Overview
There are some diagnostic laboratory findings associated with gallbladder cancer, such as alkaline phosphatase, serum bilirubin, carcinoembryonic antigen (CEA), CA 19-9.
Laboratory tests
There are no diagnostic laboratory findings associated with gallbladder carcinoma.[1][2]
Laboratory findings consistent with the diagnosis of gallbladder carcinoma include:
- 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 have lack of specificity and sensitivity.
- CA 242 is a tumor marker for gallbladder cancer and performs better than CEA and CA 19-9.[3][4]
- 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.
