What is a CA 19-9 blood test?

A CA 19-9 test measures the amount of a protein called CA 19-9 (cancer antigen 19-9) in a sample of your 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[1] in your body.

Healthy people can have small amounts of CA 19-9 in their blood. High levels of CA 19-9 are often a sign of pancreatic cancer[2]. But high levels can also be a sign of other types of cancer or certain conditions that arent cancer. For example, gallstones[3] and cirrhosis of the liver[4] can cause high CA 19-9 levels.

Because high levels of CA 19-9 can mean different things, the test is not used by itself to screen[5] for or diagnose cancer or other diseases. But it can help monitor your cancer and check how well your treatment is working.
