What's this test for?

This test is ideal if you're experiencing frequent infections, recurring illnesses, or unexplained symptoms that suggest your immune system isn't working properly. It helps identify immune deficiencies, chronic inflammatory conditions, and can explain why you might be getting sick more often than usual. Many people use this test when they have persistent health issues, allergies, sensitivities, or gastrointestinal problems that may be linked to immune function.

What happens after I get my results?

You'll receive detailed doctor notes in simple language explaining what your immunoglobulin levels mean for your immune health and ability to fight infections. These notes include personalized recommendations like dietary changes, supplement suggestions for immune support, or whether you should see an immunologist for further evaluation. You'll also get the standard lab report and can track your immune markers over time using our trends feature to monitor how interventions or treatments are working.

What's included in this test?

This panel measures IgA (Immunoglobulin A), IgG (Immunoglobulin G), and IgM (Immunoglobulin M). This panel measures three essential antibodies that work together to protect your body from infections: IgA, IgG, and IgM. IgA primarily guards your respiratory and digestive tracts, IgG provides long-term immunity against viruses and bacteria, and IgM responds quickly to new infections. Together, these measurements reveal whether your immune system is functioning properly, overactive from chronic inflammation, or weakened by immunodeficiency.

When will I get my results?

Most immunoglobulin panel results are available within 2-4 business days after your blood sample reaches the lab. You'll receive an email notification as soon as your results are ready to view in your secure online account. More complex cases or unusual findings may occasionally take a bit longer for thorough analysis.

Who should consider getting this test?

This test is important for anyone experiencing frequent infections like colds, sinus infections, or respiratory illnesses that don't seem to go away. It's also valuable for people with chronic digestive issues, persistent fatigue, allergies that aren't responding to treatment, or a family history of immune disorders. Children with recurrent ear infections or adults with unexplained inflammatory conditions may also benefit from this evaluation.

What symptoms indicate I may need this test?

Common signs include getting sick more frequently than others around you, infections that last longer than usual or are more severe, recurring sinus or ear infections, persistent diarrhea or digestive problems, and chronic fatigue that doesn't improve with rest. You might also notice frequent allergic reactions, slow wound healing, or feeling run down all the time despite adequate sleep and nutrition.

How can I naturally support my immune system?

Focus on eating a nutrient-rich diet with plenty of colorful fruits and vegetables, lean proteins, and probiotic foods like yogurt and fermented vegetables to support gut health where much of immunity originates. Prioritize 7-9 hours of quality sleep each night, manage stress through meditation or gentle exercise, and stay hydrated throughout the day. Regular moderate exercise, vitamin D supplementation if deficient, and avoiding excessive alcohol and processed foods can also strengthen immune function.

What are immunoglobulins and why do they matter?

Immunoglobulins, also called antibodies, are proteins your immune system produces to identify and neutralize harmful invaders like bacteria, viruses, and toxins. They're your body's defense system, with each type playing a specific role in protecting different areas and responding to various threats. When immunoglobulin levels are too low, you're more vulnerable to infections; when they're too high, it may signal chronic inflammation, autoimmune conditions, or certain blood disorders.

What does low immunoglobulin mean?

Low immunoglobulin levels indicate immunodeficiency, meaning your body may not be producing enough antibodies to effectively fight infections. This can be inherited or acquired, and explains why you might experience frequent, severe, or prolonged illnesses. People with low immunoglobulins often need closer medical monitoring, may benefit from immunoglobulin replacement therapy, and should take extra precautions to avoid exposure to infections.

What does high immunoglobulin mean?

Elevated immunoglobulin levels often indicate your immune system is chronically activated, which can occur with ongoing infections, autoimmune diseases, chronic inflammatory conditions, or certain liver diseases. In some cases, very high levels may suggest lymphoproliferative disorders like multiple myeloma or lymphoma, which is why further evaluation is important. Your doctor will consider your symptoms, medical history, and other test results to determine the underlying cause.
