Can you remember what formula you need to use to calculate corrected calcium levels?

Formula is “Corrected” Ca (mmol/L) = Ca “measured” (mmol/L) +/- 0.02 (40 – albumin (g/L))

A patient’s calcium is 2.55mmol/l and albumin is 35g/l. What is the patient’s corrected calcium level?

Corrected calcium is: 2.55 + 0.02 (40 – 35) = 2.65mmol/l

What does this level indicate?

This indicates that hypercalcaemia is present.
