Herpes Simplex Virus 1/2 IgG
Herpes simplex virus (HSV) IgG measures antibodies produced after exposure to HSV-1 or HSV-2. HSV-1 typically associates with oral lesions; HSV-2 with genital lesions. IgG develops weeks after first exposure and persists long-term.
Why it matters: A positive HSV IgG indicates prior exposure to one or both types. The test does not localize the infection or distinguish active from dormant phases — interpretation depends on type-specific testing and clinical context.
