What's this test for?

This test is ideal if you're experiencing recurring infections, unexplained fevers, or frequent illnesses that suggest your immune system isn't working properly. It helps identify immune deficiencies that make you more susceptible to infections, or immune disorders where your body produces too many antibodies. Many people use this test when they notice they get sick more often than others or have symptoms that doctors can't easily explain.

What happens after I get my results?

You'll receive detailed doctor notes in simple language explaining what your IgM levels mean for your immune function and susceptibility to infections. These notes include personalized recommendations like lifestyle changes to support your immune system, supplement suggestions, or whether you should consult with an immunologist. You'll also get the standard lab report and can track your IgM levels over time using our trends feature to monitor your immune health.

What's included in this test?

This test measures Immunoglobulin M (IgM). This test measures Immunoglobulin M (IgM), which is your body's first line of antibody defense against new infections. IgM levels help reveal whether your immune system is responding properly to infections, whether you have an immune deficiency that makes you vulnerable to illness, or whether there's abnormal antibody production related to conditions like Waldenström's macroglobulinemia. This marker is crucial for understanding why you might be getting sick frequently or experiencing unexplained immune-related symptoms.

When will I get my results?

Results are typically available within 1-3 business days after your sample reaches the lab. You'll receive an email notification as soon as your results are ready to view in your secure online account. This quick turnaround helps you get answers about your immune health without a long wait.

Who should consider getting this test?

This test is important for people experiencing frequent infections, those with a family history of immune disorders, or anyone whose doctor suspects an immune system problem. It's also useful for children with recurring ear infections or respiratory issues, adults with unexplained symptoms, and people being evaluated for certain blood disorders. If you find yourself constantly fighting off illnesses while others around you stay healthy, this test can provide valuable insights.

What symptoms indicate I may need this test?

Common symptoms include getting sick more frequently than others, recurring respiratory infections, persistent fatigue that doesn't improve with rest, unexplained fevers, and chronic sinus or ear infections. You might also experience frequent digestive issues, slow healing from minor infections, or feeling run down all the time. Some people notice they catch every cold or flu that goes around, or that infections last longer than they should.

How can I naturally support my immune system?

Supporting immune health starts with getting 7-8 hours of quality sleep each night, as this is when your body produces important immune cells. Eat a varied diet rich in fruits, vegetables, and lean proteins to provide essential vitamins and minerals, especially vitamin C, vitamin D, and zinc. Regular moderate exercise, stress management through relaxation techniques, staying hydrated, and avoiding smoking and excessive alcohol can all help maintain healthy immune function.

What is Immunoglobulin M and why does it matter?

Immunoglobulin M (IgM) is the largest antibody your body makes and the first one to respond when you encounter a new infection. Think of it as your immune system's rapid response team that shows up immediately to fight off bacteria, viruses, and other invaders. Measuring IgM helps doctors understand if your immune system can properly defend you against infections, or if there's a deficiency that leaves you vulnerable to getting sick frequently.

What does low IgM mean?

Low IgM levels suggest your immune system may not be producing enough of these important first-response antibodies, leaving you more vulnerable to infections. This can occur in selective IgM deficiency, certain inherited immune disorders like Bruton's disease, or acquired immune deficiencies. People with low IgM often experience frequent bacterial infections, particularly in the respiratory tract, and may take longer to recover from common illnesses.

What does high IgM mean?

High IgM levels can indicate several conditions, including active viral or bacterial infections like mononucleosis, certain blood disorders such as Waldenström's macroglobulinemia, or kidney conditions like nephrotic syndrome. Elevated IgM may also be seen in people taking estrogen therapy or during acute immune responses. Your doctor will consider your symptoms and medical history to determine what elevated IgM means in your specific situation.
