May be significant: Immunogloblin m (igm) is one of the 5 classes of proteins that have antibodies. C4 is part of the complement cascade, a series of proteins that are important in immunity and inflammation. Elevation of both may occur in various diseases. The significance of the specific values for you depends on what your clinical problem is. Therefore, i can not be more specific as to what it means for you.

A 36-year-old member asked:

What does high immunoglobulin IG m and complement mean?

Depends: The "normal ranges" for all lab tests include 95% of the "normal" population; thus, 2.5% of people are above the upper limit, and 2.5% are below the lower limit. There's nothing to worry about if your values are a little bit above the normal range, but a very elevated IgM could be a sign of a problem. You need to check with the physician who ordered the tests to interpret your results.
