作者采用免疫羧化胶乳法和一组抗人大肠癌相关抗原的单克隆抗体，对５５４例人粪便中一组大肠癌相关抗原进行测定。结果表明：２８例大肠癌，其阳性率为９２．９％，特异性为１００．０％，正确指数为９２．８％；５例绒毛管状腺瘤均为阳性；４例管状腺瘤息肉阳性率为５０．０％；１１例炎性息肉阳性率为１８．２％；结肠炎、上消化道良性疾病、上消化道恶性肿瘤、正常人则均为阴性。研究提示：免疫羧化胶乳法检测粪便中一组大肠癌相关抗原敏感性好，特异性高。免疫胶乳法作为定性试验，不需要特殊仪器，操作简便，快速，便于掌握推广，适用于群体大肠癌普查。
The authors used the immunocarboxylated latex method and a panel of monoclonal antibodies against colorectal cancer-associated antigens to determine a group of colorectal cancer-associated antigens in 554 human feces samples. The results showed that: 28 cases of colorectal cancer, the positive rate was 92.9%, the specificity was 100.0%, the correct index was 92.8%; 5 cases of villous tubular adenoma were positive; 4 cases of tubular adenomatous polyp positive The rate was 50.0%; the positive rate of 11 cases of inflammatory polyps was 18.2%; colitis, benign diseases of the upper gastrointestinal tract, upper gastrointestinal cancer, and normal persons were all negative. The research suggests that the immunocarboxylated latex method has a good sensitivity and specificity in detecting a group of colorectal cancer-associated antigens in feces. As a qualitative test, the immune latex method does not require special instruments. It is easy to operate, fast, and easy to grasp and popularize. It is suitable for colon cancer screening.
