In a group of 34 adult and child subjects a high correlation (r = 0.988) was found between lean body mass, as determined by potassium-40 counting, and urinary creatinine excretion. The effect of technical errors was reduced by averaging the results of two or three 40K assays on each subject, and by making consecutive 3-day collections of urine. It appears that one can make a reasonable estimate of lean body mass from urinary creatinine excretion.
在一组34名成人和儿童受试者中，通过40钾计数测定的瘦体重与尿肌酐排泄之间发现高度相关性（r = 0.988）。通过对每个受试者的两次或三次40K检测结果进行平均，并连续3天收集尿液，减少了技术误差的影响。似乎可以从尿肌酐排泄量对瘦体重做出合理估计。
