The distribution of alcohol in the blood is determined by the water content of serum and whole blood. In order to verify the conversion factor qu for the establishment of the "blood alcohol concentration" from the alcohol content of the serum, the serum protein content, the hematocrit and the water content of the serum and whole blood were determined in 246 persons suffering from diseases in which disturbances of the water content of the blood could be expected. It was shown that the conversion factor of 1,20 used in the routine practice of the alcohol laboratory is too large. Calculation of blood alcohol concentration from the serum alcohol using the conversion factor of 1,20 leads to a levelling of differences of about 10%.
血液中酒精的分布取决于血清和全血的含水量。为了验证从血清酒精含量确定“血液酒精浓度”的转换系数qu，对246名患有预期会出现血液含水量紊乱疾病的患者测定了血清蛋白含量、血细胞比容以及血清和全血的含水量。结果表明，酒精实验室常规操作中使用的1.20的转换系数过大。使用1.20的转换系数从血清酒精计算血液酒精浓度会导致约10%的差异被抹平。
