摘　　要：目的:探讨胶体金法和邻甲苯胺法检测空腹患者胃液潜血的差异.方法:收集58例大于24 h未进饮食(为肠外营养)、3 d内未吃肉类食品、未服用Vc、铁剂等影响邻甲苯胺法检测药物的胃插管患者的胃液标本,用胶体金法和邻甲苯胺法同时检测潜血.结果:胶体金法有31例阳性,阳性率为53.4%,邻甲苯胺法有44例阳性,阳性率为75.9%,两者有显著性差异(P<0.005).结论:邻甲苯胺法检测空腹患者胃液潜血优于胶体金法.AIM： To explore the relationship and differences between the one step fecal occult Blood Test and 2-aminotoluene assay to detect occult blood in gastric juice from patients who did not consume a meal, METHODS： Fifty-eight samples of gastric juice were collected from gastric catheterization patients who had fasted for at least 24 h （parenteral nutrition）, and who had not consumed meat, Vitamin C or iron for 3 d. The one step fecal occult Blood Test and 2-aminotoluene assay were used to examine occult blood in human gastric juice. RESULTS： The positive rate for the one step fe- cal occult Blood Test was 53.4% and 75.9% for the 2-aminotoluene assay. This difference was significant （P 〈 0.005）, CONCLUSION： The positive rate for the one step fecal occult Blood Test is lower than that for the 2-aminotoluene assay from the patients who have fasted,
