What this test is
This test looks for HSV-2 antibodies in a blood sample. Antibodies are proteins the immune system produces after exposure to the virus. The test does not detect the virus itself; it detects the immune response to it.
What it measures
- HSV-2 IgG antibodies — Reflects past or current exposure to herpes simplex virus type 2
- HSV-1 IgG antibodies (if included) — May be tested separately to distinguish between HSV-1 and HSV-2
- Index value — A numerical result that helps the lab classify the test as positive, negative, or equivocal
What the test involves
A healthcare worker collects a small sample of blood from a vein in your arm using a standard blood draw. The sample is then sent to a laboratory for analysis.
Why it is often ordered
A clinician may order this test if you have symptoms that could be related to genital herpes or if you want to know whether you have been exposed to HSV-2. It is also sometimes used when a partner has genital herpes or when someone has other risk factors.
Preparation
No special preparation is usually needed for this blood test. Follow any specific instructions provided by the collection lab or your healthcare provider.
How results are reported
Results are typically reported as positive, negative, or equivocal based on a cutoff value set by the laboratory. Reference ranges and interpretation can vary between laboratories, so your clinician will explain what your result means for you.
