What's this test for?

This test is ideal if you're experiencing ongoing, unexplained fatigue or if you want to know whether you've been exposed to Human Herpesvirus 6 (HHV-6) in the past. HHV-6 is the virus that causes roseola infantum, a common childhood illness, and most adults have been exposed to it at some point. This test can also be useful if you're being evaluated for chronic fatigue syndrome, since HHV-6 exposure has been linked to some cases.

What's included in this test?

This test measures IgG antibodies specific to Human Herpesvirus 6, which tell you whether your immune system has encountered this virus before. IgG antibodies are markers your body produces after fighting off an infection, and they can stick around for years, sometimes for life. This single-marker test focuses specifically on past exposure rather than an active, current infection.

What happens after I get my results?

Your results will show up in your account along with an explanation of what the normal range means for this antibody. If your result comes back positive, it generally means you were exposed to HHV-6 at some point in your life, which is very common and usually not a cause for concern on its own. The full lab report is available to download from your account, and if you retest in the future, you can track your results over time using the trends feature. If you're dealing with ongoing symptoms like fatigue, consider pairing this result with other relevant testing to get a fuller picture.

How can I naturally support my immune system?

Getting enough sleep, staying hydrated, and eating a diet rich in fruits, vegetables, and whole grains all help your immune system function well. Regular moderate exercise and managing stress through activities like walking, meditation, or hobbies can also make a real difference. If fatigue is a main concern, prioritizing consistent sleep schedules and limiting caffeine and alcohol may help your energy levels over time.

When will I get my results?

Results are typically ready within about 7 days of your lab visit. Once available, you'll receive a notification and can log into your account to view the full report at any time.

Who should consider this test?

This test is a good option if you have persistent, unexplained fatigue and want to rule in or out past HHV-6 exposure as a contributing factor. It may also be helpful if you're curious about your exposure history to common childhood viruses. People being evaluated more broadly for chronic fatigue syndrome may find this test useful as part of a wider testing approach.

What symptoms indicate I may need this test?

Common reasons people consider this test include long-term fatigue that doesn't improve with rest, low energy that interferes with daily life, and general feelings of being run-down without a clear cause. Some people also test after learning a family member had roseola as a child and want to understand their own exposure history. If you've had these symptoms for six months or more, this test may offer useful information.

What does a positive result mean?

A positive IgG result means your immune system has been exposed to HHV-6 at some point, which is extremely common since most people are infected with this virus during early childhood. On its own, a positive result doesn't mean you have an active infection or that HHV-6 is the cause of any current symptoms. It simply confirms past exposure, which your body's immune system has already responded to and typically keeps in check.

How often should I retest?

Since this test looks at past exposure rather than an active infection, there's usually no need for frequent retesting. If you're using this test as part of investigating chronic fatigue, discuss with your testing plan whether periodic retesting alongside other markers makes sense for tracking your health over time. Most people only need to take this test once, since IgG antibody status doesn't typically change.

What should I do if my results are unclear or concerning?

If your fatigue or other symptoms continue after getting your results, consider looking into other possible causes such as thyroid function, nutrient deficiencies, or sleep quality through additional testing. Keep track of your symptoms and how they change over time so you have clear information if you decide to pursue further evaluation. In the rare case of severe or worsening symptoms, seek medical care promptly.
