COVID-19Common questionAre antibody tests used to diagnose COVID-19?No. An antibody test does not detect the presence of the SARS-CoV-2 virus to diagnose COVID-19.These tests can return a negative test result even in infected patients (for example, if antibodies have not yet developed in response to the virus) or may generate false positive results (for example, if antibodies to another coronavirus type are detected), so they should not be used to evaluate if you are currently infected or contagious (ability to infect other people).May 19, 2021

Can COVID-19 antibody tests be used to evaluate immunity to COVID-19?
COVID-19Common questionCan COVID-19 antibody tests be used to evaluate immunity to COVID-19?The FDA issued a safety communication to remind health care providers and the public that results from currently authorized SARS-CoV-2 antibody tests should not be used to evaluate a person’s level of immunity or protection from COVID-19 at any time, and especially after the person received a COVID-19 vaccination.May 21, 2021
Likewise, What does the detection of Covid -19 antibodies in my body mean?
COVID-19Common questionWhat does the detection of Covid -19 antibodies in my body mean?When antibodies are found (a positive test result), it may mean that a person was infected with SARS-CoV-2 and their body’s immune system responded to the virus at some point in the past. People develop antibodies when their body’s immune system responds to an infection. These antibodies can be found in the blood of people previously infected whether or not they had signs or symptoms of illness.Feb 12, 2021
What is the difference between a COVID-19 swab test and an antibody blood test?
COVID-19Common questionWhat is the difference between a COVID-19 swab test and an antibody blood test?A swab or spit test can tell only if you have the virus in your body at that moment. But a blood test shows whether you’ve ever been infected with the virus, even if you didn’t have symptoms.Feb 3, 2021
Can someone test negative and later test positive on a viral test for COVID-19?
COVID-19Common questionCan someone test negative and later test positive on a viral test for COVID-19?Yes, it is possible. You may test negative if the sample was collected early in your infection and test positive later during this illness. You could also be exposed to COVID-19 after the test and get infected then. Even if you test negative, you still should take steps to protect yourself and others. See Testing for Current Infection for more information.

COVID-19Common questionWhat does it mean if I test positive for COVID-19 antibodies if I never had symptoms?You may test positive for antibodies even if you have never had symptoms of COVID-19.

COVID-19Common questionWhat is the best time to get tested for COVID-19 for the most accurate results?Evidence suggests that testing tends to be less accurate within three days of exposure, and the best time to get tested is five to seven days after you were exposed.
