Screening for Monoclonal Gammopathy in Individuals Undergoing Physical Examinations Using iMS-LC Assay Technology.

"iMS-LC Assay (intact M-protein Screening-Light Chain Assay) technology is a new method for the specific identification of M-proteins in peripheral blood, based on mass spectrometry recognition of intact clonal immunoglobulin light chains. Combined with AI algorithm models, M-proteins can be easily distinguished from the polyclonal background, enabling automated identification and quantitative analysis of M-proteins.~Previous studies have shown that the detection limit of the iMS-LC Assay is several times higher than that of IFE. Additionally, the iMS-LC Assay requires only 5 μL of peripheral blood serum for detection, offering advantages over traditional methods in terms of higher sensitivity, non-invasiveness, lower sample volume requirements, reduced detection costs, and higher throughput."
