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.

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.

1. Sampling is more comfortable and convenient.

Our company uses the existing technology “spraying technology” to vertically attach millions of nylon flocked micro fibers to the head of medical grade handle through the flocking process of electrostatic charge. The function of vertical nylon fiber is similar to that of 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 thickness to make the softness different.

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

Sterile Flocked Nylon Swab with 80mm Breakpoint.

2. Flocking swab samples release more.

The capillary action between nylon fiber bundles promotes the strong hydraulic absorption of liquid samples. The sample remains on the surface to make elution easier. In the traditional cotton swab, most of the samples collected are still captured in the fiber matrix of the head, which is not easy to release or the release amount is small. Flocked swabs have been shown to release up to 95% of the sample, compared with 25% for standard fiber pointed swabs. If the sample size is particularly small, the use of flocking swabs is particularly important.

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

In order to limit the damage to the sample and improve the accuracy of detection, disposable sampling swab is made of better quality nylon flocking swab.

This makes flocking swabs an ideal choice for PCR Swab Test. Therefore, for scientists using PCR technology, the new flocking swab is PCR compatible and does not contain RNase and DNase.

Oral Swab Stick-Oropharyngeal sampling swab.

COVID-19 Oral Swab test is an important reference for diagnosis and evaluation of curative effect of new crown pneumonia.

Nucleic acid screening samples mainly come from deep cough sputum or pharyngeal swabs.

Pharyngeal swabs include nasopharyngeal swabs and oropharyngeal swabs.

The results of COVID-19 nucleic acid test are also useful.

What is the key to the collection of nucleic acid test specimens from pharyngeal swabs?

Whether collecting nasopharyngeal swabs or oropharyngeal swabs, the collection depth is the key.

For example, if the nasopharyngeal swabs are not collected deep in the nasal cavity, most of the cells that may be collected are virus-free cells, which may cause “false negative”.

What is the difference between Oral Swab Stick and Nasal Swab?

Pharyngeal division includes nasopharynx, oropharynx and laryngopharynx. The mucosa of the three is continuous and belongs to the area of upper respiratory tract. The sampling path of nasopharyngeal swab and oropharyngeal swab is different. Oral sampling is oropharyngeal swab and nasal sampling is nasopharyngeal swab.

What are the advantages of nasopharyngeal swabs?

It can stay in the pharynx for a long time in order to obtain more sufficient specimens; The exposure risk of the sampler is lower than that of the oropharyngeal swab, because the sampler can stand behind the patient’s side during sampling, and the patient is required to pull down the mask to expose only the nostrils and cover the mouth without looking directly at the patient’s mouth, and there is basically no pharyngeal reflex. A few patients may have sneezing reflex after sampling, and the patient can be covered with elbows or paper towels, And because the sampler is not directly in front of the patient, the exposure risk is quite low, so the psychological pressure of the sampler will not be so great.

Can a positive oral swab stick confirm COVID-19?

The novel coronavirus novel coronavirus infection can be diagnosed by the new swab positive guide for new coronavirus infection, but it does not necessarily indicate pneumonia.

After infection with COVID-19, the old person may show two different infections, including fever, dry cough, weakness, and asymptomatic infection.

Patients with positive nucleic acid test of new crown must be isolated and treated.

Only when nucleic acid is negative for more than 24 hours, body temperature is normal and pneumonia symptoms disappear can isolation be lifted according to the situation.

How to sample oropharyngeal swabs?

First collect the oropharynx, gently and repeatedly wipe it for more than 3 times, and then collect the depth of the throat wall for more than 3 times.

The whole process takes about a few seconds. It may be a little disgusting, but there won’t be too many reactions. It’s more acceptable.

According to the personal experience of colleagues: slightly disgusting, but completely acceptable

The site experienced the collection of oropharyngeal swabs. The whole sampling process is only a few seconds and there is almost no discomfort.

How to Obtain a Nasopharyngeal Swab Specimen

As a non-invasive operation, nasopharyngeal swab sampling is the first choice for diagnosis, monitoring and differential diagnosis of New Coronavirus pneumonia. Its sampling randomness is high. However, the sampling personnel may have false-negative test results due to the different location, strength and time of scraping samples, which may have an adverse impact on the epidemic prevention and control. During the operation, the patient choked and splashed to produce an aerosol, which is very easy for medical staff to have occupational exposure.

This paper mainly explains in detail the protection of medical staff when collecting nasopharyngeal swabs, the collection, packaging and transportation of nasopharyngeal swabs, as well as the patient’s body position, operation methods, collection parts and precautions during specimen collection.

Effective communication and nurse-patient cooperation help the successful collection of nasopharyngeal swabs.

Before the operation, the degree of cooperation of patients should be effectively evaluated. Inform the patient of the collection purpose and precautions in advance.

Clinicians should be cautious if the patient has recent nasal trauma or surgery, a significant deviation of the nasal septum, or a history of chronic obstructive nasal patency or severe coagulation disease.

Standard protection is the foundation of successful nasopharyngeal swab collection

Operator preparation: first, wear protective clothing, wash hands with soap and water (or alcohol), and wear a pair of non-sterile gloves. Then, according to the recommendations of the Centers for Disease Control and prevention, wear an N95 or higher protective mask. Finally, wear a face mask to protect your face and eyes.

Swab Nasal Covid Sampling preparation: operating platform; Sampling materials, including nasopharyngeal test swab, VTM kits, inspection sheet and bar code, transport bag and hand disinfectant, to ensure the sterilization effect and validity period.

(2) Measure the distance from nostril to ear root with a swab and mark with your fingers.

(3) Insert the swab into the nostril in the direction perpendicular to the nose (face) until the finger touches the nose, keep the swab in the nose for 15-30 seconds, and then rotate it gently for 3 times.

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

(5) Tighten the tube cover, mark it, put it into the specimen bag and seal it.

(6) If it is necessary to collect from two nostrils, one swab should be used respectively.

(7) Store at 4 C or on ice (short term storage).

CDC recommends that all patients suspected of infection with COVID-19 use masks.

Ask the patient to take off the mask and wipe the nose with a paper towel to remove excessive secretions from the nasal cavity.

Remove the cotton swab from the package. Tilt the patient’s head back slightly so that the nasal tract is more accessible.

Let the patient close his eyes to reduce the slight discomfort caused by the operation.

Gently insert the swab into the nasopharynx along the nasal septum until resistance is felt.

Tips for nasopharyngeal swab sample collection.

The nasopharynx swab is inserted quickly. Do not hesitate. Some patients are intolerant to the operation of probing the nasopharyngeal swab into the nasal cavity, resulting in tears, foreign body feeling, etc. before the operation, ask the patients to inhale deeply in order to avoid choking and coughing.

When the cotton swab reaches the expected depth, do not continue to go deep, so as not to cause nasal mucosal damage and bleeding. During the stay, use finger strokes with the patient to read the seconds. It can distract attention, eliminate tension and motivate patients to ensure successful collection.

Never allow the patient to fully raise his head and bend the swab, which will lead to incorrect retention position of nasopharyngeal swab head and ultimately affect the accuracy of specimen collection results.

The operator can select the left / right side of the operator according to his left and right hands, and stand on the patient’s head and shoulder for operation. The patient’s head does not need to be biased to the opposite side. It is difficult to control the entry angle of the flocked swab when facing the side head, which may cause mucosal irritation. For patients with excessive tension, the operator can hold the patient’s hand and give comfort.

viral transport medium with swab | COVID-19 sampling and collection kits

The epidemic has disrupted the whole world and affected many industries.

During the outbreak of  COVID-19, people were paying close attention to the epidemic situation while doing personal protection. Novel coronavirus pneumonia and influenza were the most frequent period of communication in winter and spring. The most important way to control the epidemic is to select new patients with new crown pneumonia from many respiratory patients.

About viral transport medium with swab.

Swabs and virus transport media are a transport and collection system for long-term freezing, transport and collection of clinical specimens containing viruses.

The main species of organisms usually transported through this medium include chlamydia, urea plasma organisms and mycoplasma.

With the outbreak of COVID-19 pandemic, swabs and virus transport mediums were used to freeze and collect SARS-CoV-19 virus samples.

Rub a swab on the skin or vesicles to collect virus samples. The collected samples are then sent to the laboratory with transport media.

Why do swabs need virus transport media？

After virus collection, the traditional method can not be detected by PCR immediately. The virus itself will quickly dissolve in vitro and affect subsequent tests.

viral transport medium with swab -vtm kits

viral transport medium with swab -vtm kits

Purpose of virus transport media:

1. For monitoring and sampling infectious pathogenic microorganisms by disease control departments and clinical departments. It is applicable to the sampling of influenza virus (ordinary influenza, highly pathogenic avian influenza, influenza A H1N1 virus, etc.), hand, foot and mouth virus and other types of viruses.

2.For the sampling of mycoplasma, chlamydia and Ureaplasma.

3.. To transport nasopharyngeal swab samples or tissue samples at specific parts from the sampling site to the detection laboratory for PCR extraction and detection.

4.To preserve nasopharyngeal swab samples or tissue samples at specific sites for necessary cell culture.

Precautions for sample transportation.

1. Inspection time and temperature control:

After samples sampling, for inspection as soon as possible and sent to the laboratory within 2 ~ 4H as far as possible.

Transport at 2 ~ 8 ℃, and the transport time shall not exceed 72h. If it exceeds 72h, stored and transported at – 70 ℃ or lower.

2. Viral transport medium transport container:

Virus transport tube：waterproof, damage proof, leak proof, high temperature (low temperature) and high pressure resistant. 
Tube body: biological hazard signs, warnings and reminders with relevant regulations. 
Transport container: three-layer packaging system, namely inner packaging, middle packaging and outer packaging.

3. Transportation in the hospital:

The specimen delivery personnel shall be provided with secondary protection and carry 75% ethanol with them.

4. Long distance transportation:

The transport package of 2019 ncov specimens belongs to class A, and the corresponding UN number is un2814.

what is the flocked swab?

Flocked Swab Meaning

Since the outbreak of COVID-19, the word “nasopharyngeal swab” has become a high-frequency word we talk about every day.

In recent months, the new crown pneumonia epidemic broke out again in countries all over the world. It’s worrying to watch the data released by WHO every day!!!

Flocked swab material

The flocked swab is made of nylon fiber flocking technology, and the front end is coated with nylon short fiber fixed vertically so that there is no absorption hole in the sampling area of the whole sampling swab, and the sampling sample will not be dispersed and retained in the fiber, which is conducive to faster and more efficient elution.

Traditional cotton swabs can not completely collect and elute samples while flocking swabs can elute 95% of samples. Therefore, the use of flocking swabs has great advantages for various sample collection applications.

The flocked swab is to deposit nylon fibres on the surface of the medical ABS rod in a certain direction through an electrostatic field to form a brush layer.

What is the purpose of flocked swabs?

Flocking swabs are the best choice for nucleic acid detection because they can better collect cell or biological samples at the collection site and release samples quickly.

Application: forensic medicine, DNA, microorganism, virus sampling, Oral swab, nasal swab etc.

What are flocked swabs used for in COVID-19?

The autumn and winter communication season is a period of the high incidence of common cold and influenza, and the most important means to control the epidemic situation is to select real patients with new crown pneumonia from a large number of respiratory tract patients.

At present, the most effective and widely used new crown sampling methods are nasopharyngeal swab and oropharyngeal swab sampling.

Nasopharyngeal swab collection method.

1. Keep the patient’s head still and remove the secretions on the middle surface of the anterior nostril;

2. Measure the distance from the nose tip to the earlobe with a swab and mark it with your fingers. Insert the swab into the nasal cavity in the direction perpendicular to the nose (face). When encountering resistance, it reaches the posterior nasopharynx, keeps the swab in the nose for 10 ~ 15 s, rotates it gently for 3 ~ 5 times, and take out the test flocked swab.

According to the American Society of Microbiology guidelines for the submission of clinical microbial specimens, the nasopharyngeal swab should be twisted on the nasopharyngeal mucosa, retained for 10-15 seconds, and then removed.

It’s hard, and the tough guy still cries.

I have experienced both sampling methods.

It is not a painful cry, but a stress response caused by strong stimulation of the weak nasopharyngeal mucosa, with tears and tears.

Pharyngeal(oral) swab: the collection process is faster (just a few seconds) and less painful, but you may feel nausea and vomiting, and some people have no obvious reaction.

As we are in the epidemic period, we should improve our awareness of self-protection when doing nucleic acid testing.
