WebTypically, ionized calcium is measured on a blood gas analyzer using an ion selective electrode with whole blood specimens. Free calcium measurement does have quite stringent collection and handling requirements, which is often cited as the reason it is not used universally. WebTo overcome this, various nomograms and formulae have been developed to estimate ionized calcium by correcting total calcium for total protein, albumin, globulins, and pH. The most widely used of these is the Payne et al. formula: Adjusted calcium (mmol/L) = Total calcium (mmol/L) + 0.02 [40 – serum albumin (g/L)].
