Why This Biomarker Matters

A positive result indicates past or current HSV-1 infection. This helps assess immune status and may explain recurring cold sores or atypical symptoms.

Overview

This test detects IgG antibodies against herpes simplex virus type 1 (HSV-1), indicating current or past infection. HSV-1 causes cold sores and can also infect the eyes, skin, and nervous system. IgG antibodies mean you've been exposed to the virus at some point; they typically remain for life even after the infection resolves. A positive result shows immunity from prior exposure but doesn't mean you're currently contagious. This test helps assess infection history and immunity status.
