Americans 50 years of age and older are advised to test their stools for occult blood to detect colorectal neoplasms. Many will be taking 1,300 mg of aspirin daily because of cerebrovascular disease or smaller amounts for cardiovascular disease. To determine if 1,300 mg of aspirin causes positive hemoccult II tests, 27 healthy volunteers ate a red meat-free, high-fiber diet. Their stools were negative for occult blood during a 3-day control period and remained negative while they took 1,300 mg aspirin daily for an additional 7 days. This indicates that 1,300 mg aspirin daily for 1 week does not cause positive hemoccult II testing. Those taking this dose of aspirin probably need not interrupt therapy to perform hemoccult II testing.
建议50岁及以上的美国人检测大便潜血以发现结直肠肿瘤。许多人因脑血管疾病每天服用1300毫克阿司匹林，或因心血管疾病服用较少量的阿司匹林。为了确定1300毫克阿司匹林是否会导致隐血试验II呈阳性，27名健康志愿者食用不含红肉的高纤维饮食。在为期3天的对照期内，他们的大便潜血呈阴性，在接下来的7天每天服用1300毫克阿司匹林期间，大便潜血仍为阴性。这表明连续1周每天服用1300毫克阿司匹林不会导致隐血试验II呈阳性。服用此剂量阿司匹林的人可能无需中断治疗来进行隐血试验II检测。
