Signal- and Bead-Dependent Inter-Operator Variability in Single-Center Luminex-Based HLA Antibody Testing
Background: Luminex-based single antigen bead assays are widely used for HLA antibody assessment in transplantation, but their semi-quantitative fluorescence outputs may be affected by technical, signal-dependent, and bead-specific factors. This single-center study evaluated inter-operator variability under routine lab …
