Hepatocyte Specific Antigen

Hepatocyte Specific Antigen antibody (HSA) is considered very specific for normal and neoplastic hepatocytes. Expression has been demonstrated consistently in the majority of hepatocellular carcinomas. Studies have shown HSA to be an effective marker that may be used in a panel with CEA (Carcinoembryonic Antigen), CK7, AFP (Alpha Fetoprotein) and CD10 to aid in the differential diagnosis of hepatocellular carcinoma from cholangiocarcinoma and/or metastatic adenocarcinoma.
