What is cancer antigen Gi 19-9?

You may need a CA 19-9 blood test if you’ve been diagnosed with pancreatic cancer or other type of cancer related to high levels of CA 19-9. These cancers include bile duct cancer, colon cancer, and stomach cancer. Your health care provider may test you on a regular basis to see if your cancer treatment is working.

What is a cancer antigen number?

A cancer antigen number is also called a tumor marker. It is a number that indicates the amount of cancer antigen in the body. A cancer antigen is a protein made by cancer cells. Different types of cancer can make different types of antigens, like a signature.

What are normal CA 19-9 levels?

The normal range of CA 19-9 is between 0 and 37 U/mL (units/milliliter), but people with pancreatic cancer often have higher levels. Not every pancreatic cancer will cause elevated levels of CA 19-9, and some non-cancerous conditions (like pancreatitis and jaundice) can cause high levels of CA 19-9.

What does it mean if cancer markers are high?

Higher tumor marker levels may indicate a certain type of cancer. A tumor marker test may be used as a part of your initial diagnosis. Guide treatment decisions. Some tumor marker tests tell doctors if they should give chemotherapy or immunotherapy.

What is the range of cancer antigens?

Reference Range. Cancer antigen 15-3 (CA 15-3) is used to monitor response to breast cancer treatment and disease recurrence. The reference range of serum CA 15-3 is less than 30 U/mL. The upper limit of the range varies depending on the laboratory and kit used for the test.
