Abstract: An object of the present invention is to provide a method for collecting highly accurate data for diagnosis, useful in diagnosing the presence or absence of extrahepatic bile duct carcinoma, intrahepatic bile duct carcinoma, or gallbladder carcinoma, and a kit for diagnosis.When the concentration of CEACAM1 in a blood sample collected from a test subject is detected using a kit for diagnosis comprising an antibody specifically binding to CEACAM1 or a labeled product thereof, or the like and the CEACAM1 concentration is higher than the concentration of CEACAM1 in a blood sample derived from a non-carcinoma control subject or higher than a certain threshold value (cutoff value), data can be collected for diagnosing the test subject as having a high possibility of having extrahepatic bile duct carcinoma, intrahepatic bile duct carcinoma, or gallbladder carcinoma.
