COVID-19 Antibody $75
Detect prior infection and prior immunization
Testing for past infections is also known as serologic testing or antibody testing. It analyzes a sample of your blood to see if there are antibodies to SARS-CoV-2. Antibodies are a protein that the immune system makes to help identify and defend against pathogens like viruses. It generally takes several weeks for some antibodies to develop, so these tests are usually not effective for detecting active infections.
