A Method for the Simultaneous Estimation of Total Exchangeable Sodium and Potassium in Man

Abstract
A simple, rapid and accurate method for the simultaneous estimation of total Nae and Ke in man is described. The technique depends on separation by the human body and on the use of two counters. No chemical processing is entailed, nor does it require the expenditure of more counting time than normally would be required for the estimation of either electrolyte alone.
