A Clinically Useful Method for Determining Erythrocyte Sodium and Potassium

Harold J. Helbock 1 and David M. Brown 1

1 Departments of Pediatrics and Laboratory Medicine, University of Minnesota College of Medicine, Minneapolis, Minn. 55455.

A method is presented for determining erythrocyte sodium and potassium concentration. Heparinized whole blood is separated into cellular and plasma fractions in large-bore capillary tubes. An aliquot of the erythrocyte fraction is then pipetted directly into lithium chloride diluent and the electrolytes determined flame photometrically. Plasma trapping is measured with 14C-inulin and corrections calculated for trapped sodium and potassium. This technique is rapid, simple, and can be performed as a routine procedure by most clinical laboratories.


Key Words: flame photometry • 14C-inulin in measurement of plasma trapped in centrifuged cells • normal values • interindividual 30-day variation
