Alpha Fetoprotein, Total and L3 Percent
Also known as: AFP L3
Use
The test is used for the surveillance and monitoring of hepatocellular carcinoma. The AFP-L3 Percent assay is intended as a risk assessment for the development of hepatocellular carcinoma in patients with chronic liver diseases. Elevated serum AFP-L3 percent values are associated with a seven-fold increase in the risk for developing hepatocellular carcinoma within 21 months. However, results cannot be interpreted as absolute evidence of the presence or absence of malignant disease.
Special Instructions

Limitations
Results obtained through this method cannot be used interchangeably with those from different assay methods or kits. The results are not absolute evidence of the presence or absence of malignant disease. For pregnant females, the test result is not interpretable as a tumor marker.
