CA 19-9

Normal range: up to 37 IU/ml

Comment: CA 19-9 is a high molecular weight mucin found in the serum of many patients with pancreatic, GI and hepatobiliary malignancies. Levels are also raised, but less so, in chronic pancreatitis, cholecystitis and various types of cirrhosis of the liver. Amount of elevation has no relation to tumor mass, but test can be used to monitor the course of disease. Values of > 1000 U/ml indicate metastasis

Sample: serum
