What's this test for?

This test is ideal if you're experiencing fever, chills, headache, muscle aches, or an unexplained rash after a tick bite or spending time in wooded or grassy areas. It helps check for ehrlichiosis, a tickborne illness that can be mistaken for a common flu or other tick-related infections. This is especially useful if you live in or traveled through the eastern, southeastern, or south-central United States, where this disease is more common.

What happens after I get my results?

Your results will show up in your account with the normal reference range explained for each antibody measured, so you can see exactly what your numbers mean. If your results are positive or unclear, retesting a few weeks later can help confirm whether antibody levels are rising, which supports a more accurate picture of infection timing. If you have severe symptoms like high fever, confusion, or difficulty breathing, seek medical care right away rather than waiting on results. You can download a standard lab report from your account anytime, and use the trends feature to track your antibody levels if you test again in the future.

What symptoms indicate I may need this test?

Common warning signs include fever and chills, headache, fatigue, muscle or joint pain, nausea or other stomach issues, and sometimes a skin rash. These symptoms typically show up within one to two weeks after a tick bite. Because these symptoms overlap with other tickborne illnesses like Lyme disease or anaplasmosis, testing helps narrow down the cause.

How can I naturally support recovery from a tickborne infection?

While antibody testing helps identify past or recent exposure, supporting your body during recovery can include staying well hydrated, getting extra rest, and eating a balanced diet rich in fruits, vegetables, and lean protein to support your immune system. Gentle movement like walking can help with fatigue once symptoms start improving. These steps support general recovery but are not a substitute for prompt attention to worsening or severe symptoms.

When will I get my results?

Results are typically ready within about 7 days from when your sample is processed at the lab. Because this test looks at antibody patterns, timing matters, so results are most useful when collected at the right point after symptom onset. You'll receive an email notification as soon as your results are ready to view in your account.

Who should consider this test?

This test is a good fit for anyone who has had a known tick bite or exposure to tick habitats and is now experiencing flu-like symptoms. It's also useful for people in high-risk regions of the U.S. who want to rule out ehrlichiosis as the cause of ongoing unexplained symptoms. People who have already been treated for a suspected tickborne illness may also use this test to check antibody patterns.

What does a positive IgM result mean?

A positive IgM result suggests your body has been making antibodies in response to a fairly recent exposure to the Ehrlichia bacteria, since IgM tends to appear early in infection. However, IgM can sometimes stay elevated for many months after the illness has cleared, so a positive result alone doesn't always mean you have an active infection. The report explains what your specific pattern of IgG and IgM together may suggest.

What does a positive IgG result mean?

A positive IgG result usually means your immune system encountered the Ehrlichia bacteria at some point, which could be a recent or a past infection from months or even years ago. IgG antibodies tend to stick around long after symptoms are gone, so this result is more about confirming past exposure than pinpointing an active infection. Looking at IgG together with IgM and your symptom timeline gives the clearest picture.

How often should I retest?

If your first test is negative but symptoms continue, retesting about 2 to 4 weeks later can help catch a rising antibody response, since early infection sometimes doesn't show up right away. If you were previously positive and want to track how your antibody levels change over time, spacing retests by a few weeks to months is reasonable. Use the trends feature in your account to compare results side by side.

What should I do if my results are abnormal?

If your results come back positive or show a pattern suggesting recent infection, pay close attention to your symptoms and consider retesting to see if antibody levels are changing over time. Keep track of any new or worsening symptoms like high fever, severe headache, or rash, and seek medical care promptly if these become severe. Simple supportive steps like rest, hydration, and good nutrition can help while your body recovers.
