CA19.9

Understanding CA19.9

CA19.9, a carbohydrate-rich glycoprotein known as mucin, is an important biomarker associated frequently associated with pancreatic cancer. However, increased CA 19.9 levels may also be seen in other cancers, including colorectal, gastric, hepatobiliary, and ovarian cancer. Additionally, the levels of CA19.9 may be elevated in non-cancerous conditions such as pancreatitis, cirrhosis, benign gallbladder disease (cholestasis), and cystic fibrosis. Hence, it is important to note that a CA19.9 test is not a standalone...

What does CA19.9 measure?

A CA19.9 test, also known as carbohydrate antigen 19.9, is a blood test used to measure the levels of CA 19.9 protein in the blood. CA 19.9 is a tumor marker that may be increased in individuals with certain types of cancer, particularly pancreatic cancer and some non-cancerous conditions. This test helps diagnose cancer, monitor cancer treatment response, and detect cancer recurrence post-treatment.
