Although sodium and potassium have been the most commonly assayed analytes by clinical chemists for many years there have been fewer analytical principles used routinely than for most other analytes. The introduction of the direct-reading ion-selective electrode has led to a re-examination of the basic concepts of the methods involved, and this in turn to a reassessment of the interpretation of the measurement of sodium in certain clinical situations. As a result there is a case for all clinical chemistry laboratories having access to a direct-reading ion-selective electrode for sodium estimation.
尽管多年来钠和钾一直是临床化学家最常检测的分析物，但与大多数其他分析物相比，常规使用的分析原理较少。直读式离子选择电极的引入促使人们重新审视相关方法的基本概念，进而重新评估在某些临床情况下钠测量结果的解读。因此，所有临床化学实验室都应有直读式离子选择电极用于钠的测定。
