Corrected Calcium Calculator
Calculates corrected calcium levels for patients with hypoalbuminemia using the formula: Corrected Calcium (mg/dL) = Measured Total Calcium (mg/dL) + 0.8 * (4 - Albumin (g/dL)).

How to use the Corrected Calcium Calculator
- Enter Measured Total Calcium (in mg/dL) into the first field. Example:
8.5. - Enter Albumin (in g/dL) into the second field. Example:
3.0. - Click the "Calculate Corrected Calcium" button.
- The result displays as Corrected Calcium in mg/dL, using the formula: Corrected Ca = Measured Ca + 0.8 × (4 - Albumin).
- If you see an error, ensure both values are non-negative numbers (decimals allowed).
Note: All values must be in the units shown (mg/dL for calcium, g/dL for albumin). No unit conversion is needed.

Frequently Asked Questions
Corrected calcium adjusts total calcium levels for albumin concentration, providing a more accurate assessment of calcium status in patients with abnormal albumin levels.
It is commonly used in patients with hypoalbuminemia (low albumin) to estimate free calcium levels, as total calcium may be falsely low.
This calculator uses mg/dL for both calcium and albumin. Ensure your lab values are in these units.
