What's this test for?

This test is ideal if you're experiencing unexplained bone pain, fatigue, frequent infections, or if a prior blood test found unusual proteins in your blood. It helps identify and monitor abnormal antibody proteins (called M proteins or M components) that can be linked to certain immune system or bone marrow conditions. It's often used as a follow-up after protein electrophoresis showed something worth investigating further.

What's included in this test?

This panel combines immunofixation, which identifies specific abnormal antibody proteins by type, with quantitative measurement of your three main immunoglobulin classes. Together, these results give a fuller picture of how your immune system's antibody production is behaving, which is especially useful for spotting and tracking unusual protein patterns over time.

What happens after I get my results?

Your results will be available in your account, with each immunoglobulin value shown alongside its normal range and a plain-language explanation. If your results show an M protein or an abnormal immunoglobulin pattern, the report will outline what that means and suggest appropriate next steps, which may include retesting in a few months to track changes over time. You can download a standard lab report directly from your account at any time, and the trends feature lets you compare results across multiple tests to see how your levels are changing. If any value comes back significantly abnormal, seek medical care promptly to discuss the finding further.

How can I naturally support healthy immune function?

While immunoglobulin levels are largely driven by underlying immune activity rather than lifestyle alone, supporting general immune health can still help. Eating a balanced diet rich in fruits, vegetables, and lean protein, staying well hydrated, getting consistent sleep, and managing stress all support healthy immune function. Avoiding smoking and excessive alcohol use is also beneficial, since both can affect antibody production.

When will I get my results?

Results for this panel are typically ready within about 7 days of your sample being processed at the lab. Because immunofixation involves a detailed lab technique to identify specific protein types, it takes a bit longer than a standard blood test. You'll receive a notification as soon as your results are ready to view in your account.

Who should consider this test?

This test is a good option for people who had an abnormal protein electrophoresis result, those with a family history of plasma cell or bone marrow disorders, or anyone experiencing symptoms like persistent fatigue, bone pain, or recurring infections without a clear cause. It's also useful for ongoing monitoring if you've previously been found to have an M protein, to track whether levels are stable, rising, or falling over time.

What symptoms indicate I may need this test?

Common signs that may prompt this test include unexplained bone or back pain, ongoing fatigue or weakness, frequent or unusual infections, and unexplained weight loss. Some people are prescribed this test after a routine blood or urine test showed an abnormal protein pattern, even without obvious symptoms. If you're experiencing several of these signs together, it's worth having your immunoglobulin levels checked.

What does a high immunoglobulin level mean?

A high level in one specific immunoglobulin class, especially when it shows up as a distinct M protein on immunofixation, can indicate that a group of similar antibody-producing cells is multiplying more than expected. This pattern is worth monitoring closely and discussing further, and the report will describe which class is elevated. Retesting on a regular schedule is often recommended to see whether the level is stable or increasing.

What does a low immunoglobulin level mean?

Low immunoglobulin levels can mean your body isn't producing enough antibodies to fight off infections effectively, which might explain frequent colds or infections that take longer to clear. This can sometimes be related to nutrition, certain medications, or how your immune system is functioning overall. If your levels come back low, it helps to note how often you get sick and how you're recovering, and to retest to confirm the trend.

How often should I retest?

If your first result is normal and you have no ongoing symptoms, retesting isn't usually needed unless new symptoms appear. If you have an abnormal result, especially an M protein, retesting every 3 to 6 months is a common approach to track whether your levels are changing. Your lab report will include guidance on a suggested retesting timeline based on your specific results.
