Regression equations of total red cell volume on body weight, body surface area, lean body mass, etc., are provided for a series of 79 normal male volunteer subjects. The regression of total red cell volume on a combination of height and weight provided the smallest standard error of the estimate and the largest correlation coefficient. The coefficient of variation was 1.6 percent between the first and second red cell volume determination in 31 of these subjects. The popular expression of total red cell volume in ml per kg remains unsatisfactory. It is recommended that a comparison be made between a measured total red cell volume and a predicted normal range derived from a regression using body surface area as the independent variable. A simplified graph is provided which clearly delineates normal from abnormal and should prove adequate for most clinical situations.
为79名正常男性志愿者提供了红细胞总体积与体重、体表面积、去脂体重等的回归方程。红细胞总体积与身高和体重组合的回归给出了最小的估计标准误差和最大的相关系数。在这些受试者中的31人身上，第一次和第二次红细胞体积测定之间的变异系数为1.6%。每千克毫升数这种常用的红细胞总体积表达方式仍不尽人意。建议将测得的红细胞总体积与以体表面积为自变量通过回归得出的预测正常范围进行比较。提供了一张简化图表，该图表能清晰区分正常与异常情况，并且应该足以应对大多数临床情况。
