The Herpes Simplex Virus (HSV) IgG Antibody Test is a highly specific blood test offered by Augmentum Diagnostics to determine if an individual has been previously infected with the Herpes Simplex Virus (HSV), which causes both oral (cold sores) and genital herpes. This test detects Immunoglobulin G (IgG) antibodies, which are the long-term markers of the body's immune response to the virus.
