CA19-9 is the common term for carbohydrate antigen sialyl Lewis a. It is a protein found on the surface of certain cancer cells. It may be found in the blood when it is shed by cancer cells.

CA19-9 is commonly used as a tumour marker for some types of cancer of the pancreas. But this test cannot be used by itself to find pancreatic or other cancers because:

CA19-9 is also found in healthy adults in small amounts in the pancreas, liver, gallbladder and lungs. About 5% of people do not produce CA19-9, so this test cannot be used for them. The blood levels of this antigen may also be at a higher than normal level in healthy people and in people with non-cancerous conditions such as pancreatitis or bile duct obstruction.
