Separated erythrocytes are washed repeatedly with iso-osmolar magnesium chloride solution, lysed by adding saponin, and sodium potassium measured in the diluted hemolysate by flame photometry. The coefficient of variation for the method was less than 4%. Reference intervals determined for a healthy population and hospitalized (elective surgery) patients without electrolyte disorders were 4.6-7.8 mmol/liter for erythrocyte sodium concentration and 94-110 mmol/liter for erythrocyte potassium concentration (2.5-97.5 percentiles).
分离出的红细胞用等渗氯化镁溶液反复洗涤，加入皂素使其裂解，然后通过火焰光度法测定稀释后的溶血产物中的钠和钾。该方法的变异系数小于4%。针对健康人群和无电解质紊乱的住院（择期手术）患者确定的参考区间为：红细胞钠浓度为4.6 - 7.8毫摩尔/升，红细胞钾浓度为94 - 110毫摩尔/升（第2.5至97.5百分位数）。
