Description:

Cancer Antigen CA 19-9 Blood Test

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.

Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.

Requirements:

It is recommended that someone taking Biotin (also known as vitamin B7 or B8, vitamin H, or coenzyme R) stop consumption at least 72 hours prior to the collection of a sample.
