Abstract

We have developed and validated an MRM-MS assay for quantifying AFP-L3 in human serum to diagnose early-stage hepatocellular carcinoma. LiBA, the current standard method, cannot measure AFP-L3 concentrations accurately due to its low sensitivity. We addressed this issue with immunoprecipitation in conjunction with fractionation with LCA lectin. Consequently, the MRM-MS assay identified hepatocellular carcinoma patients that were missed by LiBA. In addition, we validated this approach in accordance with several multinational guidelines such as FDA, EMA, and CLSI. Our results demonstrated that this assay is robust and immediately applicable in clinical practice.
