HERPES SIMPLEX VIRUS I (HSV)-IgG Detail

The HSV IgG test is a serological blood test that detects IgG antibodies specific to Herpes Simplex Virus (HSV), typically type 1 (HSV-1) and type 2 (HSV-2). A positive IgG result indicates past infection and the presence of long-term immunity or viral latency.

• HSV-1 is commonly associated with oral herpes (cold sores), while

• HSV-2 is more often linked to genital herpes, although both can infect either area.

This test is helpful in:

• Determining prior exposure to HSV in asymptomatic individuals

• Screening in prenatal care to assess risk to the fetus

• Differentiating between HSV-1 and HSV-2 infections

It is important to note that the test does not detect recent infections. For suspected recent or active infection, an HSV IgM test or viral culture/PCR is recommended.
