We present a case of multiple myeloma with high values for total calcium. The case discussion focuses on the role of the laboratory in diagnosis and monitoring of multiple myeloma and on the causes of the associated hypercalcemia. We present evidence for calcium binding to the paraprotein as a cause for the "hypercalcemia" in this case and we document a difference in the results for total calcium among various methods when this patient's serum was analyzed.
我们报告一例总钙值升高的多发性骨髓瘤病例。病例讨论聚焦于实验室检查在多发性骨髓瘤诊断和监测中的作用以及相关高钙血症的病因。我们提供证据表明,在该病例中钙与副蛋白结合是导致“高钙血症”的原因,并且记录了分析该患者血清时不同方法测定总钙结果的差异。
