Herpes Blood Test (HSV-2 IgM Antibody)

This blood test detects IgM antibodies against herpes simplex virus type 2 (HSV-2), the virus most commonly associated with genital herpes. It is intended for individuals who want to investigate possible recent or active HSV-2 infection, particularly when symptoms such as genital sores, blisters, or discomfort are present, or when there has been a known or suspected exposure.

IgM antibodies are typically the first type of antibody the body produces after encountering a virus, so their presence can suggest a recent infection. However, IgM responses can sometimes be triggered by other herpes viruses or may persist, so results are best interpreted alongside your clinical history and, where appropriate, additional testing. This test is not a routine screening tool for people without symptoms or exposure risk.

Why it matters
Genital herpes is common and often manageable, but knowing your status helps you take control of your health. A positive or negative result can guide conversations with your doctor about confirmatory testing, symptom management, and steps to protect partners. Early clarity supports timely clinical advice and informed decisions about your sexual health.
