What Is A Coronavirus Antibody Test?
Unlike the COVID-19 test which detects the presence of Coronavirus, the Antibody test, also known as SARS-Cov-2 AB test, checks for the presence of antibodies to coronavirus in the patient’s blood. Antibodies are special protein molecules produced by the immune system approximately 10 days after onset of the infection and remain positive long after the infection. This is why the antibody test can be used to detect a past infection with coronavirus.
Who Can Get the COVID-19 Antibody Test?
AllCare implements antibody test only to patients not showing any signs or symptoms of active infection. In case you still have a mild cough or runny nose, we have to wait 7 days after you recover completely and are ready for the test. For the above-mentioned reasons, all patients will need to consult with an AllCare doctor via telemedicine or in-person before they can be considered for COVID-19 antibody tests. Note, that if you are already in our office for completely different reasons, we can offer you to get an on-the-spot test.
Where Is the Covid19 Antibody Test Done?
AllCare offers the blood test to asymptomatic patients at Atlanta, GA. Our doctor must make sure that you are 7 days asymptomatic at the time of the blood draw, thus, a consultation with our doctor is required before blood sampling.
In case you have any past symptoms, our doctor will also have to document the timing and nature of those. Last, but not least, the doctor will counsel you on the limitation of the test and interpretation of results.
How Long Do Results Take?
Currently, the results are expected to be ready in 1-3 business days, however, as the test is newly developed, this may change with time. AllCare emails you as soon as our doctors interpret your results!
Is It FDA Approved?
Unfortunately, currently, there are no “FDA approved” SAR-Cov2 antibody tests available. Several assays have “Emergency Use Authorization (EUA)”. Please see the charts below for more info on the difference in performance characteristics of EUA and FDA.
