What's this test for?

This test is ideal if you're experiencing frequent infections, unexplained fatigue, or symptoms that suggest your immune system isn't working the way it should. It measures a specific antibody called IgM, which is one of the first defenses your body makes when it encounters a new infection or health issue. It can also help follow up on unclear results from other blood work related to your immune function.

What's included in this test?

This test focuses specifically on IgM, an antibody that plays a key early role in your immune response. Understanding your IgM level matters because it can reflect how your body is currently responding to infections, certain autoimmune conditions, or other immune-related changes, and having a clear number helps put other symptoms or lab results into context.

What happens after I get my results?

Your results will appear in your account with the normal range clearly explained so you can see exactly where your value falls. If your IgM level is outside the expected range, simple next steps like retesting in a few weeks or adjusting lifestyle habits that support immune health are usually appropriate, and you should seek medical care quickly if you have severe symptoms like high fever or ongoing infection. You can download a standard lab report directly from your account at any time. You can also track this result alongside future tests using the trends feature to see how your levels change over time.

How can I naturally support my immune system?

Getting consistent sleep, eating a diet rich in fruits, vegetables, and lean protein, and staying hydrated all help your immune system function properly. Regular moderate exercise and managing stress through activities like walking, stretching, or meditation can also make a noticeable difference. Avoiding smoking and limiting alcohol gives your body's natural defenses a better chance to work well.

When will I get my results?

Results are typically ready within about 7 days of your lab visit. Once processed, they're automatically uploaded to your secure online account, and you'll be notified as soon as they're available. You can log in anytime to view, download, or track your report.

Who should consider this test?

This test is a good fit for anyone dealing with recurring infections, unexplained fatigue, or unusual immune symptoms that haven't been explained by other testing. It's also useful if you want a clearer picture of your immune system's current activity level. People monitoring an existing immune-related condition may also find this test helpful for tracking changes.

What symptoms indicate I may need this test?

Common signs include getting sick more often than usual, infections that take longer than normal to clear up, ongoing fatigue, or swollen glands. Some people also notice joint discomfort or skin changes that don't have an obvious cause. If these symptoms are recurring or persistent, this test can help provide useful information.

What is IgM and why does it matter?

IgM is an antibody, which is a protein your immune system makes to fight off germs. It's usually the first antibody your body produces when you're exposed to a new infection, so it acts like an early warning signal. Knowing your IgM level helps show how actively your immune system is responding to something happening in your body right now.

What does a high IgM result mean?

A higher than normal IgM level often means your immune system is actively responding to a recent or current infection. In some cases, it can also be linked to certain chronic immune conditions. Simple next steps include noting any recent illnesses, staying well hydrated, and getting plenty of rest while your body works through the response, and retesting later to see if the level returns to normal.

How often should I retest?

If your first result was normal and you're not experiencing symptoms, retesting once a year or as part of routine health monitoring is generally enough. If your level was outside the normal range or you're tracking an active immune concern, retesting every few weeks to a couple of months can help you see whether things are trending in the right direction. Using the trends feature makes it easy to compare results side by side over time.
