At admission, the patient's metabolic panel revealed the following findings (reference ranges appear in parentheses): blood urea nitrogen, 36 mg/dL (5-20 mg/dL); creatinine, 1.00 mg/dL (0.60-1.00 mg/dL); serum glucose, 250 mg/dL (65-100 mg/dL); chloride, 109 mEq/L (98-107 mEq/L); magnesium, 1.6 mEq/L (1.8-2.4 mEq/L); total protein, 6.0 g/dL (6.4-8.2 g/dL); albumin,1.6 g/dL (3.4-5.0 g/dL); lactate dehydrogenase, 664 U/L (81-234 U/L); alkaline phosphatase, 149 U/L (50-136 U/L); alanine aminotransferase, 83 U/L (12-78 U/L); and aspartate aminotransferase, 54 U/L (10-37 U/L). Hemoglobin A1c was 8.8% (4.5%-6.2%).
Thyroid-stimulating hormone level was 0.133 mIU/L (0.510-6.270 mIU/L), total triiodothyronine uptake was 47.53% (22.5%-37.0%), and total thyroxine was 5.20 ng/dL (4.50-10.90 ng/dL).
White blood cell count was 3.9 × 103 μL (4.5 × 103 μL to 11.0 × 103 μL); hemoglobin, 10.5 g/dL (12.0-16.0 g/dL); hematocrit, 31.3% (37.0%-47.0%); and platelet count, 28 × 103 μL (150 × 103 μL to 400 × 103 μL). Differential blood cell count revealed 87.1% neutrophils and 6.2% lymphocytes. Manual differential count showed 87 segmented neutrophils (33-66) and 2 bands (0-10). Absolute neutrophil count was 3855 cells/μL. Total serum iron level was 144 μg/dL (50-175 μg/dL), with a ferritin level of 246 ng/mL (10-291 ng/mL).
Findings from the patient's urinalysis and blood cultures were unremarkable.
