目的：探讨鉴别肾小球性与非肾小球性血尿的检验方法。方法：用血细胞计数仪检测尿中红细胞平均体积（ＭＣＶ）并结合显微镜红细胞形态观察。结果：肾小球性血尿：尿ＭＣＶ为６２．２±５．２ｆｌ，变形红细胞百分率４６．７±１２．０％；非肾小球性血尿：尿ＭＣＶ为８９．４±５．８ｆｌ，变形细胞百分率１０．０±５．０％，两者存在显著性差异（Ｐ＜０．０１）。尿ＭＣＶ结合尿红细胞形态观察，对肾小球性血尿诊断符合率为９５％（３８／４０），非肾小球性血尿诊断符合率为９８％（４８／４９）。结论：用血细胞计数仪测定尿ＭＣＶ结合显微镜观察尿ＲＢＣ形态，对单纯性血尿的鉴别诊断颇有价值
Objective: To investigate the identification of glomerular and non-glomerular hematuria test methods. Methods: The average volume of erythrocytes in the urine (MCV) was detected with a hemocytometer and observed with the morphology of the erythrocytes. Results: Glomerular hematuria: the MCV of urine was 62.2 ± 5.2fl, the percentage of deformable erythrocytes was 46.7 ± 12.0%; the non-glomerular hematuria: urine MCV was 89.4 ± 5.8fl The cell percentage was 10.0 ± 5.0%, there was a significant difference between the two (P <0.01). Urine MCV combined with urinary erythrocyte morphology, the diagnostic accuracy of glomerular hematuria was 95% (38/40), non-glomerular hematuria was 98% (48/49). Conclusion: The determination of urinary MCV with microscope with a hemocytometer in urine RBC morphology, the differential diagnosis of simple hematuria is valuable
