## Quick Answer

Calculate corrected calcium levels for patients with abnormal albumin concentrations. Enter total calcium, serum albumin, and reference values to estimate the physiologically active calcium level.

## Definition

A corrected calcium calculator is a clinical medical utility used to estimate a patient's true physiological calcium level when serum albumin concentrations are abnormal. Because a large fraction of serum calcium is bound to albumin, hypoalbuminemia or hyperalbuminemia can distort total calcium test results. The calculator applies the standard correction formula, which adjusts the total calcium concentration upward or downward based on the difference between the patient's albumin level and a normal reference baseline. Healthcare professionals use this tool to evaluate calcium balance and guide treatment.

## How to Use

1. **Enter total calcium** — Type the patient's total serum calcium concentration from the lab results.
2. **Enter serum albumin** — Input the measured albumin concentration in grams per deciliter.
3. **Select measurement units** — Choose the appropriate units of measurement for calcium and albumin.
4. **Read corrected level** — View the estimated corrected calcium level and compare it against standard reference ranges.
