便血是结、直肠癌最主要的临床症状之一。如何通过一种简便、快速、精确、灵敏的隐血试验方法早期明确便血原因已成为众所关注的问题。为此,我们自1997年3月至12月间,同时用联苯胺化学法和单克隆免疫抗体法对78例结、直肠癌病人的粪便隐血进行前瞻性比较研究。 材料与方法
Blood in the stool is one of the main clinical symptoms of colorectal cancer. How to identify early causes of blood in the stool through a simple, rapid, accurate, and sensitive occult blood test has become a public concern. For this purpose, we conducted a prospective comparative study of fecal occult blood in 78 patients with colorectal cancer using benzidine chemistry and monoclonal antibody antibodies from March to December 1997.
