CBC revealed the following values: hemoglobin, 10.5 g/dL; hematocrit, 31.8%; mean corpuscular volume, 87.6 fL; WBC count, 6,460/μL (neutrophils, 70%; lymphocytes, 20%; monocytes, 9%; eosinophils, 1%); and platelet count, 185,000/μL. Blood chemistry tests revealed the following values: total protein, 90 g/L; serum albumin, 20.8 g/L; corrected serum calcium, 9.3 mg/dL (normal range, 8.5-10.1 mg/dL); serum phosphorus, 3.6 mg/dL (normal range, 2.5-4.9 mg/dL); serum lactate dehydrogenase (LDH), 556 U/L (normal range, 100-190 U/L); BUN, 23 mg/dL; serum creatinine, 1.89 mg/dL; and serum sodium, 129 mmol/L. Serum prostatic-specific antigen level was 4.2 ng/mL (normal range, 0-4 ng/mL), and serum CA-125 level was 80.3 U/mL (normal range, 0-35 U/mL). A heat precipitation test for Bence-Jones proteinuria (BJP) was negative. Other laboratory tests were within normal limits. Urine electrophoresis and serum protein electrophoresis (SPEP) were not done.
