Interference from Heparin in Commercial Heparinised Tubes in the Measurement of Plasma Sodium by Ion Selective Electrode: A Note of Caution

Sodium and potassium concentrations were measured in both whole blood and plasma from a series of 21 patient samples using a Corning 902 ISE. The difference between whole blood and plasma values for both analyses was not significant. The correlation coefficient and slope for sodium was 0·988 and 0·966 and for potassium was 0·998 and 1·04. A series of serum specimens (n=88), and a different series of plasma specimens, were each analysed by ISE and FE.
