• This test measures the amount of a protein called CA 19-9 (cancer antigen 19-9) in the blood. CA 19-9 is a type of tumor marker. Tumor markers are substances made by cancer cells or by normal cells in response to cancer in the body.
  • A CA 19-9 blood test may be used to:
    • Monitor pancreatic cancer and cancer treatment. CA 19-9 levels often go up as cancer spreads, and go down as tumors shrink.
    • See if cancer has returned after treatment.
  • The test is sometimes used with other tests to help confirm or rule out cancer.
  • CA 19-9 testing methods and results can vary from lab to lab.
  • If you are getting tested regularly to monitor treatment for cancer, you may want to talk to your health care provider about using the same lab for all your tests, so your results will be consistent.
