Herpes Simplex Virus 2 Antibody, Qualitative (IgG)

Why This Test Matters

Herpes simplex virus type 2 (HSV-2) is the primary cause of genital herpes. Antibodies to HSV-2 can appear in your blood after infection, even if you don’t currently have symptoms. This test helps identify whether you’ve been exposed to the virus, which can influence decisions about treatment, pregnancy planning, or sexual health counseling.

What to Expect Before the Test

No special preparation is needed for this test. A blood sample will be drawn from a vein in your arm by a healthcare professional. You may feel a slight pinch, but it usually doesn’t cause significant discomfort.

What the Results Mean

A positive result means your blood contains antibodies to HSV-2, suggesting past or current infection. A negative result means the test did not detect these antibodies, but this does not rule out possible infection if you’ve been exposed recently. Results should always be interpreted by a healthcare provider in the context of your medical history and symptoms.

Clinical Significance

This test is often used to diagnose or confirm HSV-2 infection, especially if you have symptoms like sores, itching, or unusual discharge in the genital area. It can also be important during pregnancy to assess risks to the baby or for sexual health counseling.
