To evaluate the diagnostic significance of the Sudan III staining for the fecal fat, the quantitative relationship between the number of fecal fat droplets examined microscopically and the amount of the fecal fat determined chemically was examined. In 43 out of 60 cases, the results of the chemical determination and the microscopic examination were in agreement and the accuracy was 72 percent. On the other hand, the false positive cases totaled 9 out of the 24 cases (37 percent) and 8 out of 9 false positive cases were diagnosed as showing a slight increase. In contrast, the false negative cases were only 2 out of 36 cases (6 percent). In addition, the comparative study of the various procedures of the Sudan III staining indicated the importance of the processing with acid and heating even in cases of steatorrhea caused by pancreatic insufficiency.
为评估苏丹III染色对粪便脂肪的诊断意义，研究了显微镜下检查的粪便脂肪滴数量与化学测定的粪便脂肪量之间的定量关系。60例中有43例化学测定结果与显微镜检查结果一致，准确率为72%。另一方面，24例中有9例假阳性病例（37%），9例假阳性病例中有8例被诊断为略有增加。相比之下，36例中假阴性病例仅2例（6%）。此外，苏丹III染色各种方法的对比研究表明，即使在胰腺功能不全引起的脂肪泻病例中，酸处理和加热处理也很重要。
