Your doctor may suggest getting antibody tests for these diseases to determine whether you are up to date on vaccinations and need boosters or to diagnose an autoimmune disease like lupus. These diseases include measles, mumps, hepatitis, mononucleosis, and varicella-zoster virus. Other antibody testsĪntibody tests can also be used to look for antibodies of other diseases, reports the NIH. The FDA adds that a negative result could mean it’s possible you had a previous SARS-CoV-2 infection, but your body did not make antibodies yet, or that the level of antibodies made by your body is too low to be measured by the test. Negative results from a COVID antibody test indicate that antibodies to COVID were not detected in your blood. Positive results from a COVID antibody test indicate that you had a previous SARS-CoV-2 infection or COVID-19, reports the FDA. What will the COVID-19 antibody test results tell me? An antibody test cannot tell you if you currently have COVID-19, says the CDC. However, the antibody test can tell you only if you have had a previous infection. PCR and antigen tests can tell you whether you are currently infected with COVID-19, notes the CDC. What is the difference between these tests and antibody tests? Solv features a directory that can help you find nearby COVID testing. These rapid tests return results within a few minutes, and can be performed by a healthcare worker or yourself at home, reports the CDC. AntigenĪn antigen test works by finding SARS-CoV-2 molecules on the virus surface, reports the Massachusetts Institute of Technology. Results from these lab tests usually come back within several days, says the CDC. The CDC notes that a PCR test can detect COVID in its earliest stages. Most viruses, including COVID-19, contain DNA or RNA, adds the NIH. PCRĪ PCR test works by finding the DNA or RNA of a pathogen or abnormal cells in a sample, reports the National Institutes of Health (NIH). Your sample is then analyzed using a polymerase chain reaction (PCR) test or antigen test. In addition, the CDC reports that a viral test can determine whether you are currently infected with SARS-CoV-2.ĭuring the viral test, a healthcare worker will take a sample from either your nose or mouth. What tests are used to diagnose COVID-19?ĬOVID-19 can be diagnosed using a viral test. However, the CDC says this test should not be used in place of viral COVID testing to determine if you have a current infection or if you have immunity to SARS-CoV-2 after getting the COVID vaccine. The main reason antibody testing is done, according to the CDC, is to determine whether you have COVID-19 antibodies in your blood and have had a past infection. It adds that this test can also help you understand population-level protection. If you do, you have either been infected with COVID-19 or have recovered from it, adds the FDA.Īccording to the CDC, the COVID antibody test can help you determine how well your immune system defends itself against the virus. This antibody test can tell whether you have SARS-CoV-2 antibodies in your blood. SARS-CoV-2 is the virus that causes COVID-19. Your body develops antibodies in response to infections like COVID-19 or after receiving vaccinations.ĪCCORDING TO THE FDA, the COVID-19 antibody test is formally known as the SARS-CoV-2 antibody test. When is antibody testing done, and why is it important?Īn antibody test, also known as a serology test, can detect antibodies in your blood.
