Cancer Antigen CA 19-9 Blood Test (Labcorp)
The Cancer Antigen (CA) 19-9 test is often used to aid in the diagnosis of Pancreatic Cancer. CA 19-9 is a protein found on the surface of some cancer cells. CA 19-9 is elevated in about 70-95% of pancreatic cancer cases. It can also be elevated in cases of colorectal cancer, lung cancer and gallbladder cancer. While a CA 19-9 test can be used to differentiate types of cancer or monitor response to treatment, it is not sensitive enough to be used as an initial screening by itself.
A CA 19-9 test is often ordered with other tests such as a CEA, Hepatic Function, or Bilirubin when a person is experiencing symptoms associated with Pancreatic Cancer. It is also used to monitor how well a person is responding to treatment for pancreatic cancer. Because not every person with pancreatic cancer will show elevated levels of CA 19-9, this test will not always be an effective tumor marker.
Turnaround time for the CA 19-9 test is typically 2-4 business days.
