Information About Rapid Covid-19 Antigen Tests

Rapid COVID-19 Antigen Test

Covid-19 is a virus that can easily spread from person to person. This illness was first detected in December 2019 in Wuhan, China, and started spreading rampantly. Today, the virus has spread to over 200 countries, infecting millions of people around the globe, with the U.S having the highest infection rate. The World Health Organization characterized this as a global pandemic in March 2020.

Health professionals are trying to find ways and means to fight this virus. One way to fight the virus is by testing. Testing helps to identify infected patients who are immediately isolated from the general population to prevent further spread. There are various types of testing namely Polymerase Chain Reaction (PCR) testing, antibody testing and antigen testing.

You cannot identify active cases without testing people, and you have to know the type of test you are taking. This is to help you know what your results mean and shows you the steps you need to take to protect yourself and others around you.

What is an antigen?

Simply put, an antigen is a toxin or foreign substance that is capable of stimulating or inducing an immune response. Each antigen has features which are recognized by the immune system. Relating antigens to Covid-19 is not as complicated as it sounds. SARS-CoV-2, the virus responsible for Covid-19 has several known antigens. 

There are two main types of antigens recognized by the body, autoantigens and foreign antigens. Autoantigens originate within the body, while foreign antigens originate from outside the body. Foreign antigens are usually produced by virus or microorganisms and can be dangerous when it finds itself in the body. 

The body usually recognized autoantigens and foreign antigens and reacts accordingly. When the immune system recognizes an antigen that is dangerous for the body, it produces antibodies that help fight the antigens.

What are antigen tests?

An antigen test is a test that detects and reveals whether a person is currently infected with the SARS-CoV-2 virus. The antigen test is not effective if the person is not infected because the antigen of the virus disappears. Antigen tests detect proteins such as spike proteins which are usually found on the surface of the SARS-CoV-2 virus.

Antigen tests take a longer time to develop because the suitable antibodies needed to make the test effective must be known. But once this is done, bulk production of the test is bigger and better than other tests. One problem with antigen tests is the accuracy in results. Antigen tests have lower sensitivity as compare to PCR test which makes it difficult to produce accurate results, usually producing false-negative results.

Aside from that, antigen test makes testing of patients easier and faster. The administration of antigen tests is not restricted to only health personnel, because the procedure is simple as compare to other tests. Antigen tests produce results within minutes which can make bulk testing easier and faster. Production of antigen tests are also cheaper than PCR tests. 

Is testing necessary?

Testing is very necessary, especially if we want to go back to our normal lives. There is a need to find every infected person, and make sure they have recovered. Scientists are trying to create a vaccine that will protect people from the virus, but before the vaccines are commercialized, testing is needed. 

Identifying and isolating infected patients protects the general healthy population. Without testing, it will be difficult to know who has been infected and who needs treatment. You can help make testing easier by going to a testing center to check your status. Testing positive should not make you panic, because treatment of the virus is now easier than previously.

The best testing kit to use

Testing is just one way of combating the virus affecting 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. 

According to the FDA, the rapid COVID-19 antigen test is categorized as an in vitro diagnostic test, and it should only be used under the Emergency Use Authorization (EUA).  Most of these testing kits are only available by prescription.  Under the EUA, these tests and critical medical devices can be accessed during an emergency or when there are no adequate, approved, and available testing options.

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.

You need to be proficient in performing COVID-19 tests in point of care settings for you to use a POC rapid antigen test.  We are talking about medical professionals, clinical laboratory personnel, and trained operators.  Individuals who think that they have coronavirus disease 2019 (COVID-19) and need to get a test to verify are advised to contact their health care providers as soon as possible.
