![]() ![]() However, they use a slightly different technology to detect that genetic material which allows it to run in point-of-care (CLIA waived) settings at room temperature.ĬUE tests are an example of rapid molecular test that can be conducted from a nasal swab sample from a patient. Rapid Molecular Test - Rapid molecular tests are similar to PCR tests in that they detect the genetic material of the virus SARS-CoV-2 in order to determine if you have COVID-19. Examples include BinaxNOW, QuickVue, iHealth, and FlowFlex. These include point-of-care, laboratory-based, and self-tests. There are several antigen tests currently authorized by the FDA. Antigen tests are typically performed on nasopharyngeal or nasal swab specimens. Rapid Antigen Test - Antigen tests are designed to detect the presence of a specific particle on the outside of the virus, known as the ‘antigen.’ Presence of the antigen implies active viral infection. Scientists use the PCR technology on the sample they collect from you to make copies of specific genes present in SARS-CoV-2 in order to detect if you have COVID-19. PCR Test - Polymerase Chain Reaction (PCR) test for COVID-19 is a molecular test that looks for the genetic material of SARS-CoV-2, the virus that causes COVID-19, from a sample collected from your upper airways. Samples for diagnostic tests are typically collected with a nasal or throat swab, or saliva collected by spitting into a tube. Molecular and antigen tests are types of diagnostic tests that can detect if you have an active COVID-19 infection. If you develop symptoms, get a test and stay home. Individuals who have had close contact with someone with COVID-19 need to follow the most up-to-date quarantine guidance below, regardless of a negative test result or in the event they cannot access a test. Tests are a snapshot in time, and one negative test after exposure does not mean you will not test positive later. The recommendation to test after exposure is to allow individuals who test positive to isolate quickly and prevent additional spread. Individuals who have been exposed to someone with COVID-19:
