Human Herpesvirus 6 (HHV-6) DNA in Whole Blood by Nucleic Acid Amplification (Qualitative)

Why This Test Might Be Ordered

Your healthcare provider may recommend this test if you have symptoms like fever, rash, or fatigue that could be related to HHV-6 infection. It may also be used to monitor immune function, diagnose certain conditions, or investigate unexplained illnesses, especially in people with weakened immune systems or specific medical histories.

What to Expect Before the Test

No special preparation is usually needed. You may have a simple blood draw from a vein in your arm. If you are pregnant, breastfeeding, or have certain medical conditions, let your provider know before the test.

What the Test Results Mean

A positive result means HHV-6 DNA was detected in your blood sample. This does not necessarily mean you are currently ill, but it indicates the virus is present. A negative result means the virus was not detected in this sample. Follow-up testing or additional information from your healthcare provider may be needed to interpret results fully.

Common Reasons for Testing

HHV-6 is often studied in the context of conditions like severe immune deficiencies, transplant patients, or those with chronic fatigue syndrome. It may also be checked in cases of unexplained fevers, neurological symptoms, or after exposure to the virus.
