Waldenstrom's macroglobulinemia is a rare type of non-Hodgkin's lymphoma affecting white blood cells called B-lymphocytes. It is caused by cancerous B-lymphocytes that overproduce an abnormal protein called immunoglobulin M (IgM), which accumulates in the blood and can cause symptoms like fatigue, bleeding, and vision problems. The Protein Electrophoresis with Total Protein and Reflex to IFE, Serum is the most important test for diagnosing this condition because it detects the characteristic abnormal IgM protein spike.

Waldenstrom's macroglobulinemia is caused by cancerous B-lymphocytes (a type of white blood cell) that grow uncontrollably in the bone marrow and produce excessive amounts of abnormal immunoglobulin M (IgM) protein. These malignant cells accumulate in the bone marrow and lymph nodes, crowding out healthy blood cells. The abnormal IgM protein thickens the blood, which can lead to symptoms like fatigue, bleeding problems, vision changes, and increased risk of infections. While the exact trigger for this cancer is unknown, genetic mutations in the MYD88 and CXCR4 genes are found in most patients with this condition.
The Protein Electrophoresis with Total Protein and Reflex to IFE, Serum is the most important blood test for Waldenstrom's macroglobulinemia because it detects the characteristic abnormal spike in IgM protein levels that defines this condition. This test analyzes the pattern of all proteins in your blood and identifies the specific type of abnormal protein through immunofixation electrophoresis (IFE). When elevated IgM is detected, your doctor will typically follow up with additional tests including a bone marrow biopsy to examine the cancerous B-lymphocytes directly, complete blood count to check for anemia, and serum viscosity testing to measure blood thickness. The protein electrophoresis test is essential as the first step in diagnosis and is also used to monitor disease progression and treatment response over time.
You should get tested if you experience unexplained fatigue that does not improve with rest, frequent nosebleeds or bleeding gums, vision problems like blurred vision or blind spots, numbness or tingling in your hands and feet, or recurrent infections. Testing is also important if you have been told you have an elevated protein level on routine blood work, have unexplained weight loss, or notice swollen lymph nodes in your neck, armpits, or groin. Because Waldenstrom's macroglobulinemia is more common in people over 60 and in men, older adults with these symptoms should be especially vigilant about getting tested promptly.

What this means
Your total protein level is slightly below the optimal range. While this is often not concerning on its own, it may indicate reduced protein intake, absorption issues, or increased protein loss. This finding works together with your protein electrophoresis pattern to give a complete picture of your protein health.
Recommended actions
Ensure adequate daily protein intake from varied sources like lean meats, fish, eggs, and legumes
Stay well-hydrated and maintain a balanced diet with sufficient calories
Consider tracking your protein intake to ensure you're meeting daily needs (typically 0.8g per kg body weight)
Retest in 3-6 months to monitor trends, especially if symptoms persist
Not overhyped or overpriced. Just comprehensive blood testing made simple and for everyone.
