Albumin-corrected calcium

Corrected Calcium Calculator for Albumin

Correct total serum calcium for albumin concentration using SI units, with clinical interpretation for hypo-, normal, and hypercalcaemia ranges.

Corrected calcium calculator

Use this calculator when a total calcium result needs albumin correction. Enter total calcium in mmol/L and albumin in g/L; ClinFuse applies the common SI correction formula and displays the corrected value.

mmol/L

g/L

Corrected calcium

2.38 mmol/L

Typical adult reference interval

Albumin correction

0.10 mmol/L

Positive values add calcium; negative values subtract calcium.


Clinical decision support only. Verify unusual values, follow local guidelines, and interpret calculations alongside the full clinical picture.

Equations used on this page

Corrected calcium (mmol/L) = measured total calcium + 0.02 × (40 - albumin in g/L)

Clinical notes

Albumin correction is an estimate and may be unreliable in critical illness, major acid-base disturbance, and abnormal binding states.

If calcium status is clinically important or symptoms are present, consider ionised calcium where available.

Interpret corrected calcium alongside renal function, phosphate, magnesium, PTH, vitamin D, medication history, and clinical context.
