What's this test for?

This test is ideal if you're experiencing an unexplained fever, skin rash, swollen glands, or fatigue and want to find out if a Herpesvirus 6 (HHV-6) infection is the cause. It's also useful if you've been exposed to someone with a confirmed HHV-6 infection and want to check whether you have a recent or active case. Many people carry this common virus without knowing it, so testing helps clarify whether your current symptoms are related to it.

What happens after I get my results?

Your results will show up in your account with an explanation of what a positive or negative IgM result means, so you don't have to guess what the numbers mean. If your result is positive, simple next steps include resting, staying hydrated, and managing fever or discomfort while your body clears the infection; if symptoms are severe or you develop a high fever that won't go down, seek medical care right away. A standard lab report is available to download from your account whenever you need it. You can also use the trends feature to track this result over time if you get retested later.

Who should consider this test?

This test is a good fit for anyone with unexplained fever, rash, or swollen lymph nodes, especially if a household member or close contact has been diagnosed with HHV-6. It's also useful for people with weakened immune systems who want to catch an active infection early. If you've had mono-like symptoms but tested negative for other common viruses, this test can help narrow things down.

What symptoms indicate I may need this test?
Common signs include a sudden high fever, a pink or red rash (especially in young children, where it's known as roseola), swollen lymph nodes, and general fatigue or irritability. Adults may experience fever, headache, and tiredness without the classic rash. If these symptoms show up after known exposure to someone infected, testing can confirm whether HHV-6 is the cause.
When will I get my results?
Results are typically ready within about 7 days of your lab visit. Once processed, they're posted directly to your online account, where you can view and download them at your convenience.
How can I naturally support my immune system while fighting this virus?
Getting extra sleep, drinking plenty of fluids, and eating nutrient-rich foods like fruits, vegetables, and lean protein all help your body fight off the virus faster. Reducing stress and avoiding strenuous exercise while you're feeling unwell also gives your immune system room to work. Over-the-counter fever reducers can help with comfort, but always follow the dosing instructions on the label.
What is Herpesvirus 6 and why does it matter?
Herpesvirus 6 (HHV-6) is a very common virus that most people are exposed to in early childhood, often causing a mild illness called roseola. It matters because, like other herpesviruses, it can stay dormant in your body and occasionally reactivate, which can be a concern for people with weakened immune systems. Knowing whether you have a current, recent, or past infection helps put your symptoms into context.
What does a positive IgM result mean?
A positive IgM result usually means you have a recent or active HHV-6 infection, since IgM antibodies are typically the first ones your body makes when fighting a new infection. This is common in young children experiencing their first exposure to the virus, but it can also happen in adults. If you're not in a high-risk group, a positive result often just means your body is actively responding and will clear the virus with time.
How often should I retest?
Most people don't need to retest unless symptoms persist, worsen, or return after they seemed to go away. If you have a weakened immune system, periodic retesting during periods of illness can help track whether the virus has reactivated. Otherwise, once your symptoms resolve, retesting usually isn't necessary.
What should I do if my results are abnormal?
If your IgM result is positive, focus on rest, hydration, and symptom relief while your immune system fights the infection, and monitor for any worsening signs like a very high or prolonged fever. If you have an underlying health condition or a weakened immune system, treat any high fever or unusual symptoms as a reason to seek medical care promptly. For most healthy people, symptoms resolve on their own within one to two weeks.
