Herpes Simplex Virus (HSV) Types 1 and 2 Specific Antibodies Blood Test, IgG

What is the purpose of this test?

The Herpes Simplex Virus (HSV) Types 1 and 2 Specific Antibodies Blood Test, IgG, is designed to detect past exposure to HSV-1 and HSV-2 by measuring IgG antibodies in the blood. HSV-1 commonly causes cold sores, while HSV-2 is most often linked to genital herpes. This test helps determine if a person has developed antibodies from a past infection, even if they’ve never shown symptoms. It is especially useful because many people infected with HSV are unaware they have the virus due to mild or no symptoms.

This test offers two different reporting formats depending on the laboratory: LabCorp provides qualitative results, reported as "Abnormal/Reactive" (positive) or "Non-Reactive" (negative), which simply indicate the presence or absence of antibodies. Other laboratories may provide quantitative results, showing the specific antibody levelpresent in the blood, which may be helpful in certain clinical contexts. Understanding your herpes status can help you and your healthcare provider make informed decisions regarding treatment, transmission prevention, and overall health management.
