摘　　要：目的探讨干化学法尿隐血检测的可靠性。方法收集843例泌尿外科住院患者及403名体检人员的尿液标本。分析干化学法尿隐血检测与显微镜检测尿沉渣红细胞(镜检)结果的相符性。结果 843份泌尿外科尿标本中,482份干化学法尿隐血检测阳性,431份(51.1%)镜检阳性;干化学法尿隐血检测阴性与镜检阴性的相符率为98.9%。在843例泌尿外科住院患者和403名体检人员的尿液标本中,干化学法尿隐血检测结果为±、+时,两种方法检测结果相符率远低于干化学法尿隐血检测结果为阴性、++、+++时两种方法检测结果相符率(P<0.05)。两种方法检测279例泌尿系统结石患者阳性相符率最低。结论干化学法尿隐血检测可靠性欠佳,当检测结果异常时,应结合镜检报告结果进行综合判断。Objective To investigate the reliability of dry-chemistry method in detecting urine occult blood（BLD）. Methods Collected urines from 843 urological patients and 403 physical examination people who met the conditions. BLD in samples were de- tected with dry-chemistry method, erythrocytes were observed by microscope. Analyzed the differences between the two results. Re- sults 482 samples （57.2%） were tested positive in BLD,while 431 samples（51, l~）were positive in microscope detection in 843 samples from urological patients. In BLD negative samples, 98.9 % were also observed negative in microscope detection. In 843 urine specimens from urologic patients and 403 urine specimens from physical examination people, the match rate of the two methods when the results of BLO were ~＋ or ＋ was much lower than that when the results of BLO were negative, ＋ ＋, ＋ ＋ -＋- （P^0.05）. In 279 specimens from patient with urinary calculi, the match rate of positive results between the two methods was the lowest one. Conclusion The reliability of dry-chemistry method in detecting urine occult blood is not satisfactory. When abnormal test result occurs,microscope detection should be combined to make a comprehensive judgment.
