About the test

CA 19-9 (Cancer Antigen 19-9) is a protein that may be elevated in the blood of individuals with gastrointestinal cancers, particularly pancreatic cancer. It is mainly used to monitor treatment response and disease progression, but it is not specific enough for early cancer detection, as levels can also rise in non-cancerous conditions like pancreatitis or liver disease.
