Of 1400 patients who were submitted to the Haemoccult test, 46 showed a postive result. Among other things there were 29 polyps, of which 3 already showed a focal carcinoma, and 5 carcinomata of the large intestine and 3 gastric carcinomata were also diagnosed. Over 70% of the tumor hosts had observed bleeding per anum at some time. In order to detect the number of false nagative results, patients were investigated in the same way even when the Haemoccult test had been negative three times. In this way 55 polyps were found as well as 7 partly advanced carcinomata of the large intestine. 35% of the Haemoccult-negative patients stated bleeding per anum in their history. The number of false negative findings must be considerably higher than previously estimated.
在接受潜血试验的1400名患者中，46人结果呈阳性。除此之外，有29个息肉，其中3个已显示局灶性癌，还诊断出5例大肠癌和3例胃癌。超过70%的肿瘤患者曾在某些时候出现过便血。为了检测假阴性结果的数量，即使潜血试验已三次呈阴性，也对患者进行同样方式的检查。通过这种方式，发现了55个息肉以及7例部分进展期的大肠癌。35%潜血试验阴性的患者称其有便血史。假阴性结果的数量肯定比之前估计的要高得多。
