Cellex were the first to have a serological test to detect antibodies to the COVID-19 coronavirus SARS-CoV-2 approved in the US by the FDA under emergency use authorization (EUA) on April 1, 2020. The test analyzes blood samples in authorized labs with a 15-20 minute test that detects two types of antibodies, immunoglobulin M (IgM) and immunoglobulin G (IgG). IgM is the first antibody the body makes to a foreign substance, appearing a few days after infection. The body later produces large quantities of IgG. A positive result can mean a person is currently or was recently infected with SARS-CoV-2.
