Understanding Lab Tests for Waldenstrom's macroglobulinemia
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Waldenstrom's macroglobulinemia is a rare type of non-Hodgkin's lymphoma that affects white blood cells called B-lymphocytes. This condition is characterized by the overproduction of an abnormal protein called immunoglobulin M (IgM), which can be detected through specialized blood testing.
Recommended Test
Protein Electrophoresis, with Total Protein and Reflex to IFE, Serum
This comprehensive test analyzes the pattern of proteins in the blood and can detect the abnormal increase in IgM protein that is characteristic of Waldenstrom's macroglobulinemia. The test includes immunofixation electrophoresis (IFE) which provides additional detail to identify the specific type of abnormal protein, making it a crucial diagnostic tool for this type of non-Hodgkin's lymphoma.

How Blood Tests Help Diagnose Waldenstrom's macroglobulinemia
The hallmark of Waldenstrom's macroglobulinemia is the presence of abnormal amounts of IgM protein in the blood. Blood tests that analyze protein patterns are essential diagnostic tools that can reveal the characteristic protein abnormalities associated with this condition, helping healthcare providers make an accurate diagnosis.
Understanding the Results
In Waldenstrom's macroglobulinemia, protein electrophoresis typically shows an abnormal spike or increase in the gamma region where immunoglobulins are found, specifically representing elevated IgM levels. The reflex to immunofixation electrophoresis helps confirm and characterize this abnormal protein pattern, providing essential information for diagnosis and monitoring.
Important Considerations
The information here is for educational purposes only and is not a substitute for professional medical advice. Diagnosis of Waldenstrom's macroglobulinemia typically requires additional testing including bone marrow biopsy and other specialized studies. Always consult with a healthcare provider for proper diagnosis and treatment.
