Alpha-Fetoprotein (AFP) L3% and Total, Hepatocellular Carcinoma Tumor Marker, Serum
Use
This test is useful for distinguishing between hepatocellular carcinoma and chronic liver disease. It can also be used for monitoring individuals with hepatic cirrhosis for progression to hepatocellular carcinoma and for surveillance of hepatocellular carcinoma development in individuals with a positive family history of hepatic cancer or specific ethnic and sex groups with chronic hepatitis B infection acquired early in life.
Special Instructions
Not provided.
Limitations
AFP testing may have reduced specificity since increased AFP levels can also occur in other conditions such as chronic hepatitis and liver cirrhosis. AFP alone should not be relied upon for hepatocellular carcinoma diagnosis. AFP or AFP-L3 is not interpreted properly if the patient is pregnant. Additionally, some tumor cases do not produce AFP at all. Test interference may occur in the presence of human anti-animal antibodies, and results need careful clinical correlation.
