title: Comparative calcium ion determinations in plasma and whole blood with a new calcium ion analyzer.
abstract: A new Ca2+ analyzer has been used for the determination of Ca2+ in plasma and whole blood from normal subjects and patients with disorders of calcium metabolism. The results were nearly identical: the equation of the regression line was y=1.02x-0.037 and the coefficient of correlation r=0.998. The possibility of using whole blood for measurement with concomitant simplification of the anaerobic sample preparation is an obvious advantage.
