The COVID-19 Antibody Test is used to determine if your blood has antibodies to the SARS-CoV-2 virus, the virus that causes COVID-19. Antibodies may be found in the blood when the body is responding to or has responded to an infection, such as COVID-19. Antibodies may give full or partial immunity to the virus.
Antibodies to the virus that causes COVID-19 may be present as early as seven days after the onset of symptoms. Unfortunately, it may take as long as fourteen days after the onset of symptoms for antibodies to develop. To ensure more accurate test results, we recommend that you be tested for antibodies at least fourteen days after the onset of your symptoms.
Antibody testing is not used to diagnose current COVID-19 infection. For information about COVID-19 Active Virus Testing, please click here.
POSITIVE TEST RESULT
NEGATIVE TEST RESULT
EQUIVOCAL TEST RESULT (NEITHER POSITIVE NOR NEGATIVE)
A positive, negative, or equivocal antibody test result does not have any relationship to contagiousness. You could have a positive, negative or equivocal antibody result and still be shedding virus and spreading the disease to others. Therefore, we cannot write a note for you to return to work certifying that you are not contagious based on your antibody result. We can only report the actual result.
