How does a SARS covid-19 antibody test work?
SARS-CoV-2 antibody (often referred to as serology) tests look for antibodies in a sample to determine if an individual has had a past infection with the virus that causes COVID-19. COVID-19 antibody tests can help identify people who may have been infected with the SARS-CoV-2 virus or have recovered from a COVID-19 infection.
How long does it take for antibodies to show up?
A: Antibodies are proteins made by the immune system to fight infections like viruses and may help to ward off future occurrences by those same infections. Antibodies can take days or weeks to
Where can I get an antibody test done?
A: Antibody and diagnostic tests are available by prescription from a health care provider and may be available at local health care facilities and testing centers.
