Also known As SARS-Cov-2 AB test checks for presence of antibodies to coronavirus in the blood. Antibody test is very different from molecular covid19 test, which is done with nasal swab, and is checking for presence of the covid-19 virus itself. Antibodies are produced by immune system approximately 10 days after onset of the infection and remain positive long after the infection. This is why antibody test can be used to detect a past infection with coronavirus.
Which Antibodies Will Be Tested?
IgG turns positive within 7-20 days of infection and tends to persist for over 6 months (likely years). IgM turns positive within 7-20 days of infection onset, peaks @ 80 days and fades away within 6 months.
Who Can Get Covid19 Antibody Test?
The primary care clinic at CLS Health is offering antibody test to asymptomatic (not exhibiting any signs or symptoms of active infection) patients only. If you have mild cough or runny nose or still recovering – we have to wait 7 days after you recover completely in order to get this test. We cannot accommodate any sick visits for covid19 (sars-cov-2) antibody blood test at this time. For above mentioned reasons, all patients will need to consult a CLS Primary Care or Pediatric physician before they can be considered for covid-19 antibody tests. Also, if you are already in our office for completely different reasons, we can offer you to get this test done on-the-spot.
Where Is the Covid19 Antibody Test Done?
CLS Health offers the blood test to asymptomatic patients at our primary care clinic. Prior to your blood draw you need a consultation with our doctor. Doctor will make sure you are 7 days asymptomatic at the time of the blood draw. Doctor will also document the timing and nature of your past symptoms (if any). Last, but not least, doctor will counsel you on limitation of the test and interpretation of results.
How Long Do Results Take?
Expected turnaround time is less than 10 minutes. Since the test is very new, this may change with time.
The COVID-19 IgM/IgG Rapid Test can be used to screen patients suspected of having been affected by the novel coronavirus. However, results of test should not be the only basis for diagnosis. Results should be used in combination with clinical observations and other testing methods such as nucleic acid PCR test. CLS is offering antibody test to asymptomatic (not exhibiting any signs or symptoms of active infection) patients only. If you have mild cough or runny nose or still recovering – we have to wait 7 days after you recover completely in order to get this test or schedule an appointment for in person or Televisit with one of our primary care or pulmonary providers. Also, if you are already in our office for completely different reasons, we can offer you to get this test done on-the-spot.
