, do not damage cell samples, ensure the survival rate of cell samples, do not leave fatty acids, do not affect the test and detection results, not to mention Said to cause harm to the human body.

What materials cannot be used for sampling swabs?

As we all know, the materials of medical swabs have always attracted much attention. After all, medical swabs come into direct contact with the skin. People who touch the skin can first touch alcohol for disinfection, that’s fine, but what about those who have direct contact with organs? For example, the throat swab we are most familiar with during the epidemic.

The throat swab is in direct contact with the sampling site, and the material of the sampling head is closely related to subsequent testing. The sampling swab head should be made of nylon flocked swabs or rayon, and calcium alginate sponges or wooden stick swabs (including bamboo sticks) should not be used.

Cotton products should not be used for the swab head, because the cotton fiber has strong adsorption to protein and is not easy to clean into the subsequent storage solution; wooden.

What are the types of swab tests?

There are two different types of COVID tests – Swab tests and antibody tests.

1. Swab tests can show if you have an active coronavirus infection and should take steps to isolate or isolate yourself from others. There are currently two types of diagnostic tests – molecular (RT-PCR) tests that detect the genetic material of the virus, and antigenic tests that detect specific proteins on the surface of the virus. Samples are usually collected with a nasal or throat swab, or saliva spits into a test tube.

2. Antibody tests look for antibodies that the immune system produces in response to a threat, such as a specific virus. Antibodies can help fight infection. Antibodies can take days or weeks to develop after infection and may remain in the blood for several weeks after recovery.

Therefore, antibody tests should not be used to diagnose active coronavirus infection.

Right now, researchers don’t know whether the presence of antibodies means you’ll be immune to the coronavirus in the future. While there is a lot of uncertainty surrounding this new virus, the widespread availability of antibody testing and clinical follow-up over time also has the potential to provide the medical community with more information about whether and how long a person has recovered from the virus of people have a reduced risk of infection if they are re-exposed to the virus. Learn more about antibody testing.

The Mission of A Virus Test Swab

Posted on 2022年1月25日2022年3月22日 by Dr. Lee

The Mission of A Virus Test Swab

From the sampling point to the testing room, then to the temporary storage point of medical waste.

Then to the hazardous waste centre, to the power plant, and finally to the soil.

A swab for nucleic acid detection completed the task and became a piece of pollution-free ash and fill it in the soil.

At present, we are in a critical period of anti-epidemic.

An ordinary hospital has a maximum of 11,220 samples per day at a single sampling point.

The Mission of A Virus Test Swab

At nine o’clock in the morning, at the nucleic acid testing and sampling service point, citizens who were ready to test lined up.

Everyone wears a mask and consciously separates one meter from each other.

At the beginning of the inspection window, the heavily armed nurses washed their hands with an antiseptic solution.

And then removed a flocked swab about 15 cm long from the packaging bag to take a sample before taking the throat swab.

The nurse opened the collector’s mouth wide, and she skillfully inserted the flocked swab into her pharynx.

Then picked up a sampling tube (virus transport medium) with her left hand. And inserted the collection stick into the sampling tube with her right.

With a little force, the tip of the cotton swab breaks enters the sampling tube, seals it. And throws the long stick into the yellow medical waste bin.

As a testing point for ordinary citizens and inpatients, as an ordinary citizen and inpatients, the use of cotton swabs in an ordinary hospital reached 11,220.

Medical waste treatment forms closed-loop management in nucleic acid testing laboratories.

Take the flocked swab, put the swab head into the sampling tube, and paste a barcode similar to “ID card”. And carefully seal it, put it into a transparent sealed box.

And then send it to the transfer cabin of the PCR laboratory of the Department of Infectious Diseases by staff wearing protective clothing.

The PCR laboratory is under negative pressure, and after the virus enters, it cannot come out. After the outbreak, the PCR laboratory strictly abides by the medical waste treatment process, forming closed-loop management of the laboratory.

An hour later, staff in protective suits transported medical waste out of the ward in sealed yellow bags and sealed with “extremely infectious waste”.

Then, the workers send these medical wastes by trolleys to the medical waste temporary storage area at the nucleic acid collection point 100 meters away. For the medical wastes for nucleic acid testing, he transports an average of about 35 kilograms per day.

We need to place the virus sampling tube for 48 hours during the transfer process

Except for professionals, our PCR laboratory does not allow patients and the public to enter here.

To ensure safety, all medical waste from nucleic acid testing collection points, including swab sticks, is kept here for 48 hours.

After our test results come out and are confirmed to be correct, they will be sent to the hazardous waste treatment centre by a medical waste transfer vehicle.

At ten o’clock in the morning, the staff of the hazardous waste centre arrived at the scene. Unload the empty shipping box and load the ship with medical waste that has been sitting for 48 hours.

The sampling flocked swabs used must be incinerated at high temperatures above 1100°C.

There are two buildings, an incineration workshop and a cooking room, in the yard of the Hazardous Waste Center.

The staff in protective suits skillfully unload boxes of medical waste from the transfer vehicle and load boxes of hazardous waste into bucket elevators.

What is Pooled Sample Test?

Posted on 2022年1月20日2022年1月20日 by Dr. Lee

Pooled Sample Test?

With the 2019 coronavirus disease (COVID-19) pandemic, doing a good job in viral nucleic acid detection is the top priority. However, detection of the virus is still limited due to resource constraints. Pooled sample testing offers a way to significantly improve testing power.

“mixed nucleic acid test” or “Pooled Sample Test”, referred to as “mixed test”.

Which means that two or more samples are mixed and tested. method for positive samples.

What is the difference between the “mixed collection” of community nucleic acid testing and the “single collection” of the hospital?

Why do community streets adopt the mixed mining model?

Under what circumstances should I test individually?

What is pooled COVID testing?

The so-called “mixed detection” of nucleic acid.

Takes throat swab samples from multiple people and puts them together for viral nucleic acid detection.

Pooled Sample Test VTM Kits

In fact, Medical use of Pooled Samples is common.

In blood collection systems such as apheresis stations.

We use pooled samples to detect the presence of infectious disease antigens and antibodies in pooled samples of multiple people.

There are two modes of “mixed detection”. One is to sample several people, such as 3 or 5 people and put them into the same sampling tube.

The other is to mix samples of the same volume from 3 or 5 people during laboratory testing, also known as “sample mixing”.

From a scientific point of view, the first “mixed sampling” mode will not affect the sensitivity of nucleic acid detection. While the latter mode of mixed detection of samples has a certain impact on the sensitivity of the detection, the degree of impact is controllable.

In order to detect high-risk groups, such as symptomatic patients and close contacts in fever clinics, we still recommend separate sampling.

For screening of low-risk groups, pooled sample test is our first choice.

Is the mixed detection technology reliable?

Is the “five-in-one” and “ten-in-one” mixed mining detection technology reliable?

“The size of the single-collection tube and the mixed-collection tube are different, and the amount of the preservation solution is also different.

Based on the results of a large number of basic experimental research and practical operations in the previous period.

The increase in the volume of the mixed-collection preservation solution has no effect on the detection results of weakly positive specimens.”

In the case of an extremely low positive rate, the 10-in-1 mixed detection technology is very efficient.

The FDA is aware that there is a great interest in performing testing using pooled samples.

This approach increases the number of individuals who can be tested with the same amount of resources.

What are the benefits of mixed nucleic acid detection?

The hybrid detection of nucleic acid has greatly improved the nucleic acid detection capability, reduced the burden of personal testing costs, and did not affect the time for issuing the test report.

The testing time of a single test and mixed test laboratory is the same, but compared with a single test, the mixed test is more suitable for mass and group screening.

In the case of small-scale outbreaks, the use of mixed detection can improve efficiency, play the role of multiple screening, early diagnosis, reduce transmission, and save social costs.

Whether the population is suitable for mixed testing shall be carried out in accordance with the requirements of the provincial and municipal epidemic prevention and control headquarters,

The medical institutions carrying out the testing must follow the technical requirements and standards of the municipal health department.

Which groups recommend the single purchase and single inspection?

It is worth mentioning that single sampling and single inspection are recommended for specific populations.

The above notice specifically mentioned that COVID-19 nucleic acid 10 in 1 and 5 in one mixed detection technology is suitable for large-scale rapid screening of the low-risk populations, and is more suitable when the overall positive rate of population is low (0.1%).

However, for the detection of high-risk groups such as symptomatic patients, close contacts and people in key areas in fever clinics.

Recommended to adopt single sampling and single detection.

What should I pay attention to when doing pooled sample detection?

1. When going to the testing point for nucleic acid testing, wear a mask, and it is best to prepare one or two spare masks.

2. Two hours before the swab test, it is recommended not to eat to avoid vomiting during the test.

3. When waiting for the test, remember to keep a distance of more than one meter between the front and rear personnel to avoid close contact.

4. Whether it is doing swab testing or getting the report, it needs to be certified as one, so be sure to bring ID cards, receipts and other materials, so as to avoid incomplete materials at that time, which will affect the testing and reporting.

How to Swab For Covid Test

Posted on 2022年1月15日2022年3月22日 by Dr. Lee

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.

The doctor is testing the patient’s nasopharynx swab

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.

Pcr test nasal swab and an antigen test difference for covid 19

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.

Flocked Tip Swab Nylon Sterile Nasal Swab Stick

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:PCR swab test,antibody test, and antigen test difference

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.

Anal swab

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.

Covid Mouth Swab Test

Posted on 2022年1月12日2022年3月22日 by Dr. Lee

Covid Mouth Swab Test

Three key points for oral swab collection!

The oral swab is an all-in-one system that can collect, stabilize, transport and purify DNA from saliva in advance, providing a painless and risk-free new way to collect microbial DNA for disease control and prevention.

Accidentally, it is easy to cause people to be infected with the new coronavirus, and the surface detection is not sensitive, and the operation is easy to lead to standardized operation.

Awareness Check Tool:

Testing equipment for testing equipment, including testing tools for testing equipment, testing equipment for testing equipment, testing equipment for testing equipment, including safety testing equipment.

Virus Sampling Tube & Nasopharyngeal Swab (Inactivated)

Oropharyngeal sampling points:

1. Sufficient light: Good lighting should be provided for both indoor and outdoor light sources. If necessary, flashlight lighting should also be provided.

2. Full exposure: The three anatomical locations for oropharyngeal swab collection must be completely exposed, and a spatula should be used when exposing bilateral tonsils.

3. Accurate location: The oropharyngeal swab should not touch other parts, such as the tongue, chin, etc., except for the three designated locations, so as not to be stained with saliva and affect the quality of specimen collection.

Covid Mouth Swab Test Pre-harvest preparation

Routine screening:

Work clothes, medical protective face shield, work cap, gloves, isolation gown, goggles (anti-fog) or face shield.

Influenza or suspected cases:

Wear work clothes, medical protective masks, work caps, gloves, isolation gowns or protective clothing, goggles (anti-fog) or protective face shields, and add shoe covers or boot covers if necessary.

Order of protective clothing:

Work caps that do not need to be worn. → Protective masks (Wearable head-mounted type and a tightness test should be performed after wearing them.)→ No shoes protective clothing (Boot covers should be added instead of foot protective clothing.) → Surgical gloves. → Protective screen or goggles.

Employee Registration Protection:

Tooling or isolation gown. → Medical-surgical mask or medical protective face shield. → Disposable work cap.

Protective clothing should be replaced every 4 hours and should be replaced in time if there is moisture or pollution.

Supplies preparation: Throat swab sampling sleeve, tongue depressor, inspection sheet and barcode, transport bag or refrigerator, 75% alcohol, pen.

Nucleic acid collection

1. We asked the examinee to tilt his head slightly, open his mouth.

And lift the upper jaw vertically to expose the posterior pharyngeal wall.

2. Use the front end of a sterile long cotton swab to quickly rub up and down 3-5 times on the bilateral pharyngeal tonsils.

And 3-5 times on the upper and lower sides of the posterior pharyngeal wall.

3. After scraping, open the sampling tube. Insert the front end of the sample vertically into the sampling tube. Insert the sampling tube. Break the sampling tube to expose the outer part of the tube. And tighten the cap.

Place the sampling tube in a biosafety sealed bag, mark the name and other information on the sampling tube, and complete the sampling.

Notice:

1. When sampling with the Covid Mouth Swab Test, it is best not to call “ah”, because once the sampled person is a positive patient, he will shout “ah”, exhale the virus in large quantities, and form aerosols in the sampling area.

When sampling, we advise patients to open their mouths and not yell or take deep breaths.

2. During the sampling process, one person collects and one person disinfects.

When the sampler holds the cotton swab, try to take it as far as possible.

3. A large number of samplers collect oropharyngeal swabs face-to-face with the sampled person.

Therefore, during the sampling process, the breath exhaled by the patient can easily and directly pose a great threat to the medical staff.

To reduce the risk of the sampler, we recommend that healthcare workers sample at a 45-60 degree angle to reduce risk.

End of Swab Test sampling

1. Spray and disinfect the generated medical waste layer by layer, and tie the gooseneck double medicine bag tightly to ensure that the seal is tight, has no damage, and has no leakage. Do not squeeze the contents of the medical waste bag. Annotation generates point information.

2. The order of unprotected items: hand hygiene → take off the protective face shield or goggles → hand hygiene → take off the protective clothing (take off the boot cover together) → hand hygiene, take off gloves, hand hygiene → take off the protective mask and Disposable work cap → hand hygiene.

Nasopharyngeal Swab Sample

Posted on 2022年1月7日2022年3月22日 by Dr. Lee

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?

how to collect swab sample

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.

flocked swab

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.
