What’s The Difference Between COVID-19 Rapid and PCR Tests?

As New Year’s Day approaches, the number of new crown infections is also rising. Therefore, once you have symptoms of infection. Or you are exposed to the new coronavirus. If you are going to an environment with a high risk of infection.

You must continue to be tested.

Currently two COVID-19 detection methods-polymerase chain reaction (PCR) test (also known as reverse transcription-polymerase chain reaction test) and a rapid antigen test.

So, which detection method should we choose? What is the difference between the two?

On the COVID-19 website, terms such as PCR, rapid test, and antibody test are difficult to understand and which one is correct for you. In this article, our goal is to explain the difference between the two most common tests for diagnosing COVID-19: rapid antigen test and polymerase chain reaction (PCR) test.

Rapid antigen test

Antigen test (often called rapid test). This test detects protein fragments specific to coronavirus. We can do the antigen test in a clinic, doctor’s office or hospital. The turnaround time for results is usually very fast, and in some cases, we can get report results within 15 minutes. There are usually false negatives (the results indicate that the patient does not actually have a coronavirus) or false positives (the results indicate that the patient does not actually have the coronavirus).

If you feel unwell and have undergone a rapid negative test, you may need to undergo a PCR test for further confirmation. However, when someone is at the peak of infection, rapid antigen testing usually provides accurate results because this is when the virus levels in the body are highest.

The rapid antigen test is usually used as a screening tool to detect that you may be infected with the new crown, but PCR monitoring is required to confirm the final result.

Although a negative rapid antigen test result does not necessarily mean that you are not infected, it at least protects your contacts than not testing at all.

PCR TEST

PCR swab tests are similar to rapid tests in several respects because they can be used in symptomatic or asymptomatic patients and can be tested with nasopharyngeal swabs.

The swab test is considered the “gold standard” for SARS-CoV-2 detection. This test actually detects RNA (or genetic material) unique to the virus, and it can detect the virus within a few days of infection, even for those who have no symptoms. This test can be performed in a clinic, hospital or even in your car. The turnaround time is longer, generally in the range of 2-3 days, but the result may be within 24 hours. When the demand is high, the result may take a week or more.

What if the rapid test is negative but there are still symptoms?

The current recommendation is that if you still have symptoms and the rapid test is negative, you should have a confirmation test (PCR test). This is especially true if you have high-risk exposures. High-risk exposure is considered to be contacted with a COVID-19 positive individual for more than 15 minutes within 24 hours, and the distance between you and the individual is no more than 6 feet.

What kind of test should be done? When will it be done?

RT-PCR (reverse transcriptase-polymerase chain reaction) detection if the following situations occur:

1. Symptoms of new crown infection appear.
2. Having contact with people infected with the new crown.
3. The rapid antigen test result is positive, and PCR identification is required.
4. The Ministry of Health requires testing before lifting the quarantine.
5. The Ministry of Health requires that an inspection must be carried out before obtaining permission to travel to a certain area.

If you want a quick antigen test:

1. Have a plan to go to a place with a high risk of infection.

2. Contact with high-risk groups (such as the elderly) and hope to protect them.
3. You have symptoms of COVID-19, but you cannot go to the PCR test site.
4. Activities with a large number of participants in the field, if indoor activities are carried out, the risk of infection is greater.
5. Check whether you have the SARS-CoV-2 virus as soon as possible.
6. Participate in regular COVID monitoring projects.

    Covid Sampling Flocked Swab

    Flocked refers to the process of applying multiple lengths of fibers to the surface of the adhesive coating.

    It is basically the same as the cotton swab except for the material.

    It can also be said that the flocking adheres to the head of the flocked swab. It is a flocking swab, but it is different from cotton swabs in that it is a disposable sampling swab composed of nylon short fiber fluff head + ABS plastic rod.

    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.

    The cell medical company flocking swab is made of nylon fiber flocking technology. The front end of the flocking swab rod is coated with nylon short fiber fixed vertically so that there is no absorption hole in the whole collection swab collection area. Learn more

    The sample will not disperse and remain in the fiber, which is conducive to faster and more efficient elution.

    To limit the damage to the sample and improve the accuracy of detection, the cotton swab is made of completely inert parts.

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

    what are flocked swabs used for?

    Flocked swabs are specimen collection devices that are ideal for use in diagnostic testing.

    They are capable of efficiently collecting organisms and cells at the collection site and have the ability to rapidly release cells.

    If the swab head is flocking, it is a flocking swab.

    1. Sample collection and transportation.

    The outbreak of the new crown epidemic, no matter where we are. We may have been exposed to nucleic acid testing, and most of the sampling swabs used by medical staff are flocked materials.

    The nasopharyngeal sampling swab is composed of a nylon short fiber fluff head and medical-grade ABS plastic rod. The role of nylon short fiber is like a soft brush, which can effectively improve the collection of cell material; the capillary movement between the fibers forms a strong hydraulic pressure, thereby taking in the liquid sample; at the same time, the sample is close to the surface of the swab and is easy to wash.

    What Makes Flocked Swabs Different than Traditional Swabs?

    We all know cotton swabs, but we may not know flocking sampling swabs.
    XiaoLee will discuss with you what flocking swabs are and what are the advantages of flocking swabs over cotton swabs.

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

    Traditional cotton swabs cannot 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.

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

    The detection of viral nucleic acid sequence based on reverse transcription-polymerase chain reaction (RT-PCR) technology is the main method for large-scale screening of new coronary pneumonia. Normally, nucleic acid detection technology has the characteristics of early diagnosis, high sensitivity and specificity, but Sample collection and storage, personnel operation, nucleic acid extraction, kit performance, etc. are all causes of false-negative or false-positive test results.

    Flocking 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 that affects the water absorption and hydrophilicity of villi.

    Are flocked swabs used for flu testing?

    Of course！

    Influenza is very common in winter and spring. The clinical manifestations are mainly high fever, fatigue, headache, cough, and systemic muscle pain and other symptoms of systemic poisoning, with mild respiratory symptoms.

      As we learn more about COVID-19,

      Protect yourself and others: COVID-19, do a new crown swap test and get a new crown vaccine.

      On this page, you will learn:
      What should we pay attention to during holiday gatherings?

      Of course, Cell Medical recommends minimizing unnecessary gatherings. For you and your family and friends.

      The latest mutation of the new crown epidemic has increased the risk of transmission.

      Faced with the epidemic, but the company arranges to travel, what should I do?

      Please do a nasopharyngeal swab test before going home.

      About nylon flocked nasal swab

      What should we pay attention to during holiday party activities?

      Cell medical company offers a variety of ways to enjoy the holiday tradition and protect your health.

      We encourage colleagues in the United States to take the following steps to make your holiday gatherings safer.

      To do a nasopharyngeal swab test, maybe we have to confirm whether we have been to a high-risk area before the party. Whether to carry the new crown virus, a flocking nasopharyngeal swab test is the best choice.

      Take a COVID-19 swab test so you can find out before you go. You can go to the test site or use the home test program. Of course, we recommend that you go to a professional testing agency for nasopharyngeal swab testing.

      Some locations may be closed on or around holidays. Check it a few hours before departure.

      vaccination. The best way to ensure the safety of your family and friends is to get vaccinated if you and your family are eligible.

      If you feel unwell, please stay at home. If you have symptoms of COVID-19 or a positive swab test, please stay at home and away from others. And notify the government personnel of the first pass to conduct another virus test, and do not attend the party.

      Of course, nowadays, you must wear a mask before going out. This is for the health of you and your family and friends.

      You need to wear a mask when taking public transportation, including buses and airplanes.

      Of course, party us

      Gather in an outdoor or well-ventilated place.

      According to experience, the most likely way of transmission of the virus is through saliva or droplets. Therefore, during the epidemic period, try to avoid contact with others and face-to-face conversations.

      During the party, we should pay attention to eating clean cooked food and boiling water.

      Ask the party host to try not to choose to eat some wild, uncommon, and strange food.

      At the same time, the weather is volatile, and your handsome colleagues pay attention to adding or removing clothing.

      Finally, Cell Medical recommends minimizing unnecessary gatherings.

       

      The latest mutation of the new crown epidemic has increased the risk of transmission.

      Infectivity may increase by 500%! Powerful mutant strains broke out in various countries in the world!

      On the 27th local time, several countries and regions, including the United Kingdom, Germany, Italy, and Israel, discovered the new variant “Omicron” (Omicron) of the new crown.

      At this stage, countries around the world have tightened their epidemic prevention measures at different levels.

      The Israeli government announced that it will gradually prohibit all foreigners from entering the country on the evening of the 28th local time. Resolutely putting an end to the spread of the “new coronavirus mutant strain Omi Keron” has become a new starting point for epidemic prevention worldwide.

      Authoritative American experts think: “The infectivity of the new mutant strain may increase by 500%.”

      On November 27, WHO announced that the new mutant strain discovered in South Africa was named Omicron.

      On the 26th local time, the Federation of American Scientists emphasized that in comparison with the Delta mutation, the total number of “bad thorn gene mutations” in the new mutation was twice that of Delta.

       

      “The B.1.1.529 variant is likely to have a strong charisma of 500%, which is by far the most surprising statistic.”

      On the 26th local time, the United States announced that it will gradually restrict the citizens of South Africa and seven other non-US African states to travel to the United States from the 29th.

      Previously, the United Kingdom, the European Union, and many other places have called for the suspension of flights originating from African countries.
      The new mutant new coronavirus “Omi Keron” first discovered in South Africa has spread rapidly

      According to foreign media reports, in Gauteng Province, where the population of South Africa is more concentrated, 90% of the recent increase in virus cases is related to this strain. The Israeli Ministry of Health issued a statement on the 26th stating that the first case of “Omi Keron” virus infection was found. The case came from Malawi, Africa, my country. The Belgian Minister of Environmental Health, Van den Brock, confirmed that the host country has found the infection case of the mutant strain “Omi Keron”. According to reports, this is also the first diagnosed case in Europe.
      The first case of Omi Kiron strain infection occurred in Italy…

      The spread of new mutant strains is astonishing, which has aroused great vigilance in all countries!!!

      Facing the epidemic, but the company arranges to travel, what should I do?

      Of course, the best option is to refuse a business trip. But often this is not something we can decide.

      Everyone is based on the following suggestions to alleviate the spread of COVID-19 to protect themselves and others.

      The more processes you use to mitigate the spread of COVID-19, the safer you will be. When it comes to avoiding the spread of COVID-19, no step is perfect.

      1. Reduce your risk of COVID-19

      2. Actions and natural environment maps with lower risk and higher risk.

      3. Proposals for participants and theme event planners: COVID-19

      Vaccination. The COVID-19 vaccine is one of the appropriate ways to avoid being infected or spreading COVID-19.
      If you are not vaccinated (including children)

      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.

      Covid Swabbing

      Speaking of a Covid sampling Swab. We believe everyone will not be unfamiliar at this time. Because the detection tool used at this time is a possible sample.

      Sample swabs directly contact our human organs, such as nasal swabs and throat swabs for testing. Therefore, the selection of the material of the sampling head is very important, and the material of the sampling head is related to the detection of the test.

      Flocked swab Sample with the large amount and release amount, a large number of materials contain substances that are difficult to affect dye detection.

      Omi Keron strain Covid Swabbing

      The team of Professor Huang of Nankai University discovered this through big data modeling and analysis.

      The infectivity of Omi Keron is about 37.5% higher than the infectivity of the new crown mutant strain Delta.

      The Netherlands and Brazil both reported cases of infection with the Omi Keron strain of the new crown virus on the 28th.

      To reduce the spread of the Omi Keron strain, all the people in Bots have recently appeared in the agency. The movement has a new crown for passengers in Bonawana, Malawi, Lesotho, Swaziland, Namibia, Mozambique, and Zimbabwe. Virus detection.

      On the 28th in Hubei Province, two cases of Miokeron strain occurred in the capital of Ottawa, Canada.

      Following reports of Omi Keron infections in some countries including a week later, this strain was infected with a mutant strain that “needs attention” on the 26th.

      The United Kingdom, Germany, Italy, Russia, and Australia successively reported cases of infection with this strain on the 2nd and 28th. Ireland, New Zealand, Australia, the United Kingdom, Canada, the Netherlands, and the Czech Republic have also reported relevant cases.

      For the spread of the virus strain, many countries have prepared measures and taken protective measures.

      How to obtain a nasopharyngeal swab specimen?

      Overview.

      Nasopharyngeal swab specimen collection of respiratory mucosal surface specimens is a method for the diagnosis of Covid-19 novel coronavirus in adults and children.

      This operation can also detect patients with suspected respiratory infections caused by other viruses and bacteria.

      There are no special contraindications for nasopharyngeal swab specimens. However, clinicians should treat the following conditions with caution: the recent history of nasal trauma or surgery, severe nasal septum deviation, chronic nasal obstruction, and severe coagulation.

      Preparation for nasopharyngeal swab specimen sampling.

      The nasopharyngeal swab is a special sampling tool, which consists of a sampling head made of soft plastic or flocked nylon. In addition to nasopharyngeal swabs, operators also need personal protective equipment (PPE) such as isolation gowns, non-sterile gloves, protective masks, and face shields.

      Before starting to use, please make sure that all virus sampling tubes are labeled, and the analysis application form is filled incorrectly.

      Nasal Swab Sampling Steps

      We recommended that patients with suspected Covid-19 type coronavirus infection wear masks.

      The patient took off the mask and blew his nose with a paper towel to remove excessive secretions from the nasal passages.

      Take out the tissue. Slightly lift the patient’s head so that it can wipe into the nasal passage. Ask the patient to close his eyes to alleviate the slight discomfort caused by the operation.

      Along the nasal septum, gently push the swab above the bottom of the nasal passage forward until you feel a sense of resistance indicating that the swab has reached the nasopharynx.
      Insert the swab in the nostril parallel to the upper jaw.

      If resistance is encountered during pushing the flocked swab, the scraper should be withdrawn, try to adjust the angle and then push again, at the same time closer to the bottom of the nasal passage.

      The depth of the nose insertion should be equal to the distance from the nostril to the opening of the external auditory meatus. CDC recommends keeping the sampling head for a few seconds after it reaches the nasopharynx, allowing the sampling head to absorb the secretions, and then slowly rotating the swab to discharge it slowly (people who have done nasopharyngeal swabs will appreciate which kind of sourness Cool feeling). Your institution may also recommend sampling for a few weeks after exiting the spin. Ask the patient to wear a mask.

      Nasopharyngeal swab specimen processing.

      Open the sampling tube with virus transport medium, put in the flocking swab, fold out the sample tube in the groove, and discard the tail. Tighten the label sampling tube cover, and wipe the sampling tube with a sterile wipe.

      Then place the sampling tube in the biohazard bag opened by the assistant. Some departments may require you to put the samples back in their original packaging and then send them for inspection. According to CDC guidelines, process the swab sample directly, or put the sample in a preservation solution or store it at room temperature.

      How to Choose a Correct Virus transport medium for COVID-19 Testing

      Disposable virus sampling tube

      Disposable virus sampling tube

      At present, 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 sample, the result is invalid regardless of the subsequent treatment.

      Selecting appropriate virus transport media and collecting flocking swabs can improve the efficiency of new crown detection.

      Almost all virus preservation solutions on the market contain non inactivated viruses directly, resulting in high infection risk for sampling, transportation and testing personnel.

      Therefore, the front line of epidemic prevention needs to be able to inactivate virus samples directly.

      At 37 ° C, we compared the preservation effects of cell medical (Dongguan) preservation solution containing guanidine hydrochloride and guanidine isothiocyanate with that without guanidine salt on avian coronavirus.

      After 1-7 days of storage, under the same condition of 37 ℃, the preservation rate of virus nucleic acid was basically maintained at 100% when it was preserved with cell medical (Dongguan) preservation solution;

      ·Use virus preservation solution that can protect the sample from high temperature inactivation.

      The results showed that high temperature inactivation had no significant effect on the integrity of coronavirus nucleic acid when coronavirus nucleic acid samples were preserved with high temperature inactivator.

      The virus preservation solution developed by Cell medical (Dongguan) company is divided into inactivated and non inactivated. Different preservation solutions can be selected according to different test requirements and test conditions. If you have any questions or needs, please call us. Choosing cell medical (Dongguan) virus transport media solution in China is your right choice.

      Furan compounds (guanidine isothiocyanate or guanidine hydrochloride, etc.) are typical protein denaturants.

      They are often used to extract cell lysis in nucleic acid and inactivate virus. However, the furamethoxam component does not have the ability to work at room temperature.

      Because the ability to preserve viral nucleic acid is easy to lead to sample degradation, it is not suitable for preserving new coronavirus samples. Therefore, it is strongly recommended that you choose the preservation solution without guanidine salt.

      To this end, we call on the majority of medical personnel to select non inactivated virus transport media if they take samples for the purpose of nucleic acid detection and do not need to culture live viruses.

      Vtm Swab | Virus Transport Medium with Sampling Swab

      Use a virus medium that inactivates the virus.

      At present, covid-19 detection is mainly to detect viral RNA, which needs to divide the virus.

      Therefore, as long as the integrity and stability of virus nucleic acid can be guaranteed, there is no need to preserve live virus.

      Therefore, in the current situation of fighting COVID-19, it is ideal to inactivate the virus while collecting samples. Some manufacturers have also introduced inactivated transport medium, but its inactivating component is guanidine salt.

      The results showed that the salt forming component storage solution had insufficient storage capacity for viral nucleic acid at room temperature, which was easy to cause sample degradation.

      Therefore, we recommend the use of virus preservation solution containing non guanidine protein denaturants.

      The volume of solution in the sampling tube should be appropriate.

      ① When sampling each sample separately, we recommend that you select a virus sampling tube containing 1ml storage solution to ensure the correct storage capacity. It can not only meet the downstream needs of nucleic acid extraction and detection. Compare with 3ml storage solution. Triple the virus concentration!

      ② For large-scale preliminary screening and mixing test, we should choose to put the samples of 3-5 people into the sampling tube.

      ·Use a virus preservation solution that can transport and preserve samples at room temperature.

      If the delivery temperature does not meet the standard, the viral nucleic acid may degrade, resulting in a “false negative” test result!

      On the contrary, if cell medical uses a virus storage solution that can transport and stably store virus nucleic acid at room temperature.

      We solved the problem of sample transportation and improved the accuracy of test results.

      ·Use virus preservation solution that can protect the sample from high temperature inactivation.

      However, the research reports of Beijing Center for Disease Control and prevention in the Journal of “clinical chemistry” and Beijing Preventive Medicine Research Center show that high temperature inactivation can lead to the degradation of virus nucleic acid, thus reducing the detection rate of virus nucleic acid. Therefore, The false negative rate of New Coronavirus nucleic acid detection is high.
