Question 1

What is a Corrected Calcium?

Accepted Answer

Low albumin falsely lowers measured serum calcium. Corrected calcium adjusts for this to reveal the true physiologically active level, essential for correct clinical interpretation.

Question 2

How does the Corrected Calcium work?

Accepted Answer

Corrected Ca = Measured Ca + 0.8 × (4 − Albumin g/dL) Then: Normal albumin = 4 g/dL Then: Normal corrected calcium = 8.5–10.5 mg/dL Then: Each 1 g/dL drop in albumin lowers measured Ca ~0.8 mg/dL.

Question 3

Can you give an example of how to use the Corrected Calcium?

Accepted Answer

Example: Input Ca 7.6, Albumin 2.2 g/dL gives a result of Corrected Ca = 7.6 + 0.8×1.8 = 9.04 mg/dL (actually normal).

Question 4
