摘要
目的研究尿液分析试纸在腹水感染中的诊断价值。方法选择不同病因形成的腹水标本33例,应用尿液分析试纸对腹水标本进行白细胞检测,同时与手工计数法作比较,并作统计学分析。结果尿试纸检验结果阳性率为54.5%,传统方法结果阳性率为57.6%。两种方法阳性率比较,差异无统计学意义(P>0.05)。应用尿液分析试纸结果的敏感性78.95%,特异性78.57%,阳性预测值83.33%,阴性预测值73.33%,尿液分析试纸对诊断腹水感染的敏感性及特异性均较高。计算kappa值为0.57,尿液分析试纸与手工计数法两种方法一致性较好。结论尿液分析试纸检测法具有快速、操作简单、结果比较可靠等优势,在临床上应用于腹水感染的初步筛检有一定的可行性。
Objective To study the diagnostic value of urine analysis test strips in infection of ascites. Methods Thirty three ascites samples were collected from patients due to different causes, urinalysis test strips were used to detect white blood cells in ascites specimens and their results were compared with those of manual counting method. Results The positive rate of urine dipstick test was 54.5% and that of traditional method was 57.6%, the difference was not statistically significant （ P 〉 0.05 ）. For the results of urine dipstick test, the sensitivity was 78. 95%, the specificity was 78.57%, positive predictive value was 83.33% and its negative predictive value was 73.33%. For the diagnosis of in- fections of ascites, urine dipstick test had high sensitivity and specificity. The kappa value was 0.57, urine dipstick test and manual counting method were in good coincidence. Compared with manual counting method for diagnosis of infection of ascites, urine analysis dipstick assay was in good coincidence with manual counting method. Conclusion The application of urinalysis dipstick test is a rapid, simple and reliable method, and it has some value in clinical application for preliminary screening infection of ascites.
