Simple blood test to check for measles immunity.
Viral antibody testing detects whether you have been exposed to specific viruses by measuring the antibodies your immune system produced in response. IgM antibodies indicate recent or active infection, while IgG antibodies indicate past exposure and potential immunity. Common tests include Epstein-Barr virus (EBV, which causes mononucleosis), cytomegalovirus (CMV), varicella-zoster (chickenpox), and measles/mumps/rubella. These tests are used to diagnose active infections, confirm immunity from past infection or vaccination, and investigate chronic fatigue or unexplained symptoms. EBV testing is particularly relevant for longevity medicine, as reactivation of latent EBV has been linked to chronic fatigue syndrome and autoimmune conditions.
