Doctor explains Ca 19-9 blood test used in PANCREATIC CANCER | LAB TESTS explained

In this video Doctor O'Donovan explains the Ca 19-9 lab test including 1. What Ca 19-9 is 2. Why the test is used 3. What the result of the test might mean.

Cancer antigen 19-9 (CA 19-9) is a protein that exists on the surface of certain cells. CA 19-9 does not cause cancer; rather, it is a protein that is produced by the tumour cells, making it useful as a tumour marker to follow the course of the cancer.

CA 19-9 is elevated in most patients with advanced pancreatic cancer, but it may also be elevated in other cancers and diseases such as bowel cancer, lung cancer and gall bladder cancer, as well as in benign diseases such as gall stones, pancreatitis, cystic fibrosis, and liver disease. Because elevated levels of CA 19-9 are seen in many diseases, elevated levels do not necessary mean the presence of pancreatic cancer. Very small amounts of CA19-9 may also be found in healthy patients

My mom recently passed from pancreatic cancer four months after being diagnosed. A later came from genetic that she had BRCA II and I tested positive as well. I’m here because one of my test came back in the 40s which is considered high….

[randyrogers]

I have multiple IPMN cysts on my pancreas. Fortunately, my CA19-9 levels are always well within normal limits. (Last reading was 13) I still get a CTscan every six months to play it safe. So far so good.

Can you please tell us some common CA-19 numbers from pancreatic stage 4 patients at or near death? My 87 year old grandfather has stage 4 pancreas cancer, his CA-19 number was around 2, 000 a few months ago, and is now over 5, 000. It appears to be growing 1k every month. I'm just wondering how long he might have to live.

Hello doctor, thank you for the information. Just wondering; how common is it for the antigen 19-9 levels to drop, even though the pancreatic tumor continues to grow? In these cases, what could be the factors contribhtig to the contradiction?

If you have a lack of Lewis expression of blood type, one will be negative for Ca19-9. I have an Anti Lewis A1C and my Ca19-9 was negative. It should of been Positive.
