用日本产的ＣＩＳ－Ｆ８２０血细胞计数仪对４６份血尿标本进行检测，结果２６份肾小球性血尿的红细胞平均细胞体积（ＭＣＶ）为６５８±５５８ｆｌ，２０份非肾小球血尿的ＭＣＶ为９４５±６１３ｆｌ，两组结果差异有高度显著性（Ｐ＜００１），实验证实，以尿ＭＣＶ区分肾小球性与非肾小球性肾炎血尿的准确性为１００％，敏感性９１７％，特异性９４７％，肾小球肾炎结果的判断价值为９５６％，非肾小球肾炎结果的判断价值为９０％，可初步判断血尿来源，因此，本实验是一种简便、快速、客观及无创伤性的鉴别血尿来源的筛选检查。
46 Japanese hematuria samples were detected with a Japanese-made CIS-F820 hemocytometer. The results showed that the mean cell volume (MCV) of 26 glomerular hematuria was 658 ± 558fl, and that of 20 non-glomerular hematuria The MCV was 94.5 ± 6.13fl, the difference between the two groups was highly significant (P <0 01), the experiment confirmed that the accuracy of urinary MCV distinguish glomerular and non-glomerular nephritis hematuria as 100%, 91.7% sensitivity, 94.7% specificity, glomerular nephritis results to determine the value of 95.6%, non-glomerulonephritis results to determine the value of 90%, you can initially determine the source of hematuria, Therefore, this experiment is a simple, rapid, objective and non-invasive identification of the source of hematuria screening test.
