Liver tumor-associated antigen determination includes alpha-fetoprotein, alpha-fetoprotein heterogeneous body and other liver cancer serum markers.
1. Alpha-fetoprotein (AFP): it is a commonly used indicator in clinical diagnosis of hepatocellular carcinoma and has relative specificity for hepatocellular carcinoma. Elevated AFP is also one of the current diagnostic criteria for liver cancer.
2. Alpha-fetoprotein heterogeneous body: suitable for differential diagnosis of patients with elevated alpha-fetoprotein. It can be used in differential diagnosis with hepatitis, cirrhosis and gastrointestinal tumors.
3. Other hepatocellular carcinoma serum markers: suitable for the diagnosis of alpha-fetoprotein negative hepatocellular carcinoma. Including glutamyl transpeptidase isoenzyme and abnormal prothrombinogen, which can be used as auxiliary diagnostic indexes.
The specific problems of patients’ liver tumor diagnosis still need professional doctor’s guidance.
