Inputs
Normal total Ca: 8.5–10.5 mg/dL; hypocalcemia: <8.5; hypercalcemia: >10.5 mg/dL
Normal albumin: 3.5–5.0 g/dL; correction: +0.8 mg/dL Ca per 1 g/dL drop in albumin
Results
Corrected Calcium
9mg/dL
How to Use This Calculator
- Enter measured serum calcium (mg/dL) and serum albumin (g/dL).
- Review Corrected Calcium, Correction Amount, and Classification (hypocalcemia, normal, or hypercalcemia).
- Always correct calcium for albumin before interpreting total calcium in hypoalbuminemic patients.
