This corrected calcium reference table shows the corrected calcium for a range of measured calcium values, assuming a serum albumin of 2.5 g/dL. Every figure is computed with the same engine that powers our Corrected Calcium Calculator, so the numbers are exact.
| Measured calcium | Corrected calcium |
|---|---|
| 2 mg/dL | 3.20 |
| 4 mg/dL | 5.20 |
| 6 mg/dL | 7.20 |
| 8 mg/dL | 9.20 |
| 12 mg/dL | 13.20 |
| 16 mg/dL | 17.20 |
| 24 mg/dL | 25.20 |
| 40 mg/dL | 41.20 |
| 56 mg/dL | 57.20 |
| 80 mg/dL | 81.20 |
How to use this table
Find the row closest to your measured calcium and read across to the corrected calcium. For a value between two rows, the real figure sits between them — or enter your exact numbers in the Corrected Calcium Calculator for a precise answer.
Need a value that is not in the table? — the Corrected Calcium Calculator does it instantly, for free, with the formula and a worked example built in.
