Covid Test Throat Swab

Covid Test Throat Swab

There is more than one sampling method to detect covid-19. Everyone should have heard of the nasopharyngeal swab test and oropharyngeal swab. Can you do it yourself? Or does it have to be done by a professional for you?

In this article you will learn:

What difference is between a nasal swab and a throat swab COVID-19 test?

The main steps to take the Covid Test Throat Swab test.

Which COVID test is more accurate, nasal or throat swab?

 

What difference is between a nasal swab and a throat swab COVID-19 test?

Swab Test

Swab Test

Sampling methods and location are different.

The accuracy rates of nucleic acid detection nasal swabs and throat swabs are usually similar, and the main difference lies in the sampling method and sampling site.

For nasal swabs, nasopharyngeal flocking swabs are mainly used to test the secretions from the inside of the nasal cavity and the surface of the nasal mucosa through the nasal cavity; In contrast, throat swabs are obtained by dipping pharyngeal specimens through the oral cavity. Tests are conducted to determine if the sampler is infected with the new coronavirus.

There are several different ways to test for COVID-19:

Testing for COVID-19 falls into two main categories:

1. Diagnostic test/diagnostic test: to detect whether you are currently infected with SARS-CoV-2 virus, also called viral swab test.

2. Antibody test/antibody test: It is used to detect whether you have been infected with the SARS-CoV-2 virus, and cannot be used to diagnose whether you are currently infected.

Polymerase chain reaction (PCR) swab test

  • Nasal Swab A nasal swab is a method of examining the nasal passages to see if there is a bacterial or viral infection. The nasal swab is something similar to a sterile flocked swab, which is used for the collection of nasal specimens.
  • Throat swab, also known as “oropharyngeal swab“, refers to using a sterilized medical long cotton swab to wipe a small number of secretions from the throat of the person to be tested, and then perform respiratory virus testing. A sample is taken from the back of the throat through the mouth.
  • Nasopharyngeal swabs are actually relatively long nasopharyngeal flocked swabs, similar to longer sterilized cotton swabs.
  • Its main function is to take nasopharyngeal secretions for bacterial culture and drug sensitivity tests. Go deep into the nose and collect a sample from the back of the nose or the back of the throat.
  • Saliva swabs use a saliva sample to test for the COVID-19 virus. This is usually done by swabbing the oral area, such as the cheeks.

The rapid antigen tests that most people use in the U.S. and elsewhere are designed specifically for nasal swabs.

The main steps to take the Covid Test Throat Swab test.

Specimen collection crowd:

1. Patients with suspected pneumonia and suspected cluster cases of new coronavirus infection;

2. Others who need to be diagnosed or differentially diagnosed with new coronavirus infection;

3. Those returning to the city/returning to work without obvious symptoms (fever, respiratory symptoms) .

Before swab test sampling:

Preparation before throat swab: throat swab sampling tube (tube + swab), sealing bag with a size suitable for displaying the general biological hazard sign, tongue depressor, etc.

Check the label on the outside of the throat swab (whether there is a date, specification, whether the colour of the sampling liquid has deteriorated, whether it is turbid, whether there is sediment, etc., and also improve the information of the sampling tube, such as name, sampling unit, and paste the sampling number);

It is necessary to communicate with the examinee first, and inform the examinee in advance not to smoke, drink, or eat chewing gum or irritating or savoury food within 30 minutes before sampling.

If your test needs to try:

The swab crossed the base of the tongue and reached the pharyngeal stenosis, and quickly wiped the palatine arches and pharynx and tonsil secretions on both sides.
Drop the swab into the virus delivery medium, assist the cap to break the swab stem so that it is fully seated in the tube.
Tighten the cap of the tube, mark it well, put it in a plastic bag and seal it.
Submit the specimen for inspection in a timely manner.

Which COVID test is more accurate, nasal or throat swab?

Research is underway to determine the most accurate way to test for COVID-19, specifically using the Omicron variant. We do know that Omicron tends to stay in the upper airways rather than travel to the lower airways or lungs. Therefore, a throat swab may be more likely to find it. But again, research is still ongoing.

A recently published study suggests that saliva swabs may be more accurate in detecting Omicron variants than nasal swabs. But the study looked at PCR tests, not at-home rapid tests. So the results may not apply to home tests because these tests work differently. Another study found that PCR throat swabs were slightly better at detecting the virus than nasal swabs. But this research was done before the Omicron variant.

It is also important to note that throat swabs are more difficult to collect. If done incorrectly, the results may be inaccurate. At this point, it is best to wait until we have more data and leave the throat swab to the provider.

Notice

For the Omicron variant, a saliva test (and possibly a throat swab) may be more accurate than a nasal swab. But current rapid home tests are not designed for throat swabs. To avoid potentially false results, these tests should only be used as intended. Until we do more research, we can’t say for sure whether combining swabs with home testing is a good idea. When in doubt, consider a PCR test for more accurate results.

Nasopharyngeal Swab Pcr Test

There are two broad categories of COVID-19 tests: viral diagnostic tests (which detect an active COVID-19 infection) and antibody tests (which detect past COVID-19 infections).

The PCR swab test is a qualitative oropharyngeal or nasopharyngeal collection used to detect the novel coronavirus, the virus that causes COVID-19. This test helps determine if you have been exposed to the virus. The COVID-19 PCR test is a molecular test that detects the genetic material of the virus.

The current more accurate test for COVID-19 is to use RT-PCR to assess the presence of SAR-CoV-2 RNA in collected samples. If anything, the subject was almost certainly infected with the virus.

What are the diagnostic tests for the COVID-19 virus?

With the development of testing for COVID-19, there are now four main forms of diagnostic testing for the virus:

Nasal Swab Test: A test involving a shallow nasal flocked swab.

Cell medical flcoekd swab

Cell medical flcoekd swab

Nasopharyngeal test: A test that involves a deeper nasal swab using PCR technology.

Saliva Test: A test involving a saliva sample and PCR technology.

Oral swab test: An innovation in COVID-19 testing that allows anyone to test quickly, non-invasively and easily. Use PCR technology.

The COVID nasal swab test, also known as the nasal swab test, is a medical test used to detect viruses in the nose that can cause respiratory infections.

 

How does Nasopharyngeal Swab detect coronavirus?

Nasopharyngeal testing collects a sample from the back wall of the nasopharynx.

(1) Measure the distance from the nostril to the base of the ear with a swab and mark it with your finger.

(2) Let the patient’s head relax naturally, put the swab against the nostril wall and slowly rotate it into the patient’s first nostril to the nose and palate, and then slowly take it out while wiping. With the same swab, leave the swab in the nose for 15-30 seconds, then gently swirl 3 times. Wipe the other nostril in the same way;

(3) Put the flocked swab into the virus delivery medium, break the swab rod, and place it completely in the tube.

(4) Tighten the cap of the tube, make a mark, put it in a plastic bag and seal it

(5) If it is necessary to collect from both nostrils, a swab should be used separately.

(6) Store at 4°C (short-term storage).

What types of nasal swab sampling are available?

There are three types of sampling swabs used in the nasal cavity, namely nasopharyngeal swabs, nasal cavity swabs, and middle turbinate swabs.

nose structure

nose structure

Nasopharyngeal testing collects a sample from the back wall of the nasopharynx.

Sampling from the middle turbinate location is not as uncomfortable as the nasopharynx.

Anterior nasal swab/nasal swab:

Taking a sample in the anterior position of the nose does not cause discomfort and can be used by people with narrow nasal passages.
The sampling difficulty is low, and the patient can easily complete the anterior nose sampling by himself.

Although nasopharyngeal swabs, nasal swabs and turbinate swabs have different sampling methods, they can all be used to collect samples and then use PCR results to determine whether the owner of the sample has been infected with the new coronary pneumonia virus.

Do you feel any discomfort? Does it hurt!

Nasopharyngeal Swab Sample

Nasopharyngeal Swab Sample

Nasal swabs and throat swabs are the two most widely used sampling methods. Just use a flocked swab to gently wipe the throat mucosa or nasal mucosa, and it can be completed in 1 to 2 seconds, which is generally not uncomfortable. However, for some more sensitive people, irritating retching, nausea or choking may occur. At this time, it is best to use a tissue to cover the mouth and nose and try to hold it back to avoid vomit or sputum. create pollution.

How does nucleic acid testing relieve the discomfort of sampling?

Both nasopharyngeal swab sampling and oropharyngeal swab sampling will make the sampled person feel slightly uncomfortable, which can be relieved after a short rest. Therefore, during the sampling process, the sampled person should cooperate with the sampling personnel as much as possible, relax as much as possible, and do not move the head excessively to avoid scratching the mucous membrane with the sampling swab.

Is the nasal swab COVID test the best test?

What are the current testing methods for COVID-19?

There are two types of virus detection:

  • Nucleic acid amplification test (NAAT) (PCR test) and antigen test.
  • Antibody tests (also called serology tests) can show whether you have been infected in the past.

Mouth Swab vs Nasal Swab

HOW TO USE

HOW TO USE

Nasal swabs generally enter from the nasal cavity and take the secretions at the back of the nasopharynx, while pharyngeal swabs enter from the mouth to the throat and take local secretions for inspection, that is, the two enter in different ways.

It is not a single product, but a set consisting of a sampling flocked swab, Viral Transport Medium and a plastic tube. Sampling process: use a swab to sample the patient, but the preservation solution into a plastic tube, put the sample into the plastic tube preservation solution, and transport the preserved sample to the laboratory for testing.

Special instructions for virus sampling tubes:

If the collected sample is used to detect viral nucleic acid, it must be used with a nucleic acid extraction kit and nucleic acid detection reagent; if it is used for virus isolation, it must be combined with a cell culture medium.

Different application fields have different requirements on the volume of sampling liquid, please replace the corresponding product according to the prompts in the sequence information:

Viral sampling tubes that collect viral samples from clinical patients generally require less fluid.

For a collection of single-use virus sampling tubes and short-term delivery of influenza virus from the external environment. We typically require a liquid volume of 3 to 6 ml.

Virus sampling tubes have three requirements, including transport, storage, and sample usefulness.

Transportation, ensure that the samples do not leak during transportation;

Preservation, ensure that the sample does not leak during the preservation process;

In terms of the usefulness of the sample, the sampling tube itself does not have a toxic effect on the sample, so as not to affect the material collected in the sampling tube, which in turn affects the test results.

COVID Swab test

COVID Swab test : How can I do a Swab Test

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:

  1. 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.
  2. The Resident’s name, date of birth and time of collection are affixed to the vial.
  3. hand hygiene. Wear a mask, goggles and gloves.
  4. 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).
  5. Gently swirl the flocked sampling swab and let it sit for a few seconds.
  6. Carefully remove the flocked swab without touching the sides of the nostrils.
  7. Open the virus sampling tube (VTM Tube) and place the swab in the transport medium.
  8. Break the flocked swab along with the swab Breakpoint and close the cap.
  9. Place the sample (viral sampling tube) in the inner bag of the plastic biohazard bag.
  10. Remove gloves for hand hygiene; remove masks for mouth hygiene.
  11. Complete the application form and place it in the small outer bag of the plastic biohazard bag.
  12. Place the entire plastic biohazard bag in a separate clean paper or ziplock bag.
  13. Refrigerated specimens.
  14. 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.

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.

Nasal swab and throat swab which is painful?

Which is more accurate between nasal swab and throat swab? Essentially, if the operation is standardized, there is basically no difference between the two sampling methods, but we usually eat and drink water, etc., which will reduce the virus accumulation in the oropharynx to a certain extent. , In practice, the positive detection rate of nasal swabs is slightly higher than that of throat swabs. In general, oropharyngeal swabs are suitable for most people and are convenient and fast, while nasopharyngeal swabs are slightly more accurate, but the human body does not feel comfortable.

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

Nylon Flocked Swabs

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.

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

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.
