What You Need to Know About Rapid Covid-19 Antigen Tests

Most countries that have been affected by the Coronavirus Disease 2019 (COVID-19) are implementing the testing strategy proposed by the World Health Organization (WHO). Scaling up this strategy means mass testing and increased use of polymerase chain reaction or PCR tests, which is costly and time -consuming.

Rapid COVID-19 antigen tests are game-changers when it comes to boosting the testing capacity which in turn strengthens the fight against the coronavirus in most low- and middle-income countries. Antigen-based rapid diagnostic tests have revolutionized the response to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Therefore, countries with weak health systems need better testing strategies.

As much as the gold standard molecular tests are the most accurate and efficient in diagnosing individuals for the COVID-19 virus, this technique requires high-tech laboratories, multiple reagents, and highly qualified experts to run the process. For this reason, there was a huge need for a less involving option that can speed up testing.

Rapid COVID-19 antigen tests are affordable, take less time to display results (15–30 minutes), and they can be used in point-of-care settings. Individuals no longer have to wait for 24 hours to up to ten days for their coronavirus testing results to be produced. For once, healthcare providers can now achieve their testing goals and easily identify the nature of the spread of Coronavirus in a target population.

According to the rapid antigen test developers, these devices detect antigens, or proteins, found on the surface of the SARS-CoV-2 virus. Rapid COVID-19 antigen test kits are more accurate when they are used on patients that develop COVID-19 symptoms, especially those that have a high viral load.

The WHO recommends test kits that show an accuracy performance rate of more than 80%.  Since their sensitivity and specificity rates do not match that of PCR tests, they can be considered as complementary approaches to molecular testing.

These inexpensive test devices ais to detect antigens, protein structures on the surface of SARS-CoV-2.  These tools are not designed to replace PCR tests. Rapid COVID-19 antigen tests can be applied where there is no access to PCR testing, in areas with widespread community transmission, in remote or hard-to-reach areas, and used in tracking the extent of the outbreak.

Different from the rapid antibody test kit, the antigen-based kit makes use of bodily fluids taken from a nasal swab. The specimen is applied on a paper strip, similar to that of a pregnancy test, and a buffer solution is added.  The dye in the solution changes color to display a positive or negative result.

The portable nature of the rapid COVID-19 antigen tests makes them ideal for use in close-contact settings and areas that comprise high-risk groups of people such as health workers. The design of these kinds of testing devices is intended for patients with high levels of antigens, so individuals in the early stage of the SARS-CoV-2 infection are likely to test negative.

Increased access to testing helps a lot in determining the spread of the coronavirus disease, but the accuracy of the results does rely on the quality of the rapid COVID-19 antigen test kit used.  These tests are designed purposely for medical professionals and health care providers trained to administer diagnostic tests. The antigen-based POC tests need no additional equipment, so you do not need scientific expertise to use them.

Rapid COVID-19 antigen tests have become popular in screening travelers at the borders, employees in workplaces, foreign workers, and guests at community events. Some of the close-contact settings that are ideal for antigen-based testing include:

  • Wedding receptions
  • Live performances
  • Sporting events

Generally, rapid COVID-19 antigen tests are ideal for remote areas that lack the appropriate laboratory facilities or trained health providers to carry out molecular tests such as the PCR tests. Antigen-based tests are easy to use and require less training.  They come just in time to help remove testing backlogs and hiccups as most nations plan to ease restrictions and open up their economies.

When rapid COVID-19 antigen tests are used in populations that have a very low prevalence, false positive and negative results are more likely to occur. In such settings, a confirmation test is usually done using a PCR test, the gold standard for diagnostic testing. Authorities in Singapore are testing migrant workers using antigen tests once every week and every two weeks using polymerase chain reaction (PCR) tests.

As much as nations are testing for the COVID-19 virus, a preventive approach should be encouraged. Ordinary people should continue to keep a social distance, wear masks, and wash their hands. 

If you are looking to purchase rapid COVID-19 antigen tests from a trusted supplier online, then Rapid Connect Medical is your best bet. The company allows you to make orders of up to 10,000,000 or more FDA EUA approved COVID-19 antigen test kits. The higher the number of kits in your order, the lower the price per item.

Rapid COVID-19 antigen tests are designed for use in point-of-care or patient care settings such as emergency rooms, schools, or the doctor’s office. The FDA has authorized the use of this Point of Care (POC) antigen test in patients suspected of having contacted SARS-CoV-2. According to FDA and antigen test manufacturers, these special kits are ideal for use within five days to one week of symptom onset.

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.
