Herpes Simplex Virus (HSV) Types 1/2, IgG Previous Exposures Test
This is the test to take if you want to determine if you have been exposed to herpes in the past. The Herpes Simplex Virus (HSV) Types 1/2, IgG lab test is used in the detection of IgG antibodies to either HSV-1 and/or HSV-2.
Conventional HSV-1 and HSV-2 assays cannot differentiate HSV type 1 from HSV type 2 infection due to the extensive homology of viral antigens. Antibodies formed against either virus are highly cross reactive. An HSV-2 type-specific IgG assay based on glycoprotein G-2 is available for differentiating HSV-1 from HSV-2 infections.
