The article focuses on the study of early diagnosis of colorectal cancer. The detection of occult blood in faeces is at present the only practical method of population screening for colorectal cancer and can be performed using a guaiac-impregnated slide test such as Haemoccult. Its use in studies will be discussed with particular reference to compliance, yield, workload generated and false-negative rate. The diagnosis by occult blood tests depends on tumors bleeding into the lumen of the bowel.
