The other crazy number was the most severe hypercalcemia I have ever seen. The calcium was 18 mg/dL with an albumin of 3.7 g/dL. The patient is a kidney transplant recipient who was recently seen in the outpatient clinic with hypocalcemia. His calcium was 6.5 and his calcitriol was increased from 0.5 mcg to 1 mcg twice daily. He was also continued on his calcium carbonate.
The other pertinent calcium labs:
- PTH: 3.2 pg/mL
- Vit D 1,25 dihydroxy: 36 pg/mL
- SPEP/UPEP: unremarkable
- PTHrp: pending
