Normally normal adult blood glucose chain antigen 199 (CA199) levels are <37u/ml , and its elevation may be for malignant diseases such as pancreatic and bile duct cancers as well as benign diseases such as cholecystitis.
CA199 is a kind of salivary acidified Lewis blood group antigen in the body, salivary glands, prostate, pancreas and other glands, epithelium of stomach, bile ducts, gallbladder and other organs can be detected in trace amounts of CA199.Normal human blood CA199 is measured by ELISA at a level of <37.00u/ml, which can be different from one laboratory to another.
When pancreatic tumor occurs, the level of CA199 in blood can be significantly increased, the specificity of CA199 for pancreatic cancer is up to 95%, and it can be used as the first choice of tumor marker. In addition, gallbladder cancer and bile duct cancer can also be screened with this index.
However, it should be noted that acute pancreatitis, cholangitis, acute hepatitis and other diseases will also increase the index to different degrees. Abnormalities in this indicator are recommended to consult a doctor in time.
