Corrected Calcium Calculator
Calculate corrected calcium levels adjusted for albumin to accurately assess calcium status in hypoalbuminemia.
Lab Values
g/dL
Normal albumin level (usually 4.0 g/dL)
Corrected Calcium

Correction Effect
Albumin correction increased calcium by 0.8 mg/dL
Corrected calcium within normal range
About Calcium Correction
Formula
Corrected Ca = Measured Ca + 0.8 × (4.0 - Albumin)
For every 1 g/dL decrease in albumin below 4.0, add 0.8 mg/dL to measured calcium.
Normal Ranges
- Total Calcium: 8.5-10.5 mg/dL
- Ionized Calcium: 4.5-5.3 mg/dL
- Albumin: 3.5-5.0 g/dL
