Why This Biomarker Matters

Presence of HSV-2 antibodies in CSF indicates central nervous system infection requiring urgent antiviral treatment to prevent serious complications.

Overview

This test detects IgG antibodies to herpes simplex virus 2 (HSV-2) in serum or plasma. IgG antibodies indicate past or ongoing HSV-2 infection and typically develop within 2-12 weeks after initial exposure. A positive result confirms prior HSV-2 exposure, though it does not distinguish between active and latent infection. Type-specific glycoprotein G-based assays are recommended for accurate differentiation from HSV-1. This test is useful for confirming genital herpes in patients with atypical presentations and for screening sexual partners of known HSV-2-positive individuals.
