Human Herpesvirus (HHV) 6 PCR, Quant

This test looks for Human Herpesvirus 6 (HHV-6) by screening for viral DNA in the blood. HHV-6 is a member of the Herpes family of viruses. Information on how HHV-6 is spread is limited but research has found that the majority of people are infected when they are very young. The most common form of transmission is through saliva but it can be transmitted through sexual contact as well. Once a person is infected, the virus remains in their system for the rest of their life. The virus will typically remain latent but can reactivate later in life and may be related to a variety of health issues, especially in people whose immune systems are compromised.

HHV-6 does not usually cause any symptoms but initial infection in children may cause fever, diarrhea or rash. Adults with a reactivated infection may experience fever or illness similar to mononucleosis (mono). HHV-6 has been linked to a number of conditions including Multiples Sclerosis, Viral Hepatitis, Epilepsy, Chronic Fatigue Syndrome, Encephalitis and Lung disease.

This test looks for HHV-6 viral DNA. Results are quantitative, meaning they provide a numerical value. An active infection will typically cause elevated results for viral levels. This test can help determine if a person has an active infection and monitor treatment.

Turnaround for the HHV 6 PCR is typically 7-10 business days.
