TestSource Lab is now offering COVID-19 Antibody Testing! The test is designed to detect antibodies against the virus that causes COVID-19. Antibodies are proteins produced by the immune system in response to an infection and are specific to that particular infection. Your serum specimen obtained from the blood draw will be tested for both immunoglobulin G (IgG) and immunoglobulin M (IgM). Specimens are collected from a simple blood draw, not nasal swabs or finger pokes. Results are assigned numerically Quantitative results, not just simple “pass or fail” results. You must be symptom-free for 10 – 14 days in order for TestSource Lab to draw your blood.
