THE POTENTIAL AND DILEMMA OF ANTIBODY TESTING FOR COVID -19 As the world waits for the end of the COVID-19 pandemic, antibody testing has attracted much attention. Scientists across the world have developed different antibody tests, but a lot remains unclear about how to interpret these antibody tests. Antibodies are proteins produced by the immune system to fight infection. They work by binding and blocking proteins needed to infect a human cell.

Therefore, experts caution that current antibody tests should not be used to say someone is immune or fully protected from re-infection.

Antibody tests essentially use an antigen, which imitates a part of the virus, as bait. A signal registers whether antibodies have taken the bait.
