Over the following weeks, laboratory testing demonstrated continued hypercalcemia above 12 mg/dL (> 3.07 mmol/L) with depressed parathyroid hormone 8 pg/mL (8 ng/L) (RR 15-65 pg/mL; 15-65 ng/L), mildly elevated PTHrP 24 pg/mL (2.4 pmol/L) (RR 11-20 pg/mL; < 2.0 pmol/L), and 1,25-dihydroxyvitamin D elevated above the upper reference limit of detection of 200 pg/mL (> 499 pmol/L) (RR 18-64 pg/mL; 24-45 pmol/L) in the setting of normal levels of 25-hydroxyvitamin D (25 ng/mL; 62.4 nmol/L) (RR > 20 ng/mL; 9-200 nmol/L) and albumin (4.7 g/dL (47.0 g/L) (RR 3.2-4.7 g/dL; 32-47 g/L). This evidence concerns the gene PTHLH and Hypercalcemia.
