What's this test for?

This test is ideal if you're experiencing unexplained fever, swollen lymph nodes, or fatigue that won't go away, especially if your immune system is weakened. It's also useful if you've had a recent organ or stem cell transplant and need to check for viral reactivation. The test looks for genetic material from HHV-6 directly in your blood, giving a clear answer about active infection.

What's included in this test?

This test uses a single, highly sensitive method that detects the virus's genetic material directly, so it can catch an infection earlier and more accurately than older antibody-based methods. Since HHV-6 can hide in the body and reactivate later, this direct DNA detection approach is especially helpful for confirming active infection rather than just past exposure.

What happens after I get my results?

Your results will show up in your account with the normal range explained so you know exactly what your number means. If your result comes back positive, next steps usually involve retesting to track how the virus level changes over time, since a rising or falling amount matters more than a single number. A downloadable lab report is available in your account, and you can use the trends feature to watch your levels over multiple tests. If your result is significantly elevated and you feel unwell, seek medical care right away.

How can I naturally support my immune system while managing a viral infection?
Getting enough sleep, staying hydrated, and eating a diet rich in fruits, vegetables, and lean protein all help your immune system function at its best. Reducing stress through activities like walking, meditation, or light exercise can also support your body's ability to fight off viral activity. Avoiding alcohol and smoking gives your immune system one less thing to deal with while it works.
When will I get my results?
Results are typically ready within about 7 days of your sample being processed at the lab. You'll get a notification once your report is available in your account, so there's no need to call or check in manually.
Who should consider this test?
People with weakened immune systems, such as those who've had a transplant or are on immune-suppressing medication, are often good candidates for this test. It's also useful for anyone with symptoms like persistent fever, rash, or swollen glands that doctors haven't been able to explain through other testing. Parents of young children with unexplained high fevers may also find this test relevant, since HHV-6 commonly causes roseola in infants.
What symptoms indicate I may need this HHV-6 test?
Common signs include a high fever that comes on suddenly, followed by a skin rash, especially in young children. In adults, especially those with weaker immune systems, symptoms can include fatigue, swollen lymph nodes, and general flu-like discomfort that lingers. If these symptoms show up after a transplant or during immune-suppressing treatment, this test can help confirm what's going on.
What is HHV-6 and why does it matter?
HHV-6 is a common virus that most people are exposed to in early childhood, often causing a mild illness called roseola. For most healthy people it stays inactive for life, but in people with weakened immune systems, it can reactivate and cause more serious problems like fever, organ inflammation, or nervous system issues. Knowing whether it's active helps guide decisions about rest, monitoring, and further care.
What does a high HHV-6 viral load mean?
A high result means there's a large amount of viral genetic material in your blood, which usually points to an active infection or reactivation rather than a past, resolved one. This is especially important to know if your immune system is compromised, since higher levels are linked to more active viral activity. Retesting helps show whether the level is going up, staying steady, or coming down over time.
How often should I retest for HHV-6?
If you're being monitored after a transplant or during immune-suppressing treatment, retesting every few weeks is common to catch reactivation early. If you had a positive result and are otherwise healthy, retesting after a few weeks can help confirm whether the virus has cleared. Your specific retesting schedule may depend on your symptoms and immune status.

What this means

A 'Not Detected' result means no HHV-6 viral DNA was found in your blood sample, which is the expected result for most healthy people. A 'Detected' result means the virus is actively present and reproducing in your body, which is more significant if your immune system is weakened.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More advanced tests may take longer due to complexity.
