The whole body potassium content of a group of carefully screened, healthy, elderly subjects, mean age 73.5 years, has been accurately measured. The mean content was found to be approximately 10% lower than expected though there was a considerable range of individual values. Some of the interindividual variability could be reduced by taking into account body weight, height and in particular fat-free mass. The ratio of whole body potassium to fat-free mass (52.4 +/- 6.7 mmol/kg) was exceptionally low in this healthy group and showed no sex difference.
对一组经过仔细筛选的、健康的老年受试者（平均年龄73.5岁）的全身钾含量进行了精确测量。尽管个体值存在相当大的范围，但发现平均含量比预期低约10%。通过考虑体重、身高，尤其是去脂体重，可以减少个体间的一些变异性。在这个健康组中，全身钾与去脂体重的比率（52.4±6.7 mmol/kg）异常低，且无性别差异。
