摘要 目的:比较2种大便隐血常规测定方法的优缺点。方法:选择100例正常人的粪便作为常规粪便标本,选择25例上消化道出血患者的粪便以及25例下消化道肿瘤患者的粪便作为诊断标本,分别用单克隆抗体法以及改良的匹拉米洞法进行大便隐血常规测定。结果:单克隆抗体法的血红蛋白检测结果只受人体血红蛋白影响,改良的匹拉米洞法的血红蛋白检测结果受所有动物的血红蛋白影响。利用单克隆抗体法,上消化道出血的检出率为92%,下消化道肿瘤检出率为88%,常规粪便标本的隐血检出率为9%,利用改良的匹拉米洞法,上消化道出血的检出率为92%,下消化道肿瘤的检出率为72%,常规粪便标本的隐血检出率为13%。结论:单克隆抗体法测定大便隐血,具有更高的准确性以及特异性,2种方法对于当今的大便隐血常规测定来说都非常重要,可采取互补利用的方法来提高测定精度以及扩大适用范围。
