Imunoglobulins IGA, IgG normal. IgM low- 44- normal 63-277. tested by Rheumatologist based on joint pain and Raynards. What is significance?

Occasionally seen. Low value here of uncertain significance. Occasionally seen in normal people. IgM typically appears early in the adaptive antibody response to infections. It has addition attributes that distinguish it from the other antibodies, but not sure that it helps in this instance, looking at autoimmune (or "over active" immune) conditions. Suggest run it by another rheumatologist here at HealthTap.
