What you can expect

To conduct an antibody test for COVID-19, typically a health care professional takes a blood sample, usually by a finger prick or by drawing blood from a vein in your arm. Then the sample is tested in a lab to determine whether you've developed antibodies against the COVID-19 virus.

COVID-19 antibody test results may be ready the same day as your test at some sites. Other places may have to send test samples out to a lab for analysis, so results may not be available for a few days.
