尿液潜血试验与镜检红细胞结果的对比观察

目的观察比较镜检尿红细胞和尿潜血经过尿液分析仪检测后的结果。方法选取2009年7月至2009年7月我院收治的内科住院患者256例,作为研究对象。采集患者新鲜的晨尿,在第一时间用尿液分析仪检测血的阴阳性。在显微镜下观察是否有红细胞并数出其个数。根据观察结果对比尿液潜血试验与镜检红细胞的测量准确度。结果用镜检尿红细胞法检测出患者潜血呈阴性的患者数116,呈阳性的患者数140。用尿液分析仪检测出患者潜血呈阴性的患者数102,呈阳性的患者数154。两组结果经χ2检验后得出两组结过有明显差异,具有统计学意义。患者经尿液分析仪判断出阴性后镜检有红细胞的患者数5名,无红细胞的患者数为97名。判断出阳性后镜检有红细胞的患者数135名,无红细胞的患者数为15名。结果经χ2检验后得出两组结过有明显差异,具有统计学意义。结论尿液潜血试验与镜检红细胞联合起来会增加测量准确度。

Comparison of the Results Observed Urine Occult Blood Test and Microscopic Examination of Red Blood Cells

Objectives Compare the microscopic examination of urinary red blood cells and urinary occult blood detected through urine analysis results. Methods 256 cases from July 2009 to July 2009, the hospital medical inpatients, as the object of study. Collection in patients with flesh morning urine, and urine analysis detected by blood, yin and yang, the first time. Whether there are red blood cells under a microscope and count their number. Comparison based on the observed results of the measurement accuracy of the urine occult blood test and microscopic examination of red blood cells. Results Microscopic examination of urinary red blood cells detected number of 116 patients with occult blood-negative patients, showing the number of 140 patients with positive urine analysis detected a number of 102 patients with occult blood-negative patients, the number of 154 positive patients two sets of resultsdrawn by the Z2 test to two groups Results were significantly different, with statistical significance. Patients after a negative urine analyzer to determine the microscopic examination of red blood cells in patients 5, the number of red blood cells of patients with 97. Determine a positive after microscopic examination of 135 patients with red blood cells, red blood cells of patients 15. Results obtained by the Z： test after two groups Results were significantly different, with statistical significance. Conclusions Urine occult blood test and microscopic examination of red blood cells together to increase the measurement accuracy.
