PROVIDER INITIATED TEST - The CA 19-9 test measures the level of cancer antigen 19-9, a protein that may be elevated in certain gastrointestinal cancers, most commonly pancreatic cancer. This test is primarily used to monitor treatment response, assess disease progression, or detect recurrence in individuals with a known cancer diagnosis, rather than as a screening test.
CA 19-9 levels may also be elevated in non-cancerous conditions such as gallstones, pancreatitis, liver disease, or bile duct obstruction. Results are interpreted in combination with clinical findings, imaging studies, and other laboratory tests.
