Abstract

Dipstick (reagent strip) and microscopic urine analysis for haematuria was performed prospectively on 1000 consecutive urine samples taken from urological out-patients. Haematuria was present in 185 samples (18.5%) and absent in 687 (68.7%) using both tests; 98 samples (9.8%) had dipstick haematuria that was not confirmed by microscopy and 30 samples (3%) had microscopic haematuria that was missed on dipstick urine analysis. Dipstick urine analysis had a sensitivity of 86.1% and a specificity of 85%. This study confirms that reagent strip testing for haematuria has both false positive and false negative results and indicates that cytoscopy should be considered in all patients with suspected haematuria.

摘要

对从泌尿外科门诊连续采集的1000份尿液样本进行了尿试纸条（试剂条）和显微镜下血尿分析。两项检测结果显示，185份样本（18.5%）存在血尿，687份样本（68.7%）不存在血尿；98份样本（9.8%）尿试纸条检测呈血尿，但显微镜检查未证实，30份样本（3%）显微镜下有血尿，但尿试纸条尿液分析未检测出。尿试纸条尿液分析的灵敏度为86.1%，特异性为85%。本研究证实，血尿的试剂条检测存在假阳性和假阴性结果，并表明所有疑似血尿患者均应考虑进行膀胱镜检查。
