Overview
There are no diagnostic laboratory findings associated with gallbladder cancer
Laboratory tests[1]
- Laboratory studies are usually nondiagnostic;
- An elevated alkaline phosphatase or serum bilirubin can be associated with bile duct obstruction.
- Serum tumor markers including carcinoembryonic antigen (CEA) or carbohydrate antigen 19-9 are frequently elevated, but they're no longer diagnostically useful because they lack specificity and sensitivity.
- CA 242 is a tumor marker for gallbladder cancer and performs better than CEA and CA 19-9
- However, if a tumor marker is observed to be elevated preoperatively, serial assay after resection may useful resource within the analysis of chronic or recurrent disease.
