Understanding the test
What does the CA-19-9 test measure?
Also called Pancreatic & GI Marker
A specialist may request a baseline or serial CA 19-9 in the management of selected pancreatic or biliary cancers.
When it may be requested
Supporting follow-up
CA 19-9 can assist monitoring in selected pancreatic or biliary cancers when a specialist considers it appropriate.
Interpreting an increase
Bile duct obstruction and inflammation are among the possible non-cancerous causes.
Before your sample
Prepare for collection
SpecimenSerum
Your checklist
No fasting is generally needed. Mention jaundice, gallstones or a recent bile duct stent or drain before comparing CA 19-9 results.
A clinician takes a small sample of blood from a vein. The laboratory uses serum, the liquid separated from the blood after it clots.

Reading your result
CA 19-9 can rise with obstruction or inflammation and may be low even when disease is present. A trend should be interpreted in the clinical setting in which it was obtained.
What can affect it
- Some people produce little or no CA 19-9, even when disease is present.

Patient questions
Before you book
Why can jaundice complicate a CA 19-9 result?
Impaired bile flow can raise the marker independently of cancer. The clinician may interpret it alongside bilirubin, imaging and changes over time.
Is CA-19-9 only linked to pancreatic cancer?
No. Pancreatic cancer is the cancer it is most strongly associated with, but cholangiocarcinoma and other cancers of the bile ducts also raise it, as can gastric, colorectal and some ovarian and lung cancers. A raised value therefore does not point to one organ on its own, and imaging is what locates the source.
Why should I use the same laboratory for CA-19-9 monitoring?
Values from different assays are not directly comparable, so switching laboratories can create an apparent change that is really a difference in method. Because the trend is what your doctor reads, give each sample through the same laboratory where possible and bring your previous results, so each new value can be set against the ones before it.
