Abstract: Objective　To evaluate the performance and clinical application of the fecal occult blood test kit by colloidal gold immunoassay.   Methods　A total of 150 stool samples were collected randomly from inpatients. The comparative determination of these samples were performed by experimental kit（bioMerieux Co., Ltd.） and control kit（Shanghai Chemtron Biotech Co., Ltd.）. The results were statistically analyzed. The primary clinical application was evaluated.   Results　The experimental kit had a good sensitivity （40 ng/mL）, and its specificity and repeatability met the needs of clinical application. The determination results suggested that it could be consistent with control kit results and clinical pathogenetic condition.   Conclusions　The fecal occult blood test kit by colloidal gold immunoassay is simple, reliable, and suitable for clinical application.
