AFC Urgent Care Stamford is offering antibody blood testing also known as SARS-CoV-2 AB to detect past infection with coronavirus.  The results are available within 2-5 days.  

What hours are you testing?

Testing is done by appointment.  Please register online at:

Who can be tested?

Only patients over the age of 15 who are asymptomatic (not exhibiting any sign or symptoms of active coronavirus infection) for at least 14 days can be tested.  

What is the difference between the antibody test and molecular COVID-19 test?

The antibody test is a blood test which tests for past infection and is very different from the molecular COVD-19 test, which is done with a nasal swab, and is checking for active presence of the COVID-19 virus itself.

How long before I get my results?

Results usually take about 2 to 5 days. This timing is based on current laboratory capacity and subject to changes/delays.

What is the cost of the test?

From what we have learned, insurance will cover the cost of the test, however, we encourage you to reach out to your carrier to be 100% certain before testing.  The CPT code for this test is 86769.  If you do not have insurance, the cost of the testing is $150.

How is the testing performed?

You will first have a consultation with our provider via a Telemedicine visit prior to being scheduled for the blood draw (antibody test.)  The provider will make sure you are asymptomatic at the time of the blood draw and document the timing and nature of past symptoms (if any).  Last but not least, the provider will counsel you on the limitations of the test and interpretation of results. 

When you come in for your blood draw, we ask that you come to the center wearing a mask. 

What laboratory are you working with to perform the testing?

This antibody test is being offered through Quest Laboratories, a leader in infectious disease testing services.  Quest is using the Abbott Architect Kit.  To learn more about the test please visit:

Is the test FDA approved?

This test is has been approved for Emergency Use Authorization (EUA) by the FDA.

What does my test result mean?

  • Negative: it means that you did not make antibodies to COVID-19 (This coupled with your negative result for acute COVID-19 infection means you have not been infected nor are you acutely infected.)
  • Positive: it means that you may have been infected with COVID-19 in the recent past and have developed antibodies.  

The CDC and US Department of Health and Human Services (HHS) have not yet issued a formal statement regarding the confirmation of the precise protection that these antibodies grant us.   Please refer to the CDC’s website for more information as decisions will be made in the future regarding the interpretation and usage of these test results. 

Please contact the center at 203-969-2000 with additional questions.
