The Herpes Simplex Virus (HSV) IgM Antibody Test is a blood test used to detect Immunoglobulin M (IgM) antibodies against the Herpes Simplex Virus (HSV), which causes both oral (cold sores) and genital herpes.
The IgM antibody is part of the body's primary immune response and is usually produced shortly after the initial exposure to the virus. Therefore, this test is primarily used as a screening tool to suggest a recent or primary (first-time) infection.
