Overview

The Human Herpes Virus (HHV) 6 - IgG and IgM Antibodies test measures HHV-6 specific IgG and IgM antibodies using a serum blood sample obtained via venous draw. These antibody markers reflect different aspects of the immune response to HHV-6 exposure.

This test may be clinically useful when symptoms such as prolonged fatigue, cognitive changes or recurrent flu-like features raise questions around viral exposure history. Reviewing IgG and IgM antibodies together allows practitioners to consider immune response patterns across different timeframes.

Practitioners typically interpret results alongside clinical history, timing of recent or past illnesses, immune-related symptoms and other laboratory findings. This helps place HHV-6 antibody patterns into context alongside the individual’s broader health picture and current concerns.
