Oral Swab Covid Test

Posted on by

With repeated epidemics, nucleic acid testing and throat swabs seem to have become part of our lives. We also all know where to go for nucleic acid testing, but what actually happens during a swab test? What are the tests for COVID-19? If you haven’t done nucleic acid testing, you may wish to read this article first. This article will popularize five things about Oral Swab testing.

On this page, you will learn:

What are the tests for COVID-19?

Oral swabs and nasal swabs or saliva. In the experiments, oral flocked swabs were used to collect samples from the oral cavity for the oral examination.

This is different from a saliva test, which spits saliva into a small container.

COVID-19 Test, there are usually two main types of tests:

There are two main methods of nucleic acid detection: acid detection reagents and antibody detection. The first method is usually PCR detection through throat swabs, gene amplification, and then nucleic acid detection.

The antibody test is to choose blood, the method of blood draw to see the results, to observe whether the antibody titer increases.

How to do a mouth swab for COVID-19?

1. Rinse your mouth with water 30 minutes in advance (no toothpaste, especially breastfed babies need to drink a few mouthfuls of water, and no mouthwash);

2. Mark the envelope with a pen (eg: father, mother or child) and date of collection, name.

3. Hold the CellMedical flocked sampling cotton swab in one hand, put it into the left (right) inner buccal mucosa of the mouth and wipe it repeatedly for 15-20 times (rotate the genetic sampling cotton swab while wiping).

Take out the genetic sampling cotton swab, put it on the envelope or white paper, and dry it in the shade for more than ten minutes until the saliva is completely dry; (the specific location for wiping is the side of the cheek or the inside of the cheek and cheek – for example, the place where the adult pinches the child’s cheek, from the wipe in the mouth)

4. Collect the second cotton swab (the other side) in the same way, and extract three (six in total) genetic sampling cotton swabs from each side;

5. For gene sampling after drying in the shade, we should put the collection cotton swabs in a marked envelope and seal it (please do not use plastic bags or plastic wrap for the sampling cotton swabs)

6. Take the sample to the laboratory as soon as possible for PCR experiments, or you can choose to mail it to the laboratory or hospital.

How to Obtain an Oral Swab Specimen

If you have been in close contact with symptoms of COVID-19 (15 minutes or more in six minutes), you should get tested.

If you have recently been to someone in an area with a positive case, you should do a swab test;

You are a person who recently travelled or travelled for business, you should take the test;

If you and your family members have recently developed suspicious persons such as fever, dry cough, fatigue, sore throat, and decreased sense of smell (taste) during the self-health monitoring process, you should go for a test;

If you have recently held or participated in large-scale, crowded dinners, parties, conferences, training and other large-scale gatherings of people, you should go to the test.

You can talk to your healthcare provider, your local urgent care, or your state or local health department about where to go to get tested (CDC, 2020A).

What is the most reliable test for COVID-19?

You may have seen the rumour circulating that oral swab tests are not as reliable as nasal swabs. But how is this measured?

Expert research has shown that nasal swabs are easier to detect nucleic acid positive, and the sampling time stays longer in the nasopharynx. Larger doses of samples can be obtained, which is the reason for the higher positive rate of nasopharyngeal swabs reported in the literature.

1. Polymerase chain reaction: fluorescence quantitative PCR, which is suitable for a large number of samples and has a low cost;

2. Second-generation gene sequencing: the NGS method, which is more accurate and can read out which generation of nucleotides and viruses the data came from.

For example, the complete data of the nucleotide sequence of the delta virus is available in the database. We compare the resulting virus to the full data, and if we do, it’s a delta virus. There will be subtle differences in the process of virus transmission, even the first and second generations are different, and subtle differences can be found through comparison. Therefore, it is possible to find out who and where the first-generation patient, patient No. 1, came from during the outbreak of this virus in this local community. It is better to use the NGS method to trace the source of the virus.

Both methods have their own advantages and disadvantages, and both can very accurately reflect whether the nucleic acid test is positive or not, and both can achieve the purpose of detection. If we need traceability. We compare the collected viral nucleotides with viral databases in all databases to aid in diagnosis and guide treatment.

Still, the information on testing for the new coronavirus continues to evolve, to the point where you may feel like you need to become a medical professional or even know where to go first. If you’re wondering whether to get tested and how it works, we’re here to help. Here’s what you need to know about COVID-19 testing and other options.

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.

Flocked Swab Evaluation: Virus Sampling Swab Material and Performance

Flocked 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 affecting the water absorption and hydrophilicity of fluff.

The experiment is to compare the sample collection effects of swabs flocked with different glues.

■ Preparation materials: Flocked swab, control group flocking swab, beaker, dye, water, balance, scale, vernier calliper.

1. The purpose of the experiment

The quality of incoming nasal swabs is guaranteed through the appearance inspection, size inspection and saturated liquid absorption inspection of the anterior nasal swab.

2 Sampling guidelines for flocked swab samples

2.1 Appearance inspection, the quality department conducts sampling according to scientific methods.

The quality personnel shall check whether the swab packaging bag is complete.

2.2 Visual inspection

1. Visually inspect the appearance of the swab to see that there is no lack of glue, no cracks, no deformation, no black spots and heterochromatic spots; (CR)

2. Visual inspection of the head: no damage, false soldering, missing soldering, black spots, looseness, dirt, scorch.

Visual inspection of the material: Compared with the swab sample, whether there is a difference in the material and thickness of the cotton tip of the swab.

2.3 Size check

The inspector carries out dimensional inspection according to the specifications of the material coding system.

2.4 Saturated suction volume

The inspector weighed the flocking cotton swab and recorded it as ml. Transfer it to a qualified preservation solution bottle 15 times. Weigh the swab again and record it as m2 and 0.11g ≤ m2-m1 ≤ 0.18g.

Remarks:

1. Definition of defect level: (MA) is a general defect mark; (MI) is a minor defect mark; (CR) is a serious defect mark.

Nasopharyngeal Swab Sample (Nasal Swab)

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

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

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

How is the COVID-19 nasal swab test performed?

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

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

Nasopharyngeal Swab materials

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

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

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

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

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

Nasopharyngeal swab collection

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

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

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

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

Patients usually get results within a day or two.

Inspection is capable of scanning for many common microorganisms.

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

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

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

How 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. 

  2. How to do a mouth swab COVID-19 test
    3. 

  3. What are the types of COVID-19 tests?
    4. 

  4. What COVID-19 test is more accurate?
    5. 



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.

Virus Test For COVID-19


In this article：

Swab Test;


COVID-19 is an infectious disease,a respiratory disease.


COVID-19 variants_Omicron


The new findings indicate that the new mutation of COVID-19, Omicron, spread earlier than everyone thought, and the scope is wider.


We must do a good job in vaccine injection and virus swab testing is the top priority.

According to the Associated Press, on Tuesday (November 30), the new findings have clearly shown that Omicron has entered many countries before the world has created its own protection system for Omicron.


The Spanish Institute of Public Health Service and Natural Environment (RIVM) detected Omicron in virus samples on November 19 and 23.


According to the World Health Organization, South Africa first reported this type of mutant virus on November 24.


At this stage, it is still not clear where this type of mutation first occurred, nor how infectious it is, but this has not prevented some countries from rushing to implement travel restrictions, especially for tourists from southern Africa.


This measure has been criticized by South Africa, and the WHO has also expressed its resistance, feeling that its actual effect is relatively limited.


The latest developments have also become increasingly clear that the travel ban cannot prevent the spread of new mutations.


The German government stated that they had seen Omicron in a man who had neither been to Africa nor had any knowledge of anyone who had contracted this type of virus.

The World Health Organization reminded on Monday that the risk of Omicron’s worldwide spread is “very high”, and initial direct evidence suggests that it is likely to be more infectious.


The COVID-19 pneumonia epidemic broke out for the first time nearly two years ago, and at this stage, the world’s response at many levels is similar to the disorder two years ago. Including random implementation of travel restrictions, and the lack of grasp of where there are risks and where there are risks.


Senior officials from all over the world try to clear everyone’s fears, saying that their vaccines are still a better way of defense. Be sure to continue to work hard to make vaccination spread all over the world. At the same time, do a virus swab test.


However, regarding the effectiveness of vaccines against Omicron mutations, although the President of the United States is also urging vaccination, the White House President’s medical consultant and the top infectious disease expert in the United States told the ABC TV program on Monday that the experts look forward to one or two in the future. Understand within a week.


What is the maintenance level of the current COVID-19 vaccine against this new mutation? Don’t know yet. But what we can do is to do a good job of virus swab testing and prevention. For example, go out less and party less.

COVID-19 symptoms;


The symptoms of COVID-19 are likely to include dysosmia, high fever, dry cough, dyspnea, chills, headache, muscle pain, sore throat, hematoma, or runny nose. At the same time, it is manifested as conscious fatigue, weakness, and weakness.

This situation may happen 2-14 days after you touch the virus that causes COVID-19.

Not all COVID-19 patients have all of these symptoms, and some people have no symptoms. That is an asymptomatic infection.

Even after recovering from COVID-19, some people are still likely to have unforgettable illnesses, such as fatigue, dry cough, or joint pain. The long-term physical and mental health hazards are unclear, but they may cause permanent damage to the cardiovascular system, lungs, or other human organs. This is more likely to occur in people with more serious illnesses, but it is more likely to occur even in people with milder illnesses.

If you have symptoms, please take a swab. If you have questions or concerns about a medical condition, please consult your health service provider.

For other information, please visit WTO: COVID-19 symptoms.

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.

The DNA extraction flocked swab produced by our company is made by nylon fiber flocked technology. The front end is coated with nylon short fiber fixed vertically. There is no absorption hole in the whole collection swab collection area, and the DNA cells will not disperse and remain in the fibers, which is conducive to faster and more efficient elution.


Independent sterilization packaging.


The benefits of flocked swabs for COVID-19 viral collection.


1. Sample collection process: The unique structure of the front end of the flocking swab can greatly increase the number of samples collected.


2. Sample dissolution process: The brush-like layer structure can release almost all collected samples. There are more advantages for the collection of trace DNA.


3. According to different analysis items, the corresponding soft or brush texture swabs have reached the maximum collection.


4. Disposable sterile sampling swab rod with breaking point.Learn more


5. Flocked swab technology improves the adsorption/release of samples and the sensitivity of the analysis.


6. The front flocked swab sampling is more precise and suitable for extracting more cells from the nasopharynx.


7. Packed in a transparent plastic tube to avoid biological pollution.


In short, the upright nylon fibre is like a soft brush, which can collect more cell samples. The capillary action between nylon fibers enhances the load of aqueous samples, and the samples are concentrated on the surface of the swab, which is easier to elute. Nylon flocking swab can absorb and release more samples.
