What Does This Test Measure?

The test detects IgG antibodies against HSV-2, which your immune system produces after infection. These antibodies stay in your blood for years, even after the active virus has cleared.

Why Might You Need This Test?

A doctor may recommend this test if you have symptoms like sores, pain, or unusual discharge in the genital area, or if you’ve had multiple sexual partners. It can also be used for screening during pregnancy or for diagnosing recurrent outbreaks.

What to Expect Before the Test

No special preparation is needed. A blood sample will be taken from a vein in your arm. You may feel a slight pinch, but it usually takes only a few minutes.

What to Expect After the Test

You can return to your normal activities immediately. There may be mild bruising or soreness at the injection site, but this usually goes away within a day or two.
