Ca 19-9 is a substance that is released into the blood by the pancreatic cancer cells.This marker test is performed by taking a small amount of blood and testing it. A normal Ca 19-9 in a healthy individual can range from 0-37 U/ml.here are a small number of people whose pancreatic cancers do not shed the Ca 19-9 substance. Their tumor marker test for Ca 19-9 will always come back low, irregardless of whether the cancer is growing or gone.
