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.

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 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

Posted on by

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 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.

    COVID-19’s large-scale community screening is the main means to cope with the recent outbreak of small-scale epidemics at home and abroad.

    At present, New Coronavirus’s mixed sample nucleic acid detection has become a routine method to effectively enhance the screening and detection of nucleic acid in community population.

    The pooled sample test of covid-19 increase the sampling rate and meet the growing needs of low-risk populations.

    What is a Pooled Sample Test?

    “mixed detection”, that is, nucleic acid test of Pooled Sample.

    On the one hand,it is a method to sample several people, such as 3 or 5 or even 10, and then put them into the same virus sampling tube.

    On the other hand,pooled Sample means combining the same type of specimen from several people and conducting one NAAT laboratory test on the combined pool of specimens to detect SARS-CoV-2.

    What is the significance of nucleic acid test in Pooled Sample?

    COVID-19 Pooled Sample Testing Advantages

    Because a virus sampling tube only puts one person’s sample, the cost will be very high, and the detection time is long, which is not suitable for large-scale nucleic acid detection.

    In principle, the single sample sampling mode is only applicable to high-risk areas and key populations.

    In order to improve sampling efficiency, shorten sampling time and reduce sampling cost. Multi Country selection of Pooled sample test scheme.

    For example, when 5-in-1 mixed sampling test is used, the result is negative, which means that all five people are negative.

    On the contrary, once positive or weak positive is found, it will be traced immediately.

    Re collect single tube swabs for review, and then determine which of the 5 people is positive.

    Therefore, the cost of 5-in-1 mixed mining is relatively low.

    This also caused the 5-in-1 mixed sampling mode to be five times faster than the previous mode of using a virus sampling tube for a human sample.

    One of the biggest disadvantages of sample merging is the decrease of associated test sensitivity.

    Analyzing multiple samples in a single reaction effectively improves the flux, but it also dilutes a single sample and may reduce the weak positive signal from outside the detection limit.

    In short, pooled sample testing is mainly used for large-scale screening to check asymptomatic coronavirus infected persons. It is suitable for large-scale testing projects such as schools, factories, units and urban areas. It has the advantages of efficient screening and resource saving.

    Although reduced detection sensitivity is acceptable for screening services in asymptomatic populations.

    However, When providing diagnosis for high-risk or symptomatic patients, we must give priority to the accuracy of the results.

    The special preservation tube for Pooled Sample test uses medical grade PP as raw material, unique structural design and manufacturing process to prevent liquid leakage. And has the characteristics of high temperature resistance, high pressure resistance and high-speed centrifugation resistance.

    Nasal swab for flu_Rapid antigen (nasal or throat swab) test

    Influenza is common in winter and spring. The clinical manifestations are mainly systemic poisoning symptoms such as high fever, fatigue, headache, cough and systemic muscle pain, while the respiratory symptoms are mild.

    Influenza viruses are prone to mutation, infectious, susceptible to population and high incidence rate. They have caused many outbreaks in the world, and are important public health issues worldwide.

    Why should we detect and prevent influenza?

    According to the World Health Organization (WHO), seasonal influenza can cause 3-5 million severe cases and 290000-650000 deaths worldwide every year.

    The researchers believe that children under the age of 5 are at high risk of severe influenza, but children under the age of 2 are at the highest risk, and infants under 6 months have the highest hospitalization rate and mortality.

    Pregnant women, infants, the elderly, patients with chronic basic diseases and other high-risk groups have a higher risk of serious diseases and death after suffering from influenza.

    Nasal swab for flu : common influenza test method

    Nasopharyngeal sample collection

    Nasopharyngeal sample collection

    Influenza is an acute inflammation of the respiratory tract caused by the patient’s infection with influenza virus. The patient can have a series of symptoms such as cough, expectoration, fever, sore throat, stuffy nose, runny nose and general fatigue. In case of influenza, we should conduct relevant examinations in time to further clarify the diagnosis, including the following tests:

    First, blood routine test, patients with influenza can promote the increase of lymphocytes. If combined with bacterial infection, there can be the increase of leukocytes and so on.

    Second, scientists can culture throat swabs of influenza viruses. In throat swab culture, researchers can detect the related virus.

    Third, influenza patients can do second-generation sequencing, including sputum second-generation sequencing, which can determine the type of virus infected.

    Fourth, influenza patients can do the detection of respiratory pathogens to further clarify the pathogens of infection.

    At present, the two most common influenza tests are rapid antigen diagnostic test  and influenza virus cell culture test. Both tests rely on Nasopharyngeal swabs, pharyngeal swabs, etc. for virus sampling. The most commonly used sampling swab is nylon flocking swab.

    Nasal swab for flu:Application

    It is suitable for the detection and sampling of COVID-19, influenza virus , hand foot mouth disease virus, COVID-19, measles rubella and other types of viruses.

    About nasal swab sampling

    Why use flocked nylon swabs?

    flocked swabs_Cell medical (Dongguan) Co., Ltd.

    flocked swabs_Cell medical (Dongguan) Co., Ltd.

    Flocked nylon swab: excellent sample collection / release ability, release rate > 90%.

    Conventional fiber swab: the sample is intercepted by the gap in the fiber mass. That is, the sample is penetrated, diluted and intercepted in the fiber.  Acquisition is slow and release is slower.

    The sampling time of flocked swab is 3-5 seconds, while that of traditional swab is 15-120 seconds or even longer.

    This caused pressure on the staff during the diagnosis process. Only by extracting samples faster can we complete the collection and analysis more efficiently.

    Precautions for patients with nasopharyngeal swab:

    ① Please do not take antibiotics a few days before making nasal swabs;

    ② Do not use disinfectant mouthwash or smear the focus a few hours before nasal swab.

    ③ Do not eat, smoke or drink a few hours before doing nose swab.

    Precautions for Sampler:

    ① . the sampler shall stand on the side of the patient for sampling.

    ② The patient is required to pull down the mask to expose only his nostrils. In case of sneezing reflex, the patient can cover it with elbows or paper towels.

    If the sampler is not directly in front of the patient, the exposure risk will be lower.

    ③ If the patient’s turbinate is hypertrophic, the nasal tract is narrow, and the insertion of the nasal swab feels resistance. Try to change one side of the nasal cavity or directly change to oropharyngeal swab collection.

    ④ Those with nasal allergy symptoms are easy to induce sneezing. It is recommended to take oropharyngeal swab samples.

    ⑤ Remember to wear a protective mask / screen. For individuals who are highly suspected or basically diagnosed, or who have severe cough and hiccup, they should put on protective clothing.

    ⑥ After sampling, replace gloves, disinfect hands, and spray disinfectant where patients have touched.

    Finally, we should pay attention to nasal swab for flu in special times. Remember to wear masks and personal hygiene when going out. Once you find the virus, please isolate it to avoid re transmission.

    Nasal swab pcr test COVID-19 Antigen Rapid Test Kit

    Detection of COVID-19 by nasal swab PCR is an accurate and reliable method. Positive detection means you may have SARS-CoV-2. Negative detection means you may not have SARS-CoV-2 when testing.

    In order to ensure your safety, if you have symptoms of COVID-19. Or people who have been exposed to the virus and tested positive should be tested.

    What is the symptom of COVID-19?

    If you have the following symptoms,if you have the following symptoms, please buy covid-19 antigen rapid test kit immediately or go to a nearby hospital for PCR test.

    1.Fever;

    2.General fatigue;

    3.cough;

    4.Dyspnea or even respiratory failure；

    5.Nausea;

    6.vomiting;

    7.abdominal pain;

    8.diarrhea;

    Symptoms of New Coronavirus pneumonia are not necessarily typical, and some patients may not have clinical manifestations at the early stage of New Coronavirus infection. Then clinical manifestations will appear, that is, “asymptomatic infection” in incubation period.

    In other words, try to avoid activities in places with crowd gathering, closed space and poor ventilation.

    What is nasal swab PCR test？

    Polymerase chain reaction (PCR) uses a piece of DNA as a template. Then, with the participation of DNA polymerase and nucleotide substrate, the DNA was amplified to a sufficient number for structural and functional analysis.

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

    What should we pay attention to before doing nucleic acid test？

    1.Try not to eat 2 hours before sampling to avoid vomiting.

    2. Do not smoke, drink, drink water or chew gum 30 minutes before sampling.

    3. The tester needs to wear a mask correctly and remove the mask before testing;

    4. Wear it immediately after testing, and prepare a spare mask for easy replacement at any time after pollution.

    5.When you feel sour and itchy in your nose or sneeze, you can immediately cover it with a paper towel or elbow.

    Before collecting nasopharyngeal swabs and before being tested, the collection personnel shall be informed whether they have relevant past medical history. For example, history of nasal surgery, history of deviation of nasal septum, blood diseases, throat diseases, etc

    How long will we know the pcr test results？

    The test results of sampling in the morning are generally available from 18:00 to 19:00.

    The detection results of afternoon sampling can generally be queried around 22:00.

    What’s the difference between the PCR and antigen tests for COVID-19?

    Polymerase chain reaction (PCR): PCR is the most reliable and accurate method to detect active infection. PCR tests usually give results in a few hours.

    Antigen detection: detect protein fragments on the surface of covid-19. Antigen detection usually takes only 15 to 30 minutes.

    How can we prevent COVID-19?

    Firstly, keep good personal hygiene habits, wear masks when going out, wash hands frequently, clean the room, and wipe the floor and other furniture with disinfectant. Second, disinfect your hands with 75% alcohol every time you go out and go home, reduce the number of times you go out, and wear qualified masks. And the diet should also be light, do a good job of physical exercise and enhance personal physique.

    Most importantly, if our conditions permit, we should vaccinate and conduct multiple nucleic acid tests.

    If our Nasal swab pcr test results are positive,what should we do?

    If our test results are positive, don’t be afraid. We should wear masks and go to the nearby Hospital for follow-up in time.

    Repeat the nucleic acid test.Don’t be afraid and hide the test results. Timely medical treatment is the best choice.
