Antibody Test

The antibody test (also called the serological test) will detect infections after the immune system has produced antibodies which recognise the virus. These antibodies will remain in the bloodstream long after the patient recovered from the virus.

Ab blood sample is taken and sent to the laboratory where they analyse the sample for the antibodies. If antibodies to the SARS-CoV-2 virus are present in the sample this indicates the donor has previously been exposed to the virus.
