What is the CA19-9 tumor marker?

CA 19-9 is a tumor marker commonly associated with pancreatic cancer. The normal range of CA 19-9 in the blood of a healthy individual is 0-37 U/mL (units/milliliter). People suffering from pancreatic cancer often have elevated levels of CA 19-9. However, it is important to note that not every patient with pancreatic cancer will have elevated levels of CA 19-9.
