| Use: | The Wako LiBASys method is used. Results obtained with different assay methods or kits cannot be used interchangeably. The Wako AFP-L3% assay is intended as a risk assessment test for the development of hepatocellular carcinoma in patients with chronic liver diseases. Elevated AFP-l3% values have been sown to be associated with a seven-fold increase in the risk of developing hepatocellular carcinoma within the next 21 months. Patients with elevated serum AFP-L3% should be more intensely evaluated for evidence of hepatocellular carcinoma. The result is not interpretable as a tumor marker in pregnant females. |
