All About Repid Antigen Test | Covid-19 Testing
As part of its effort to respond to the COVID-19 pandemic, FDA plays an important role in helping to support the development of accurate and reliable tests in the U.S.
There are two main categories of tests inthe fight against COVID-19:
Diagnostic tests and antibody tests. Diagnostic tests can tell you if you currently have an infection. The FDA has authorized many diagnostic tests for COVID-19, including molecular tests. Molecular tests work by looking for the virus' genetic material in a sample from you. This sample is then usually analyzed in a lab. For some tests, the sample can be analyzed at the point-of-care, such as at a doctor’s office.
FDA-authorized molecular tests are very accurate,and results are returned anywhere from minutes, to several days, depending on the test. Antigen tests are another type of diagnostic test that see if there are viral proteins in a sample taken from inside your nose witha swab. These tests are often simpler and may provide results quicker than many molecular tests, sometimes within minutes in a doctor’s office.
Although antigen tests can be less accurate and may need confirmation with an additional diagnostic test, they can be made more widely available because they’re easy and simple. The other category of test is an antibody test, sometimes called a serology test. Antibodies are produced by your body whenyou’re infected by a virus and help your immune system fight off the infection. An antibody test detects antibodies to the virus using a blood sample. If an antibody test finds antibodies in the blood, it likely means the person has been previously infected with the virus. Antibody tests do not show if you have a current infection and should not be used to diagnose a current infection from COVID-19.
The results from antibody tests can help us better understand questions about exposure to COVID-19 by helping identify: who has been infected and has developed antibodies; if antibodies may provide protection from future infection; who may still be at risk; or who may be eligible to donate a part of their blood called convalescent plasma, which may serve as a possible treatment for those who are seriously ill from COVID-19. If you have questions about COVID-19 diagnostic or antibody tests, talk to your doctor.
