Herpes Simplex Virus 2 Immunoglobulin G (IgG) Antibody, Qualitative or Semi-Quantitative Measurement by Serological Test (CSF)

Why This Test Might Be Ordered

Your healthcare provider may recommend this test if you have symptoms like severe headache, neck stiffness, confusion, fever, or neurological issues that could suggest a serious infection involving the brain or spinal cord. They may also order it if you have a history of HSV-2 infection or if you’re at risk for complications from the virus.

What to Expect Before the Test

No special preparation is needed for this test. A healthcare professional will collect a small amount of cerebrospinal fluid through a procedure called a lumbar puncture (spinal tap). This involves inserting a needle into your lower back to draw fluid from your spinal canal.

What to Expect During the Test

The procedure is usually done in a hospital or clinic setting. You may feel pressure or a slight ache where the needle is inserted, but it’s generally well-tolerated. You’ll lie on your side with your knees bent, and the area will be numbed with a local anesthetic.

What to Expect After the Test

After the procedure, you’ll rest for a short time to ensure there are no complications. You may experience mild soreness or a small bruise at the injection site. Stay hydrated and avoid strenuous activity for a few hours. You’ll need someone to drive you home if you’re feeling dizzy or lightheaded.
