AFC Urgent Care Marlborough/Natick is able to perform coronavirus antibody testing on asymptomatic patients. Performed on a blood sample, the test can detect past infection with coronavirus with results available within 48 hours.
Who is eligible for antibody testing?
Adult patients who have been asymptomatic for at least 14 days can schedule an appointment for antibody testing. Patients who are tested for coronavirus antibodies must not be exhibiting a fever, cough or congestion.
What is the difference between diagnostic testing and antibody testing?
Diagnostic testing, or PCR testing, is performed via a nasal swab to detect the presence of the active COVID-19 virus. AFC Urgent Care Marlborough performs diagnostic testing on a drive-up basis after patients are screened via a telemedicine visit to review your symptoms. While antibody testing does require a telemedicine screening, it is performed via a blood draw and requires coming into our center. Antibody testing is only able to detect antibodies developed from a past infection.
How your results may be interpreted
Regardless of the results of your antibody test, it is critical to maintain social distancing and following current health and safety guidelines including stay-at-home orders, wearing masks in public and washing your hands frequently to remove germs.
A positive result indicates exposure to coronavirus and the development of antibodies against it. The effectiveness of the antibodies against further infection is still being researched by doctors and scientists. Please check the CDC website for regular updates on how antibody testing is being interpreted.
A negative antibody test result indicates that you have not been exposed to coronavirus. However, you may have been exposed too recently for antibodies to develop.
