2023年6月7日 · The CA 19-9 test is a tumor marker blood evaluation to measure the body’s response to cancer treatment. Learn the normal ranges and how to evaluate results. We're available 24/7.

2022年8月11日 · A CA 19-9 test measures the amount of a protein called CA 19-9 (cancer antigen 19-9) in a sample of your blood. CA 19-9 is a type of tumor marker. Tumor markers are substances made by cancer cells or by normal cells in response to cancer in your body.

The CA 19-9 Radioimmunoassay (RIA) is a simple blood test that measures the level of tumor-associated antigens found in the blood. CA 19-9 associated antigen levels are elevated in many patients with pancreatic cancer.

This test measures levels of CA 19-9 in the blood and it is most often used to monitor cancers of the pancreas or bile ducts. Because levels of CA 19-9 are also raised with other cancers and some benign conditions the test is not specific enough to be used for diagnosis.

CA 19-9 (Carbohydrate Antigen 19-9) is a protein that is produced by normal cells but is often elevated in certain types of cancers. It is primarily associated with pancreatic cancer but can also indicate other conditions like gallbladder cancer, liver disease, or benign disorders.

2024年7月18日 · CA 19-9 levels are considered to be normal if they are under 37 U/mL. High CA 19-9 levels are typically above 37 U/mL, and may be a sign of cancer, typically pancreatic cancer. High CA 19-9 levels can also be above 37 U/mL with health conditions like pancreatitis, bile duct obstruction or liver cirrhosis.

Carbohydrate antigen 19-9 (CA19-9) is a protein found on certain types of cancer cells, including pancreatic and biliary tract cancer cells. It can also be found in the pancreas, liver and gallbladder of healthy adults. A CA19-9 test measures the amount of CA19-9 in the blood.

Carbohydrate antigen 19-9 (CA 19-9) is a modified Lewis(a) blood group antigen. CA 19-9 may be elevated in patients with gastrointestinal malignancies such as cholangiocarcinoma, pancreatic cancer, or colon cancer.

This test looks for the antigen called cancer antigen 19-9 (CA 19-9) in your blood. Antigens are substances that stimulate your body's immune system. Some types of cancer cells send CA 19-9 into the blood, where it can be measured with this test.

The CA 19-9 marker is associated with cancers in the colon, stomach, and bile duct. Elevated levels of CA 19-9 may indicate advanced cancer in the pancreas , but it is also associated with noncancerous conditions, including gallstones, pancreatitis, cirrhosis of the liver, and cholecystitis.
