How Rapid COVID-19 Antigen Test Kits Work

A rapid COVID-19 antigen test is a test used to detect the SARS-CoV-2 antigens. The SARS-CoV-2 virus causes COVID-19, and it is a highly infectious disease. The way the test works is that the antigens present in the body are made to react with antibodies that are coated in the test kit. When you test positive, an ink dye appears, and when you are negative, nothing happens. 

Rapid COVID-19 antigen tests have been made available to healthcare professionals to help them test for active cases of the virus during emergencies. The rapid tests produce fast results, usually within 15 minutes, to help doctors test more patients at a given time. 

One of the reasons why antigen tests are used is because PCR tests are expensive. Health facilities cannot always rely on PCR tests to continue with normal operations. For PCR tests, samples must be taken to a laboratory before results can be determined. The equipment used with transportation makes the continuous of PCR tests very expensive. That is why many scientists encourage the use of rapid COVID-19 antigen tests.

Why should you opt for a COVID-19 antigen test?

You might be wondering, why is it important to opt for a rapid COVID-19 antigen test? Rapid COVID-19 antigen tests help to detect the SARS-CoV-2 antigens in your body, as the name suggests. When you test positive for a rapid test, it gives you the opportunity to self-isolate yourself which prevents the spread of COVID-19.

How rapid COVID-19 antigen tests work

  1. The first thing to do is collect a sample of the fluid from the nostril or throat using a cotton swab. You do this by inserting the swab into the throat or nose and gently rubbing it to collect the fluid. 
  2. After the swab is removed, you place it into the extraction buffer. You rotate it for about 10 to 15 seconds, then you remove the swab. Whiles removing the swab, you are supposed to squeeze the sides of the tube to collect as much liquid as you possibly can. 
  3. The last thing to do is to add drops of the extracted specimen to the sample collected. You then have to wait for about 15 minutes, then you can read the results. The results become invalid after 30 minutes.

Meaning of the results

A positive antigen test usually displays two colored lines, one in the control region (C) and another in the test region (T). When a colored line appears, it means the SARS-CoV-2 antigens were detected. With a negative result, only one colored line appears, and it appears in the control region. When the results are invalid, no line appears at all. If this happens you have to repeat the test with a new device. This is because there is a possibility the sample was not taken properly. 

Rapid COVID-19 antigen tests only indicate whether the SARS-CoV-2 antigen is present in your system or not. It cannot determine the amounts of antigens in the body compared to PCR tests. With antigen tests, the results must always be used alongside other tests for accuracy and efficiency. Health professionals cannot use only antigen tests to determine if you are truly infected. These diagnostic tests have a low false positive infection probability if the nasal swab is performed by a licensed health care provider. Access to FDA authorized diagnostic pcr, antibody, and antigen test kit devices in many countries these days to help diagnose and identify a person with the infection. PCR tests take longer to obtain results and are more expensive, which make affordable rapid antigen tests the best option.

The best test kit to use

Testing is just one way of combating the virus, disturbing everybody today. To make testing easier, healthcare professionals need to reliable and effective testing kits. With all the regulations put in place, it is now easy to find a variety of testing kits available on the market. 

These diagnostic tests can help stop the public spread. When more of the public is tested, critical decisions and guidance about lock-downs and mandates by the CDC and other organizations can be made. Testing may also provide specific data based on confirmed patient outbreaks to report to the proper government leaders. Health care providers may also want to use tests with high sensitivity and accuracy and specificty to detect antibodies of a suspected asymptomatic person. The tests can help a health care provider triage patients; even those that may be asymptomatic.

Covid-19 test kits approved by the FDA allow individuals to collect samples at home and later send them to a certified lab for analysis to be made. The at-home test results should not be different from on-sight antigen tests.

Rapid COVID-19 antigen tests are used for the qualitative detection of the nucleocapsid protein antigen from SARS-CoV-2 in individuals suspected of coronavirus.  During the acute phase of the infection, positive results indicate the presence of viral antigens.  Positive results obtained from rapid COVID-19 antigen kits are usually highly accurate. The tests can be very specific but not as sensitive as molecular tests.

When the COVID-19 antigen test results are negative, you will need the patient’s history, clinical observations, or epidemiological information to confirm this type of status.  Since negative results are presumptive, so a confirmation test through molecular assay is crucial.  If the patient shows symptoms of COVID-19 but the antigen test shows a negative result, then a molecular test is required.
