三种方法检测尿液红细胞白细胞结果研究∗

摘要

Objective:To Observe urinary sediment analyzer 、microscopic examination of urinary sedi-ment dry chemical test the sensitivity and specificity of urine red blood cell, white cell, and analyze the in-fluence the factors of the final testing results. Method:880 cases of fresh urine samples were randomly se-lected , they were respectively used urine sediment analyzer, urine microscopic examination, dry chemistry detection WBC and RBC in urine , microscopic examination of urinary sediment was as the gold standard, sediment analyzer and urine dry chemistry method to detect the sensitivity and specificity of WBC and RBC were observed. Result:The urine sediment analyzer、microscopic examination of urinary sediment detection of urine 、dry chemical method in the detection of positive rate of RBC were respectively 18.98%,12.39%, 15. 68%;The urine sediment analyzer、 microscopic examination of urinary sediment detection of urine、dry chemical method in the detection of positive rate of WBC were respectively 22.16%,18.75%,26.25% . dry chemical method in the detection of sensitivity of RBC was 75.23%,specificity was 92.74%;The urine sedi-ment analyzer in the detection of sensitivity of RBC was 88.99%,specificity was 90.92%. Dry chemical meth-od in the detection of sensitivity of WBC was 93.33%,specificity was 89.23%;The urine sediment analyzer in the detection of sensitivity of WBC was 98.18%,specificity was 95.38% . Conclusion:Urinary sediment an-alyzer and dry chemical method are with respect to the microscopic examination of urinary sediment, it can quickly get the test results , But its overall accuracy test is still insufficient, need to be combined in clinical application of the three methods, it can improve the accuracy of urine testing .%目的：：观察尿沉渣分析仪、尿沉渣镜检、干化学法检验尿液红细胞、白细胞的灵敏度以及特异度,并分析影响最终检测结果的因素。方法：随机选取新鲜尿液标本880例,分别用尿沉渣分析仪、尿沉渣镜检、干化学法检测尿液中的WBC和RBC,以尿沉渣镜检法为金标准,观察沉渣分析仪以及干化学法检测尿液中的WBC和RBC的灵敏度和特异度。结果：尿沉渣分析仪、尿沉渣镜检、干化学法检测尿液中的RBC的阳性率分别为18.98%、12.39%、15.68%；尿沉渣分析仪、尿沉渣镜检、干化学法检测尿液中的WBC的阳性率分别为22.16%、18.75%、26.25%。干化学法检测尿液中RBC的灵敏度为75.23%,特异度为92.74%；尿沉渣分析仪检测尿液中的RBC的灵敏度为88.99%,特异度为90.92%。干化学法检测尿液中WBC的灵敏度为93.33%,特异度为89.23%；尿沉渣分析仪检测尿液中的WBC的灵敏度为98.18%,特异度为95.38%。结论：尿沉渣分析仪与干化学法相对于尿沉渣镜检而言,能够快速地得出检验结果,但是其检验的整体准确性仍然不足,在临床中需将三种方法联合应用,才能提高尿液检测的准确性。
