目的：分析免疫法、化学法便潜血试验对消化道出血性疾病误诊的原因，探讨免疫法、化学法粪便潜血试验联合应用的价值。方法消化内科粪便样品300例，使用化学法和免疫法分别检测，对潜血试验结果比较，并进行分析讨论。结果免疫法和化学法阳性率及真阳性率比较差异有统计学意义(P<0.01)。结论免疫法应用于上消化道出血性疾病的诊断应慎重，而对于下消化道出血性疾病则是首选，应将两种方法联合应用于粪便常规检查和体检普查项目，并结合受检者自身情况进行综合判断，以免造成漏诊和误诊。

Objective To analyze misdiagnosed reason of digestive tract hemorrhagic disease by immune method and chemical method fecal occult blood test, and to investigate combined application value of immune method and chemical method fecal occult blood test. Methods There were 300 feces samples from department of digestive medicine. Chemical method and immune method were applied to detect the samples, and comparison was made on the results of occult blood test for analysis and discussion. Results The difference of positive rate and true positive rate between immune method and chemical method had statistical significance (P<0.01). Conclusion Implement of immune method should be cautious in diagnosis of upper gastrointestinal tract hemorrhagic disease, while it is the preferred method in diagnosing lower gastrointestinal tract hemorrhagic disease. Combination of the two methods ought to be used for fecal routine and physical examination, and comprehensive judgment needs to be made by individual condition of patients so as to avoid missed diagnosis and misdiagnosis.
