Herpes Simplex Virus (HSV) Antibody Detection by Probe-Based Immunoassay

What This Test Measures

The test detects specific antibodies produced by your immune system in response to HSV. These antibodies indicate whether you have been exposed to HSV at some point in your life, even if you don’t currently have symptoms. The presence of these antibodies suggests immunity or past infection, but they do not distinguish between HSV-1 or HSV-2 specifically without additional testing.

Why It’s Ordered

Your healthcare provider may order this test if you have had symptoms of HSV (such as sores, itching, or burning), if you’ve been exposed to someone with HSV, or if you’re experiencing recurrent outbreaks. It can also be used for screening in certain high-risk groups or before certain medical procedures.

Sample Collection and Process

A blood sample is typically collected from a vein in your arm. The blood is processed to separate serum (the liquid part containing antibodies) for testing. The test uses a probe-based immunoassay, which detects the presence of HSV antibodies in your serum with high sensitivity.

What to Expect Before the Test

No special preparation is needed for this test. You may have some mild discomfort from the needle, but this usually goes away quickly. If you’re on blood-thinning medication or have a history of bleeding disorders, let your provider know before the test.
