  A 50-year-old African american woman presents to your clinic with increased thirst and increased urination. You review her old records and it appears like she had a Chest X-ray in the ER last year that showed bilateral hilar lymphadenopathy. She was advised follow-up but she did not comply at that time. Upon examination, you discover some subcutaneous skin nodules and biopsy of one of these comes back positive for non-caseating granulomas.

Laboratory studies from a week ago show:

Hemoglobin 15.2gm%

Calcium : 11.6mg%

Creatinine : 1.0mg%

Which of the following investigations may explain the underlying mechanism of her Hypercalcemia?

A. Biopsy of Hilar Lymph Node

B. 25 Hydroxy Vitamin D Level

C. PTH related peptides

D. 1,25 di-hydroxy Vitamin D level

E. Serum Protein Electrophoresis

  Hypercalcemia should be investigated first with PTH and since there is no option for that next best available answer is D.
