Antibody (or immunoglobulin), is a protective protein produced by the immune system whenever any unknown substance (germs, viruses) enters in the body. It works for dismissal of the unknown substance from the body in order to keep the body healthy. The Antibody test proclaims the presence of antibodies in the body and states that the body has acquired immune response with virus. The test is carried out on the blood sample. At present, we offer two types of COVID-19 Antibody tests, COVID-19 Total Antibody Test and COVID-19 IgG Antibody Test.
