High IgA levels can indicate multiple myeloma, where cancerous plasma cells produce abnormal amounts of antibody proteins. In myeloma, these abnormal proteins (called M proteins) are produced in excessive quantities, disrupting normal immune function.

High IgA levels can indicate multiple myeloma, where cancerous plasma cells produce abnormal amounts of antibody proteins. In myeloma, these abnormal proteins (called M proteins) are produced in excessive quantities, disrupting normal immune function.
It's important to note that IgA myeloma often has a different prognosis compared to other types. People with IgA myeloma tend to have lower survival rates and a higher risk of relapse compared to those with IgG myeloma. Doctors use several tests to measure IgA levels:
- Immunofixation electrophoresis (IFE) - identifies the type of abnormal protein
- Quantitative immunoglobulins test - measures specific levels in blood
- SPEP and UPEP tests - track disease progression
Your healthcare team will consider your complete medical history and other factors when interpreting these results, as various conditions can affect protein levels.
