Body surface area (BSA) is probably the most used tool for indexing physiological functions. The most relevant past and present measuring methods have been examined, and an analysis of selected methods used to measure and to estimate was performed. The evaluation of methods demonstrates a relationship between past and present measuring methods, but also highlights the doubtfulness of their suitability due to the criteria used to select the population for measurements and to estimate BSA by formulae, due to the weight variance according to the same height and the lack of a numeric estimate of the body shape. The use of BSA formulae generated from a population with anthropometric measures different from those of a population where the formulae are applied, and the change in today's BSA towards 1.73 m(2) can induce risks by incorrectly estimating GFR and in planning dialysis prescriptions.
体表面积（BSA）可能是用于索引生理功能最常用的工具。已经检查了最相关的过去和现在的测量方法，并对用于测量和估计的选定方法进行了分析。方法评估表明过去和现在的测量方法之间存在关系，但也突出了由于用于选择测量和通过公式估计 BSA 的人群的标准、由于根据相同身高的体重差异以及缺乏身体形状的数值估计，它们的适用性值得怀疑。使用与应用公式的人群的人体测量指标不同的人群生成的 BSA 公式，以及当今 BSA 向 1.73 m(2)的变化，可能会通过不正确估计 GFR 和规划透析处方而带来风险。
