Do Rapid COVID-19 Antigen Test Kits Work?

COVID-19 is an infectious respiratory infection caused by the SARS-CoV-2 virus. Since the outbreak of this disease in 2020, the World Health Organization has declared it a global pandemic. The main source of the virus is those who are infected and possibly asymptomatic people. 

Asymptomatic people are infected people who don’t show any signs or symptoms when they are infected with the virus. Some of the symptoms you might experience when you are infected include dry cough, fatigue, fever, loss of breath, sore throat, and other symptoms similar to the common cold. 

There are three types of testing used for the detection of COVID-19 today, PCR tests, antigen tests, and antibody tests. Antibody tests are used to check if you were once infected by COVID-19, and whether your body produced antibodies to fight off the disease. PCR tests are molecular tests used to find the proteins of the virus. PCR tests are so sensitive in detecting the virus, and it has become the preferred form of testing in the U.S. Antigen tests are rapid tests used to detect antigens of the virus.

What is an antigen test?

The rapid COVID-19 antigen test known as rapid tests is a fast test that detects SARS-CoV-2 antigens in the body. For this to work, a nasopharyngeal (nose) swab is used to collect samples of fluid from your nostrils for the test. Antigen tests are used for diagnostic purposes, meaning they are used on people who are suspected to have active cases of the virus. They are known as rapid tests because of how fast results are produced, usually within 15 minutes.

A positive rapid test result means that the SARS-CoV-2 antigens have been detected. Since the coronavirus is similar to other viruses that have been discovered in the past, it might also mean that those viruses were detected. 

A negative test means that no antigen was detected, but this does not mean you are safe, especially if you are experiencing symptoms. You cannot rely on only rapid COVID-19 antigen tests if you want to test for COVID-19. In the situation where you are experiencing symptoms, a PCR test is used to confirm the test results.

Antigen tests are less sensitive than PCR tests, even though they are both used for diagnostic purposes. Because of its low sensitivity it sometimes produces false-negative results, meaning you might be infected, but it is not sensitive enough to detect it. This is why it is usually used to detect active cases of the virus because a positive result means that the virus is definitely present.

How do rapid antigen tests work?

Rapid COVID-19 antigen test kits are like pregnancy test kits, which makes them cheaper and easier during mass production. COVID-19 antigens are mostly located in the nostril or throat. A nasopharyngeal swab is used to collect fluid samples which are used for the testing. The swab with the fluid is applied to a SARS-CoV-2 antibody to check if it reacts. When it reacts with the antibody and antigens are detected, a colored line appears on the test kit. When no antigen is detected, no colored line appears. 

When an antigen test sample is collected, it is important to use it as soon as possible. If it cannot be done immediately, the sample is supposed to be stored in a dry, tightly sealed plastic tube to prevent contamination. Because there are many tests in the market today, it is difficult to know which COVID-19 test you are supposed to opt for. It is advisable to consult your doctor or a qualified health professional to assist and guide you on the right test for you.

The best testing kit to use

Testing is just one way of combating the virus disturbing everybody today. To make testing easier, healthcare professionals need 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.
