Health Measurements
Corrected Calcium Calculator
Apply the conventional simplified albumin adjustment to total calcium while keeping the measured value visible.
Formula
Adjusted calcium (mg/dL) = measured calcium + 0.8*(4.0-albumin g/dL).
About the Corrected Calcium Calculator
Apply the conventional simplified albumin adjustment to total calcium while keeping the measured value visible.
How the Corrected Calcium Calculator Works
The conventional coefficient adjusts total calcium toward an albumin reference of 4.0 g/dL; both measured and adjusted results are reported.
Formula
Adjusted calcium (mg/dL) = measured calcium + 0.8*(4.0-albumin g/dL).
The calculation runs in your browser. Values are validated for required ranges, compatible units, and method-specific restrictions before results are displayed.
Required Inputs
- Measured total calcium (required) - enter in mg/dL.
- Serum albumin (required) - enter in g/dL.
Results Reported
The result panel reports the final answer and the intermediate quantities needed to check the calculation:
- Measured total calcium (mg/dL)
- Albumin adjustment (mg/dL)
- Conventionally adjusted calcium (mg/dL)

Accuracy and Limitations
Albumin-adjusted calcium can misclassify calcium status and does not replace measured ionized calcium or laboratory-specific guidance, especially in critical illness or kidney disease.
Keep units consistent, use measurements that represent the actual situation, retain full precision during the calculation, and round only the final answer. Professional decisions may require current official rules, field measurements, laboratory methods, or specialist review.
