评价了黄色IRIS 450型尿液分析工作站（国际远程成像系统）检测392份标本中可预测尿路感染（UTI）的尿液异常的能力。采集和检测之间允许的时间限制为2小时。产生的标本中菌落形成单位（CFU/mL）≥ 104且存在白色血细胞（WBC）的患者被认为患有UTI。当这些标本中不存在WBC时，以及当存在WBC但分离出的CFU/mL低于104时，对病历进行审查，以确定UTI的临床证据。显示出最佳灵敏度和特异性的因素组合是每个HPF 2个WBC或更多和/或每个HPF 2个红细胞或更多（分别为92.8%和60.1%）。
The Yellow IRIS Model 450 Urinalysis Workstation (International Remote Imaging Systems) was evaluated for its ability to detect abnormalities in urine that could predict urinary tract infection (UTI) in 392 specimens. The time allowed between collection and testing was limited to 2 hours. Patients yielding specimens containing 104 or more colony forming units per milliliter (CFU/mL) with white blood cells (WBCs) present were considered to have UTI. Medical records were reviewed for clinical evidence of UTI when WBCs were absent in these specimens, and when WBCs were present, but less than 104 CFU/mL were isolated. The combination of factors that displayed optimum sensitivity and specificity was 2 WBCs or greater per HPF and/or 2 red blood cells or greater per HPF (92.8% and 60.1%, respectively).
