In multiple myeloma, plasma cells produce abnormally high amounts of specific antibodies. Here's what's typically seen:

• About 50% of myeloma patients have abnormally high IgG levels
• Approximately 20% have abnormally high IgA levels
• IgM myeloma is very rare Doctors use several tests to measure these levels:

• Immunofixation electrophoresis (IFE) - Shows which specific type of abnormal antibody is present
• Quantitative immunoglobulins test - Measures overall antibody levels in blood
• 24-hour urine tests - Can detect abnormal proteins that may not show up in blood tests

These measurements help doctors diagnose myeloma, plan treatments, and monitor disease progression. IgA myeloma typically has a worse prognosis than IgG myeloma, which may influence treatment decisions.
