Antibody tests could tell people whether they have had the virus and are
now immune. Such tests are done by taking a blood sample and looking for
the presence of the right COVID-19 antibodies.
Rapid results – maybe in as little as 10 minutes.
Note: the antibodies-do NOT appear until four to five weeks after the
onset of symptoms. If you are currently symptomatic you should have a
PCR Swab test.
