CA 19-9 is a carbohydrate antigen found on the surface of cancer cells, primarily used to monitor pancreatic cancer treatment response and detect recurrence. It can also be elevated in bile duct, stomach, and colorectal cancers. Benign conditions like pancreatitis, gallstones, cirrhosis, and bile duct obstruction can also raise CA 19-9 levels. About 5–10% of the population cannot produce CA 19-9 due to Lewis antigen blood type status.
