Two machines, the Clinitek 200 and the Rapimat II/T, were evaluated for their ability to screen urine samples for significant bacteriuria and other elements indicative of urinary tract pathology. The automated screening procedures were compared with a conventional approach of microscopy and quantitative culture for 1020 urine specimens obtained from patients in a 700 bed general hospital. When compared with the bacterial culture method both machines gave identical results with a negative predictive value of 0.99, while when compared with microscopy alone the Clinitek 200 and Rapimat II/T gave negative predictive values of 0.92 and 0.87, respectively. It is concluded that both machines would provide cost effective screening of urine specimens.
对Clinitek 200和Rapimat II/T这两台机器进行了评估，以检测其筛查尿样中显著菌尿及其他泌尿系统病理指标的能力。针对一家拥有700张床位的综合医院中1020份患者尿样，将自动筛查程序与传统的显微镜检查和定量培养方法进行了比较。与细菌培养方法相比，两台机器得出的结果相同，阴性预测值为0.99；而仅与显微镜检查相比时，Clinitek 200和Rapimat II/T的阴性预测值分别为0.92和0.87。结论是两台机器都能提供具有成本效益的尿样筛查。
