Bead‐by‐bead normalization of single antigen assays: A necessary step for accurate detection of weak anti‐HLA antibodies
5 Sept 2024
Abstract excerpt
Ascertaining the presence of weakly positive anti-HLA donor-specific antibodies (DSA) in organ transplantation with multiplex single antigen beads assays may be challenging despite their high sensitivity due to technical variability issues. Through extensive datasets of Next-Generation Sequencing HLA typings and single antigen analyses, we reassessed the mean fluorescence intensity (MFI) positivity threshold of...
