Hypocalcemia Laboratory Evaluation
Serum levels of PTH, phosphorus, 25-hydroxyvitamin D, and 1,25-dihydroxyvitamin D can help differentiate between disorders causing hypocalcemia:
- Hypoparathyroidism
- Calcium-sensing receptor activating mutation
- Parathyroid hormone resistance (pseudohypoparathyroidism)
- Vitamin D deficiency
- Chronic kidney disease
