Herpesvirus 6 IGG (HHV-6)

Herpes Testing

A healthy result should fall into the range 0 - 9.99 index.

Human Herpesvirus 6 (HHV-6) has long been suspected as one trigger for Chronic Fatigue Syndrome. Human herpesvirus 6 (HHV-6) is a set of two closely related herpesviruses, HHV6-A and HHV6-B. Infection is extremely common and usually occurs at an early age. 64-83% of infants are infected by age 13 months. HHV-6 has an affinity for leukocytes and nervous tissue, especially the olfactory bulb tissues, from which it is thought to disseminate to other parts of the brain. After infection the virus remains latent but can reactivate asymptomatically even in healthy individuals.

HHV-6 has been found to activate Epstein-Barr virus from latency. Conversely, the presence of EBV renders B cells more susceptible to HHV-6 infection.
