Normalized quantitative equations were derived to permit the calculation of intra‐ and extra‐erythrocyte ionic contents of human blood following the in vitro application of contrast media. These formulae allow the ionic contents to be computed, which should be present in plasma and erythrocytes if, after contrast medium administration, no ionic shifts occur other than electrolyte unbalance as induced by changes in water content. The equations are also applicable when other aqueous solutions are added to human blood.
