Nasopharyngeal Swab Pcr Test

Nasopharyngeal Swab Pcr Test

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.

COVID-19 Saliva Collection Kit

How accurate are saliva swab DNA tests?

Is the DNA test of the saliva swab accurate?

Many people doubt the accuracy of the saliva swab test.

However, you can rest assured, because the accuracy of oral saliva swab testing is as accurate as other DNA testing methods.

Moreover, this is not the same as a finger puncture or a blood test, it is not painful at all.

In recent years, DNA testing has become more and more popular.

Whether you want to confirm your parental relationship, understand where your genes come from or want to optimize your exercise.

We are currently working on direct-to-consumer DNA testing of saliva swabs.

You have decided to use DNA testing to better understand your body and optimize your training.

However, before you take the first step and buy a set of home DNA testing kits, you should have some concerns.

Although most of the feedback and research has been confirmed to be positive, we are here to learn more about this and help you make an informed decision.

How much saliva is needed for a DNA test?

Saliva Sample Collection Kit :Disposable saliva DNA RNA sampling tube

Saliva Sample Collection Kit: Disposable saliva DNA RNA sampling tube

2ml-4ml.

The saliva collection components are easy to use, and each set has detailed instructions.

You can provide samples for different health conditions, including common medications used during pregnancy, colds or flu (including medications for acid reflux or heartburn).

But if you want to use drugs to reduce the white blood cell count, such as chemotherapy, you’d better wait two weeks or wait until the white blood cell count returns to normal.

After mixing with DNA stabilizing buffer, the temperature range of your saliva sample (-4oF to 122oF) is stable.

Please send the collected samples to the laboratory as soon as possible.

Is the DNA test at home accurate?

Yes, DNA testing at home is very accurate.

You will only encounter errors when the genetic sample is damaged (for example, you have eaten before the sample is collected) or the laboratory quality is poor.

Therefore, it is necessary to choose a well-known DNA testing supplier for testing.

An accurate genetic test report can know in advance whether the body is in danger of disease.

By improving the living environment and behaviour habits, avoiding or delaying the occurrence of the disease, or determining whether there is a specific drug in the case of malignant disease.

Target, so as to more accurately select the treatment method.

The results in each report are derived from at least three peer-reviewed research papers.

It just repeats the genes that have an impact on health, health and nutrition.

This means that you can change the way of real-life based on the genetic variants you carry.

Through strict internal and external procedures, we have passed ISO27001 certification to identify risks, evaluate all control systems, improve our reliability and security, and comply with international data security standards, so as to ensure that our customers and business partners can trust us.

What can you do to ensure that your DNA test results are accurate?

In order to ensure that your DNA test results are accurate, you need to follow the instructions at the back of the box.

Before starting, please read the instructions carefully:

Before wiping dry, make sure you have nothing to eat or drink.

-The best time to take the exam is to brush your teeth in the morning and the first thing before drinking the first cup of tea.
Before taking the test, it is best to open the sealed mouth swab to ensure that it will not be affected.

After removing the cotton swab, open your mouth and use a pointed tip (cotton swab, slightly larger) to gently wipe your cheeks.

Try not to scrub vigorously, because the important part of the sample is saliva.

Be sure not to put paper towels in the plastic container provided.

Take care to break the pole where it is needed.

Fill out the attachments, sign and seal the enclosed envelope, and then send it to the laboratory for inspection.

Bear with patience and watch your test. This process will start with the receipt of samples in the laboratory and will take 10-14 days.

Is the accuracy of mouth swab detection relative to other DNA collection methods?

Because the saliva swab is noninvasive, many people question its accuracy.

However, you can rest assured that the accuracy of oral swab detection is as accurate as other DNA detection methods. And, unlike finger punctures or blood tests, it doesn’t hurt at all.

Whether you are building a cabinet in IKEA, pressing a map or doing DNA testing, you can get accurate results as long as you follow the instructions.

Remember, DNA testing is wrong only if your test results are wrong or you don’t follow the instructions.

Cost is an important factor in performing such tests, so it must be studied.

Often, you don’t just pay for the test suite. You also have to pay a test fee to analyze your results. If the test you selected does not belong to the laboratory, please choose a supplier with a good reputation and excellent laboratory.

Every laboratory we use will conduct regular spot checks to ensure that your samples have been tested correctly and your results are 100%.

How does a Covid Mouth Swab Test work?

How does a Covid Mouth Swab Test work?

How does a Covid Mouth Swab Test work?

I went for a swab test for the new coronavirus the day before yesterday, and the result came out yesterday and it was negative. Some friends asked me, is the throat swab test painful? How to do it? What are the types of COVID-19 tests? What COVID-19 test is more accurate? Today, Dr Lee came to give everyone a popular science.

You can use a variety of tests to determine whether you have COVID-19. Some tests are collected by mouth swabs, and some are collected by nasal swabs or saliva. In the experiment, an oral flocked swab was used to collect samples from the oral cavity for oral inspection. This is different from a saliva test, which spits out saliva into a small container.

On this page, you will learn:

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

What is a mouth swab? Painful?

The COVID-19 test is the most important way to diagnose the new coronavirus. Nucleic acid is the genetic material RNA of the new coronavirus. The nucleic acid test is to check a certain segment of RNA. If it is positive, it means that you are infected with the new coronavirus.
According to different sampling sites, nucleic acid detection can be divided into many types, such as throat swabs, anal swabs, tracheal secretions, alveolar lavage fluid, and so on.
Among them, throat swabs are the most commonly used, and oropharyngeal or nasopharyngeal secretions are taken for laboratory tests.

Oropharyngeal swab, the inspection process is very fast, no more than 10 seconds, only needs to open the mouth, and the staff uses a cotton swab to take a sample in the oropharynx.

Covid Mouth Swab Test work

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.

COVID-19 Swab Test : Positive Covid Test

COVID-19 Swab Test : Positive Covid Test

Despite the recent surge in coronavirus cases, most Premier League clubs hope to continue playing during the holiday season. Due to the Covid-19 outbreak, only half of the game last weekend was left, and each round of new swab tests will continue to yield results of increasing cases.
This led several top coaches to question the safety of continuing.
Currently, all fans can still enter the stadium. However, there are reports that the UK may adopt secondary measures after Christmas. According to these regulations, only 2,000 spectators are allowed to watch the game.

Here is how to test for COVID-19 and what to do if the test result is positive.
 Stock up on healthy foods and anti-fever medicines, and avoid contact with others. Try to watch football matches at home.

COVID-19 testing methods.

COVID-19 infections have surged again, so you may find that you test positive.
With the highly contagious variant of Omicron circulating in many countries, reinfection is common, and people who are vaccinated may be susceptible to mild infections.
It is important to take precautions and be prepared to act if you are infected.

Here is how to do it:

How to confirm if you have COVID-19

As we all know, the symptoms of Covid-19 include “fever, fatigue, and dry cough”. Some patients will have symptoms such as nasal congestion and runny nose. Viruses are also a very large family. In the face of a turbulent epidemic, how doctors can quickly distinguish whether it is a “2019-nCoV” virus infection in the first place is obviously the key to fighting the epidemic.

What are the symptoms of COVID-19?

Some people infected with the virus have no symptoms. When the virus does cause symptoms, common symptoms include fever, body aches, dry cough, fatigue, chills, headache, sore throat, loss of appetite and loss of smell. In some people, COVID-19 can cause more serious symptoms, such as high fever, severe cough, and shortness of breath, which usually indicates pneumonia.
People with COVID-19 can also experience neurological symptoms, gastrointestinal (GI) symptoms, or both. These may or may not have respiratory symptoms.
For example, COVID-19 affects the brain function of some people. Specific neurological symptoms seen in people with COVID-19 include loss of smell, tastelessness, muscle weakness, tingling or numbness in the hands and feet, dizziness, confusion, delirium, seizures, and stroke.
In addition, some people have gastrointestinal (GI) symptoms such as loss of appetite, nausea, vomiting, diarrhea, abdominal pain, or discomfort related to COVID-19.
If you have been (or you suspect you may have been) exposed to COVID-19, You should also test whether you are experiencing symptoms.

How to test for COVID-19?

Special diagnostic tests must be performed to confirm that someone has an active coronavirus infection.

In most cases, the clinician will take a nasopharyngeal swab (or nose and throat swab).

Certain tests can be performed with saliva samples. Then check the genetic material of the virus in the sample (PCR test) or specific viral protein (antigen test).

Antibody testing can tell if someone has COVID-19. But an infected person does not immediately start to produce antibodies. It can take up to three weeks for a blood antibody test to become positive. This is why it is not useful as a diagnostic test for people with new symptoms.

How reliable is the test against COVID-19?

COVID-19 Swab Test: flocked swab test kits

COVID-19 Swab Test: flocked swab test kits

Currently, there are two types of diagnostic tests in the United States. The PCR test can detect viral RNA. Antigen tests (also called rapid diagnostic tests) detect specific proteins on the surface of the coronavirus. Antigen test results may recover within 15 to 45 minutes; you may need to wait a few days or longer to get PCR test results.

The accuracy of any diagnostic test depends on many factors, including whether the sample is collected correctly. For PCR tests that are usually analyzed in the laboratory, the test results may be affected by the conditions under which the test is shipped to the laboratory.

The test time will also affect the results. For example, if the test is performed on the day of infection, it is almost certain that the test result will be negative because there are not enough virus particles to detect in the nose or saliva. If the test is performed a few days after infection or a few days after the onset of symptoms, the chance of getting a false negative test result will decrease.

Generally speaking, if the test result is positive, it is almost certain that the person has been infected.

The negative test result is uncertain. The false negative rate of antigen testing is higher. If your antigen test result is negative, your doctor may order a PCR test to confirm the result.

Self-quarantine for 10 days

If you test positive for the virus, you should self-quarantine for 10 days.

CDC says this means don’t leave your home unless there is an emergency.
How soon after contracting the new coronavirus will I start the infection?
Emerging research shows that people are actually most likely to spread the virus to others within 48 hours of the onset of symptoms.

If you live with your family or roommates, keeping your distance is a challenge.
The ultimate goal is that you do not share the air with anyone else.

This means sleeping in a separate room with a separate bathroom, rather than in the same space, such as a kitchen or living room.

Ideally, have friends or family members leave food and drinks outside the door for you to collect.

What does self-quarantine or quarantine mean? What should I or shouldn’t I do?

It is important not to spread the infection to other people during the recovery process.

Although home isolation or home isolation sounds like a stay, you should be prepared for a long time during which you may feel disconnected from others and feel anxious about your own health and the health of your loved ones.

Staying in touch with others over the phone or online can help maintain social relationships, ask for help, and update others based on your situation.

Separate yourself from other people and animals in the house.

Stay in a specific room as much as possible and stay away from other people in your home. Use a separate bathroom (if available).
Wear a mask when you are sick.

Wear a mask when you are with others or pets, and before entering a doctor’s office or hospital.

Cover up coughing and sneezing.

When coughing or sneezing, cover your mouth and nose with a tissue, and then throw the used tissue into the lined trash can.

After sneezing, immediately wash your hands with soap and water for at least 20 seconds. If soap and water are not available, use an alcohol-based hand sanitizer with an alcohol content of at least 60% for cleaning.

Clean your hands often.

Wash your hands often with soap and water for at least 20 seconds, especially after blowing your nose, coughing or sneezing; going to the bathroom; before eating or preparing food.

If soap and water are not readily available, use an alcohol-based hand sanitizer with an alcohol content of at least 60% to cover all surfaces of your hands and rub them together until it feels dry.

Avoid touching your eyes, nose and mouth with unwashed hands.

Don’t share personal household items

Do not share dishes, drinking glasses, cups, eating utensils, towels or bedding with others or pets at home.

Monitor symptoms

Check your temperature twice a day to monitor if you have a fever and stay alert for coughing or breathing difficulties.

If you are asymptomatic and start to have a fever or fever, cough or difficulty breathing, immediately limit contact with others (if you have not already done so).

Call your doctor or local health department to determine if you need a medical evaluation.

What are UTM Swab, Swab Kits?

On November 9, 2021, South Africa detected a B.1.1.529 variant of the new coronavirus from a case sample for the first time. In just 2 weeks, the mutant strain became the absolute dominant mutant strain of the new crown infection cases in Gauteng Province, South Africa, and its growth was rapid.

The form of New Coronavirus is still very serious.

As the first step of covid-19 detection, the importance of sample collection and preservation is beyond doubt.

The influencing factor is sample collection; If there is a problem with the collected samples, the results will be invalid regardless of the subsequent processing.

Selecting appropriate virus transport media and collecting flocked swab can improve the detection efficiency of new crowns.

Quick questions and answers about COVID-19 UTM Swab testing?

COVID-19 is a new variant of the very common viral family known as coronavirus, which can lead to respiratory tract infections, from the common cold to more serious diseases, such as severe acute respiratory syndrome (SARS). Although coronavirus is most commonly found in animal-like cattle, cats, and bats, in some cases, coronavirus can be transmitted and transmitted among humans, such as COVID-19 and SARS, of which nearly 8000 people were sick when they broke out in 2003.

According to the information currently shared by the new crown virus database GISAID, the number of mutation sites of the new crown virus Omi Keron mutant strain is significantly more than that of all the new crown virus mutant strains that have been circulating in the past two years, especially in the virus spike (Spike) protein mutations. . It is speculated that there may be three reasons for its emergence:

(1) After being infected with the new coronavirus, patients with immunodeficiency have undergone a long period of evolution in the body to accumulate a large number of mutations, which are transmitted by chance;

(2) a certain animal group infection New coronavirus, the virus undergoes adaptive evolution during the spread of animal populations, with a higher mutation rate than humans, and then spills into humans;

(3) This mutant strain has continued to circulate for a long time in countries or regions where the mutation monitoring of the new coronavirus genome is lagging. , Due to insufficient monitoring capabilities, the intermediate generation viruses of its evolution could not be detected in time.

The genome analysis of the Omi Keron mutant strain showed that its mutation site does not affect the sensitivity and specificity of mainstream nucleic acid detection reagents in my country.

The mutation sites of the Omi Keron mutant strain are mainly concentrated in the highly variable region of the S protein gene.

The nucleic acid detection reagent primers and probe-target regions were published in the eighth edition of the "New Coronavirus Pneumonia Prevention and Control Program" (China CDC Virus The ORF1ab gene and N gene released by the disease to the world).

However, data from multiple laboratories in South Africa suggests that nucleic acid detection reagents that detect the S gene may not be able to effectively detect the S gene of the Omi Keron variant.

Yes,’ if you’re going to a public place, it’s recommended to wear a mask. As long as the nose and mouth are covered, a scarf, handkerchief, or homemade non-medical mask can play a protective role.

It’s really important to wash your hands before and after putting on a mask.

About COVID-19 Swab Test

About COVID-19 Swab Test

About COVID-19 Swab Test

The new crown virus has mutated continuously.

From Delta to Omi Keron, the COVID-19 virus has continued to mutate, and the global epidemic is prevalent at a high level.

Canada announced that all entry personnel from all countries except the United States are required to be tested for the new coronavirus.

At this time, whether you are leaving the country or entering the country.

I even worry or doubt whether I have contracted the coronary disease.

Perhaps understanding the new coronavirus test has become a compulsory course for most people.

What is the new crown swab test, how to collect a nasopharyngeal swab?  Is nasal swab sampling painful?  If your test result is positive, what do we need to do?  Why do most virus tests choose to flock swabs? Is nasopharyngeal swab accurate? Should you be tested for nasopharyngeal swab samples?

We talked with Dr. Li of Cell medical to learn more.

What is the COVID-19 test and what are the test methods?

Nucleic acid detection (RT-PCR Test) method, antibody detection, and antigen detection.

A swab test simple, effective, and fast way to detect COVID-19.

Including nasopharyngeal swab testing and oropharyngeal swab testing.

Medical staff will use flocked swabs to take samples from the nose and throat and put them into the virus sampling tube.

There are two types of swab sample testing: molecular test (PCR) and antigen test.

How to perform a COVID-19 nasal swab test?

The COVID-19 nasal swab test involves inserting a 6-inch flock (a long stick with a very soft brush) into the cavity between your nose and mouth (nasopharynx).

The medical staff inserts the flocking swab into each nostril for about 15 seconds and rotates it several times to collect enough samples for testing.

The samples are then sent to the laboratory for testing, and our test results are usually known within or within the next day

Since the nasopharynx is in a sensitive position of the body, it will produce a lot of very strange sensations.

On the one hand, the swab is inserted deeply into your nose and it irritates the lacrimal glands.

At this point, you don’t know if you are moved to tears or you are crying in pain.

The nasal swab test is not very painful, but it is very uncomfortable. Some people may have nausea during the nasopharyngeal swab test. Nasal swab painful.

Because the swab will also touch the back of your throat, this reaction is normal.

Whether it is tearing or nausea, nasal swab testing is a common phenomenon.

Don’t worry, everything is normal.

Are there other types of COVID-19 swab test methods available?

Yes, an oropharyngeal swab is one of the options.

Of course, if you want to experience another feeling, an anal swab test is also a good choice.

But they are not as sensitive as the COVID-19 nasal swab test.

Israel’s development of the new coronavirus saliva detection method” saliva detection still needs scientists to confirm on a larger scale. There is no conclusion yet, but it is promising.

In addition to nucleic acid testing for the detection of viral genetic material, there is also antigen testing.

Currently, nasal swab testing for COVID-19, including nucleic acid testing, is still the best choice.

How about the covid test kit at home? Are their results reliable?

The home covid test kit sounds very attractive.

Home covid test usually refers to individuals collecting samples of themselves or their family members through sampling swabs.

We put the collected samples in test tubes with a virus transport medium, and then transport them to the testing facility.

Although you can use the Home covid test kit to test COVID-19 safely and comfortably in your own home.

However, Dr. Li suggested that it should be carried out at a professional testing institution.

Because the quality of the samples we collect and the integrity of the samples during transportation will affect the sampling results.

How accurate is the nasal swab test for COVID-19?

How to obtain a precise nasopharyngeal swab specimen?

Polymerase chain reaction (PCR) uses a piece of DNA as a template.

Then, with the participation of DNA polymerase and nucleotide substrate, the DNA is amplified to a sufficient amount for structural and functional analysis.

Pcr nasal swab test can be said to be very sensitive.

Scientists use PCR technology to amplify a small amount of RNA in the sample into deoxyribonucleic acid (DNA) and replicate it until COVID-19 (if present) is detected.

The following may affect the accuracy of PCR nasal swab sampling.

1. Smoking, drinking or chewing gum 30 minutes before use may also interfere with the test results.

2. Touching the swab with the hand or other objects and using the tip of the cotton swab will affect the accuracy of the detection.

Of course, the professionalism of the most important sampling personnel, we have to choose a professional testing agency for testing. And professional VTM Kits.

What should I do if the new coronary pneumonia nasal swab test is positive?

Very bad news!

If the COVID-19 nucleic acid test is positive, a single room isolation treatment should be carried out immediately.

Consultation by in-hospital experts or attending physicians will conduct multiple tests.

Under the premise of ensuring safety, the patient is safely transferred to a designated hospital for diagnosis and treatment.

Don’t worry. You need to actively cooperate with treatment

Otherwise, life is likely to be in danger, and large-scale infections will also occur.

In addition, proper physical exercise should be carried out in life to enhance the individual’s immunity. Colds and fatigue should be avoided.

Don’t do strenuous exercise, so as not to aggravate the disease.

A friend around me was infected with COVID-19. But my nasopharyngeal swab was negative. Is there any way to confirm that I have had it or am I immune to it now?

Certainly.

Antibody test, also called serological test, can detect the antiviral protein IgM and IgG antibodies produced by your immune system in the blood.

What are the types of samples for serum antibody testing?

It is generally blood, including serum, plasma, and whole blood.

Nasal Swab Pcr Test

To do a good job of normalization prevention and control, we should accelerate the improvement of detection capacity and carry out nucleic acid and antibody detection on a large scale.

This is not only conducive to accurate prevention and control, maintaining people’s health, but also conducive to the rational flow of personnel and promoting the full resumption of work and production.

Nasopharyngeal swabs are used for nasopharyngeal sampling of respiratory diseases such as COVID-19, influenza, avian influenza and hand foot mouth disease.

For nasopharyngeal Swab Pcr Test, Pay Attention to the Following Points:

1. Please do not take antibiotics a few days before rhinitis swab Pcr Test.

2. Do not rinse your mouth with disinfectant or smear the lesion a few hours before making a nasopharyngeal swab.

3. Don’t eat, smoke or drink a few hours before making a nasopharyngeal swab.

4. If the patient’s turbinate is hypertrophic and the nasal tract is narrow, and the insertion resistance of nasopharyngeal swab is relatively large, we can’t use force rashly. We can try to use the other nasal cavity, or directly use oropharyngeal swab to collect.

5. After sampling, gloves shall be replaced, hands shall be disinfected, and disinfectant shall be sprayed on the place where the patient has touched.

In special times, you should also remember to wear a mask and do a good job in personal hygiene. Once you find a virus, please isolate it to avoid re infection.

Nasal Swab Virus Sampling Kits.

Nasal swabs PCR test process

At present, most virus nucleic acid detection kits use fluorescence quantitative PCR to determine whether the sample contains virus nucleic acid by detecting the accumulation of fluorescence signal. So, what steps do nucleic acid detection need to go through? To sum up, there are five steps: sampling, sample retention, preservation, nucleic acid extraction and computer detection.

sampling

Collect human secretions. Wipe the nasal cavity or posterior pharyngeal wall and bilateral tonsils with nasopharyngeal swab or pharyngeal swab

Sample retention

Immerse the swab head into the cell preservation solution, and tighten the tube cover immediately after breaking the tail

preservation

Put the sample tube into a sealed bag, keep it and send it for inspection in time

nucleic acid extraction

Send the sample to the laboratory for nucleic acid extraction

On machine detection

The extract was amplified by fluorescent PCR
