What's this test for?

This test is ideal if you're experiencing unexplained fevers, skin rashes, or want to understand a past viral illness. It checks for antibodies to Human Herpesvirus 7 (HHV-7), a common virus that can cause a childhood illness called roseola (exanthem subitum) marked by fever followed by a rash. It's also useful if you're investigating recurring symptoms that haven't been explained by other testing.

What's included in this test?

This test measures IgG antibodies against Human Herpesvirus 7 using an immunofluorescence assay (IFA) method. IgG antibodies matter because they show whether your immune system has encountered this virus before, helping distinguish a past infection from a current one when looked at alongside symptoms.

What happens after I get my results?

Your results will appear in your online account, with each value's normal range clearly explained so you know exactly what it means. If your results show a past or recent HHV-7 infection, next steps usually involve simple symptom management since most people have already been exposed and built immunity, but you should seek medical care right away if you have a high fever, severe rash, or other concerning symptoms. You can download the full standard lab report from your account at any time, and if you retest in the future, the trends feature lets you track your antibody levels over time.

How can I naturally support my immune system against viral infections?

Getting consistent sleep, eating a diet rich in fruits, vegetables, and lean protein, and staying hydrated all help your immune system respond well to viral exposures. Reducing stress through activities like walking, stretching, or meditation can also support healthy immune function. Avoiding smoking and limiting alcohol gives your body's natural defenses a better chance to work efficiently.

When will I get my results?

Results are typically ready within about 7 days of your lab visit. Once ready, they'll be uploaded directly to your secure online account where you can view and download them anytime.

Who should consider this test?

This test is a good fit for anyone with a history of unexplained fever and rash episodes, especially if you want clarity on a past childhood illness. It can also be helpful for people with weakened immune systems who want to check their exposure history to common viruses. If you're simply curious about a past illness or had symptoms that were never fully explained, this test can offer useful answers.

What symptoms indicate I may need this test?

Common signs include a sudden high fever followed by a pink or red rash, especially in young children, though adults can be affected too. Other symptoms can include mild fatigue, swollen lymph nodes, or irritability during the initial infection. If you've had these symptoms in the past and want confirmation, or if you're currently experiencing them, this test can help provide answers.

What does a high antibody level mean?

A high IgG antibody level generally means your body has been exposed to HHV-7 at some point and built up immunity against it, which is very common since most people are infected during early childhood. It does not necessarily mean you're currently sick, since IgG antibodies can stay in your system long after the initial infection clears. If you have active symptoms alongside high antibody levels, monitor them and seek medical care if they worsen or don't improve.

How often should I retest?

Since HHV-7 antibody levels reflect past exposure and don't typically change quickly, most people don't need to retest unless they're investigating a new bout of symptoms. If you're monitoring immune status due to a health condition, retesting every 6-12 months may be reasonable. Otherwise, this is usually a one-time test to establish exposure history.

What should I do if my results are abnormal?

If your results indicate an active or recent infection, focus on rest, hydration, and monitoring your symptoms since most cases resolve on their own. Keep track of any fever, rash, or fatigue and note how long they last using the trends feature in your account. Seek medical care immediately if you develop a very high fever, difficulty breathing, or a rash that spreads rapidly or looks unusual.
