How to Swab For Covid Test

Since the outbreak of novel coronavirus pneumonia, we must have experienced nucleic acid testing. Covid swab test Nucleic acid detection plays a very important role in the process of infection diagnosis of COVID-19. It can not only find asymptomatic patients in the incubation period as much as possible but also greatly reduce the risk of infection.

Nucleic acid detection is so important. Next, Dr Li will take you to have an in-depth understanding of the relevant principles of nucleic acid detection, the difference between mixed collection and single collection of nucleic acid detection, and the matters needing attention in nucleic acid detection, to help you better protect yourself while popularizing knowledge.

To understand nucleic acid detection, we must understand the detection principle. Let’s take a look at its detection principle first.

What is the principle of nucleic acid detection?

Nucleic acid, the genetic factor of the virus, is a macromolecular chain composed of four nucleotides. Different molecules represent different nucleotides and form a long chain. Nucleic acid detection is through the detection of nucleic acid in the chain, and this segment of nucleic acid is COVID-19 specific, other viruses do not.

The substance detected by the nucleic acid is the nucleic acid of the virus. At present, the detection technology is mainly through PCR (polymerase chain reaction) technology to detect the nucleic acid of the virus. During the detection, the nucleic acid chain of COVID-19 was used as the detection target, and the target gene sequence was amplified by PCR Test, which was combined with a fluorescent labelled probe added in the test reagent to produce a fluorescence signal.

The three forms of nucleic acid detection have their advantages.

Nasal swab test

This test method is to insert the test swab vertically into the nostril. And gently rotate the swab, stay in the nasal cavity for about 15 seconds, to test.

Compared with throat swabs, nasal swab testing is more accurate for inexperienced testing personnel. And the risk of exposure is lower. However, it is not suitable for some patients with nasal allergies, high blood pressure and people who take anticoagulation and antiplatelet for a long time.

Throat swab test

At present, the most widely used detection method is also a form that is often used by everyone. During the sampling process, the patient opened his mouth and made an “ah” sound, and the testing personnel used a sterilized cotton swab to gently and quickly wipe the pharyngeal lateral wall and posterior pharyngeal wall of the subject many times.

COVID-19 Testing: Throat swab test

Throat swab testing: Often used in the testing process because it is more convenient and fast to collect, and it is more acceptable to the public, but the risk of exposure is also greater.

Anal swab test

This test method is a method of inserting a test swab into the anus and taking a sample at the fold of the anus or taking a sample at 2 to 3 cm for a new coronavirus test.

Many patients reject anal swab testing, but anal swabs can improve the accuracy of testing for new coronavirus infections to a certain extent. Some patients indeed have negative throat swabs, but positive ones are detected by anal swabs. In some patients, the anal swab test was still positive after the other two tests turned negative.

Why do multiple nucleic acid tests need to be performed?

Multiple nucleic acid tests are necessary for epidemic prevention and control.
A negative nucleic acid test does not mean that the tested person is not at risk of infection. Any detection method has the possibility of errors, especially in high-risk areas. To ensure the accuracy of the inspection results and better prevent and control the spread of the epidemic, multiple rounds of inspections must be carried out. There are also the following reasons for taking multiple rounds of detection:

After virus infection, the human body has a certain value-added period. When testing, if the virus in the body does not reach a certain concentration, we may not detect the virus.

When the specimen was collected, due to the different sampling methods, no virus cells were collected. False-negative specimens can also lead to inaccurate collection results.

Errors in the transportation process and storage of samples for inspection will also affect the results of nucleic acid testing.

Therefore, for risk areas and special populations, multiple rounds of nucleic acid testing must be carried out to more accurately and effectively detect the virus source, so as to better and more accurately prevent and control and identify infected people, and cut off the source of the virus. No matter what kind of inspection process, attention must be paid.

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

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

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-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.

    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)

    Maintain a minimum distance of 6 inches from people from other homes.
    When you cannot maintain a 6-inch distance from others, please wear a mask in the room and outdoors.

    If you are vaccinated or not vaccinated, Cell medical strongly recommends that you:

    1. Wash your hands frequently, maintain your hygiene, and open windows every day for ventilation

    2. Try not to go out, if you go out, try to wear a mask

    3. Try not to hold parties and avoid contact if it is not necessary

    4. Pay attention to eating habits, eat more fruits and vegetables, exercise, and keep a good sleep

    5. Cover your nose and mouth when sneezing, and don’t spit anywhere

    If possible, work from home.
    Clean and disinfect the surface.

    Please do a nasopharyngeal swab test and isolation work before going home. For the health of you and your family.

    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.

    Nasal Swab VS Oral Swab

    Some customers inquire:

    Are nucleic acid tests all about poking the throat?

    Will you poke your nose?

    “Poke the nose” through the Internet is more accurate,

    is that true?

    Don’t panic, let’s learn about it with Xiao Liu from Cell medical!

     

    When doing nucleic acid testing,
    There is a very important project,
    Just do a throat swab
    There are two types of throat swabs-nasopharyngeal swab and oropharyngeal swab sampling.

    Currently
    Most hospitals use
    Oropharyngeal flocked swab
    Because-it is the most convenient to collect samples and less painful.

    But there are rumors,
    The detection rate of nasopharyngeal swabs is higher,
    is that true?
    Yes! Yes! Yes!
    Studies have shown that the poison load of nasopharyngeal swabs in patients infected with the new coronavirus is much greater than that of oropharyngeal swabs.

    Focus on:
    Wear a mask when you go out!
    Wear a mask when you go out!
    Wear a mask when you go out!

    The important thing is said three times!

     

    Nucleic acid detection, antibody detection

    confuse?

    After the new coronavirus infects the human body, it will first reproduce in the respiratory system. Therefore, it can be determined whether the human body is infected with the virus by detecting the viral nucleic acid in the sputum and nasopharyngeal swabs.
    To
    After a period of infection, usually 7-10 days, the human body will produce specific antibodies against the virus. IgM antibodies will appear first, and then IgG antibodies will appear. Therefore, detecting these specific antibodies can determine whether the human body has been infected with the virus. ,

    If allowed,

    You can, according to your own tolerance,

    Choose whether to do a nasopharyngeal swab or an oropharyngeal swab.

    in addition,

    The serum antibody test is to draw venous blood,

    No need to fast!

    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.

    About Nylon Flocked Nasal Swab

    Cell medical produces a special flocking swab for coronavirus collection, which has excellent sample collection and release ability, can quickly adsorb micro samples, and has a high release timeliness rate. The increase of the number of targets is helpful to improve the sensitivity of rapid diagnostic test.

    COVID-19 nucleic acid detection is one of the criteria for the diagnosis of cases. It is the key to early detection, early diagnosis, early isolation and early treatment, as well as the basis for isolation treatment of infectious source and medical observation of close contacts.

    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

    Collection of nasopharyngeal swabs.

    What is a flocked swab?

    NYLON FLOCKED SWABS FEATURES:

    *Ergonomics and anatomical design:

    Patient comfort and cell sample collection efficiency improved at the same time.

    nylon flocked nasopharyngeal swab

    nylon flocked nasopharyngeal swab

    *High-quality sample elution:

    Unlike traditional swabs, when the sample does not come out of the mattress core.

    Nylon Flocked Swab has an open fiber structure that can immediately transfer the sample cells to the liquid medium.

    *Rapid absorption (the improved sample collection)

    The static electricity is sprayed on the fibre and fixed evenly and vertically on the top of the coater.

    This powerful capillary effect quickly absorbs cell samples.

    *Increase analysis sensitivity:

    Nylon flocked cotton swab can quickly elute more than 95% of the original sample,

    so it is easy to improve the analytical sensitivity.

    *Just collect, capture and transport:

    Peel off the pouch, collect cell samples,

    and clip the applicator shaft into the provided delivery medium or cuvette tube.

    *Quantitative volume transfer:

    Measurable and consistent absorption and transfer from the patient to the test tube,

    without an internal mattress core,

    disperses and holds precious samples like traditional fiber swabs.

    In contrast, the entire sample remains close to the surface for rapid and complete elution.

    *Vertical nylon fiber:

    Such as a soft brush, can improve the collection of cell samples.

    The capillary interaction between nylon fiber bundles not only facilitates the strong water absorption of cell samples

    but also keeps the cells close to the surface, which is more convenient for elution.

    *Certified without inhibitors and interferences:

    Swabs collected are certified DNase, RNase free, and human DNA free.

    They also do not contain any PCR inhibitors.

    Certificate of analysis for each batch.

    *Ideal for automation:

    Compared with the traditional fiber wound swab, the 4n6 DNA swab only released a small amount of fibre during the extraction process.

    This avoids the risk of clogging the pipettes and probes used by the liquid handling robot.

    1. Sampling is more comfortable and convenient.

    Our company uses the existing technology “spraying technology” to vertically attach millions of nylon flocked micro fibers to the head of medical grade handle through the flocking process of electrostatic charge. The function of vertical nylon fiber is similar to that of soft brush. Using this soft brush in the sampling process makes the user feel no foreign matter. At the same time, the flocking swabs used in different parts adopt different breaking points, and the rod adopts different thickness to make the softness different.

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

    Sterile Flocked Nylon Swab with 80mm Breakpoint.

    2. Flocking swab samples release more.

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

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

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

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