A study was conducted to compare the interest of using Clinitek and leucocytes esterase, blood, nitrites strip Multistix-8 SG (Ames-Bayer Diagnostics) with conventional method (dilution of urine in agar plate) and with automated system (Autobac) as a screening procedure to detect significant bacteriuria. The results are expressed in terms of sensitivity, specificity, predictive value of a negative and positive test. A total of 1303 urine samples were tested of which 730 (56%) were founded negative with Clinitek or conventional urine analysis (Se = 83.6%; VPN = 89.6%). Criteria for urinary tract infection were present for 193 samples (14.8%), the predictive value of a negative test for leucocytes, blood or nitrites (99.6%) justifies the use of Clinitek for economical screening of urine. Overall agreement is higher with the results or Clinitek (in few seconds) than with the Autobac (in 4-5 hours) when compared to the conventional method. The authors propose Clinitek as an effective method for screening and optimised urine analysis for urinary tract infection.
开展了一项研究，以比较使用Clinitek和白细胞酯酶、血液、亚硝酸盐试纸条Multistix - 8 SG（Ames - Bayer诊断公司）与传统方法（在琼脂平板中稀释尿液）以及与自动化系统（Autobac）作为检测显著菌尿的筛查程序的效果。结果以灵敏度、特异性、阴性和阳性检测预测值来表示。总共检测了1303份尿液样本，其中730份（56%）通过Clinitek或传统尿液分析检测为阴性（灵敏度 = 83.6%；阴性预测值 = 89.6%）。193份样本（14.8%）存在尿路感染标准，白细胞、血液或亚硝酸盐阴性检测的预测值（99.6%）证明使用Clinitek进行尿液经济筛查是合理的。与传统方法相比，与Clinitek（在几秒钟内）的结果总体一致性高于与Autobac（在4 - 5小时内）的结果。作者提出Clinitek是一种用于筛查和优化尿路感染尿液分析的有效方法。
