摘　　要：目的探讨尿沉渣法、干化学法、传统镜检在尿液有形成分检测中的应用价值。方法选取2020年1-12月300例行尿液检测的患者,均分别实施尿沉渣法、干化学法、传统镜检,分析阳性检出率,并以传统镜检结果作为对照,分析尿沉渣法、干化学法的检测效果。结果300例尿液检测患者,传统镜检阳性202例、阴性98例,尿干化学法检测阳性182例、阴性118例,尿沉渣法检测阳性164例、阴性136例,传统镜检阳性检出率较尿沉渣法、干化学法更高(P<0.05);以传统镜检结果为标准,尿沉渣法检测的灵敏度为66.34%,特异度为69.39%,阳性预测值为81.71%,阴性预测值为50.00%;尿干化学法检测的灵敏度为72.27%,特异度为63.27%,阳性预测值为80.22%,阴性预测值为52.54%;尿干化学法联合尿沉渣法检测的灵敏度为90.10%,特异度为77.55%,阳性预测值为89.22%,阴性预测值为79.17%。结论在尿液有形成分检测中,联合应用尿干化学法和尿沉渣法能提高尿液中红、白细胞检出率,提高临床检测效果,但传统镜检法不能完全被替代,3种检测技术各具优势及缺陷。Objective To investigate the application value of urinary sediment method,dry chemical method and traditional microscopic examination in the detection of sediment in urine.Methods A total of 300 patients who underwent urine test from January 2020 to December 2020 were selected.Urinary sediment method,dry chemical method and traditional microscopic examination were carried out respectively to analyze the positive detection rate.The results of traditional microscopic examination were used as a control to analyze the detection effect of urinary sediment method and dry chemical method.Results Among 300 patients with urine examination,202 cases were positive and 98 cases were negative by traditional microscopic examination,182 cases were positive and 118 cases were negative by dry chemical method,164 cases were positive and 136 cases were negative by urinary sediment method.The positive rate of traditional microscopic examination was higher than that of urinary sediment method and dry chemical method(P<0.05).Taking the results of traditional microscopic examination as the standard,the sensitivity,specificity,positive predictive value and negative predictive value of urinary sediment method were 66.34%,69.39%,81.71%and 50.00%,respectively.The sensitivity,specificity,positive predictive value and negative predictive value of urine dry chemical method were 72.27%,63.27%,80.22%and 52.54%,respectively.The sensitivity of dry chemical method combined with urinary sediment method was 90.10%,the specificity was 77.55%,the positive predictive value was 89.22%,and the negative predictive value was 79.17%.Conclusion In the detection of urinary sediment,the combined application of urine dry chemistry method and urinary sediment method can improve the detection rate of red and white blood cells in urine and improve the clinical test effect,but the traditional microscopic method can not be completely replaced.The three detection techniques have their own advantages and disadvantages.
