Answer

Chemistry tests include the following [25] :

  • Lactate dehydrogenase (LDH) levels - May be elevated, indicating the extent of Waldenström macroglobulinemia–related tissue involvement

  • Uric acid levels - May be elevated

  • Erythrocyte sedimentation rate (ESR) - May be elevated

  • Renal and hepatic function

  • Total protein levels

  • Albumin-to-globulin ratio

  • Creatinine - Occasionally elevated

  • Electrolytes - Occasionally abnormal; hypercalcemia is noted in approximately 4% of patients; hyponatremia may be present

  • Rheumatoid factor, cryoglobulins, direct antiglobulin test, and cold agglutinin titer results - May be positive
