血液分析仪测定尿红细胞鉴别血尿来源临床价值探讨

The Assessment of the Clinical Significance of the Source of RBC in Patients with Hematuria by Hematoanalyser

本文使用CD-1500血液分析仪检测了44例肾小球肾炎、39例非小球病变尿中红细胞体积分布曲线、MCV及RDW等参数,观察了其在鉴别血尿来源的临床价值。结果表明,肾小球肾炎与非球性病变红细胞分布曲线特点不同,峰值差异很大。两者MCV均值分别为60.26±15.57fl,86.56±15.9fl,如以≤72fl为鉴别小球性肾炎的标准,敏感性为84.1％,特异性84.6％,约登指数为0.6g,显示观察曲线变化及MCV值对鉴别血尿来源有重要意义。但RDW用于鉴别诊断临床价值较差。

Red blood cell volume distribution curve (RDG), mean corpuscular volume (MCV) and red blood cell volume distribution width (RDW) in urine were measured in 44 cases with glomeruloneph ritis and 39 cases with non-glomerulonephritis and their clinical significance on differentiating hematuria were observed. The results showed that there were obvious difference between glomerulonephritis and non-glomerulonephritis about the characteristic of the RBC. The MCV (average) were 60.26±12.57 f1 and 80.56±15.9f1 respectively. if 72f1 was used as a standard to differentiate glomerulonephritis and non-glomerulonephritis. The sensitivity and specificity of differentiating hematuria were 84.1％, 84.0％ respectively. There was less clinical significance with RDW in differentiating glomerulonephritis and non-glomerulophritis.
