RATs are based on the principle of antigen-antibody interaction. Since the COVID-19 pandemic, awareness of RATs is no longer limited to health professionals and COVID-19 has become the expected referent, so more precise usage is required in other circumstances. Rapid antigen tests for the detection of SARS-CoV-2, the virus that causes COVID-19, have been commonly used during the COVID-19 pandemic.įor many years, an early and major class of RATs-the rapid strep tests for streptococci-were so often the referent when RATs or RADTs were mentioned that the two latter terms were often loosely treated as synonymous with those. Rapid tests generally give a result in 5 to 30 minutes, require minimal training or infrastructure, and have significant cost advantages. Such tests are a type of lateral flow test that detect antigens, distinguishing them from other medical tests that detect antibodies ( antibody tests) or nucleic acid ( nucleic acid tests), of either laboratory or point-of-care types.

In the safety and privacy of one of our consulting rooms, we can provide you with a fast and reliable rapid antigen test in the UK. If you need a lateral flow or rapid antigen test for travel in Northampton, contact West Chemist. This is good news because you can get these results very quickly, sometimes in as little as 15 minutes. However, many travel destinations and organizations now regularly accept a negative lateral flow or rapid antigen test. With a PCR test, you can trust both a positive and negative result. A certain amount of the virus needs to be present to trigger a positive result in a rapid antigen test so if you receive a negative result, you may still have covid-19. If you receive a positive lateral flow test result, you can trust that it’s correct.
This doesn’t mean lateral flow tests aren’t accurate. Because this test is more precise, it can detect lower levels of the virus and in some cases, it can detect a past covid-19 infection. To test for the presence of the virus, the sample is sent to a lab for analysis. PCR tests are a more precise way to test for the presence of covid-19. While lateral flow tests and rapid antigen tests are the same, they are different from covid-19 PCR tests. PCR Tests vs Lateral Flow/Rapid Antigen Tests So if you’ve been told you need a lateral flow or rapid antigen test and you’re worried you’re going to book the wrong type of test, you can rest easy. To do this, the test looks for proteins or antigens that are present in a person’s body when they are infected with covid-19. While they sound like they’re different, both of these terms actually refer to the exact same test.Ī rapid antigen test uses lateral-flow technology to test for covid-19. You’ve probably heard the terms ‘lateral flow test’ and ‘rapid antigen’ a lot over the past two years.
