Non-HLA antibody trajectories may predict kidney transplant outcomes

These findings suggest that longitudinal trajectories of non-HLA PRA, rather than staticmeasurements or DSA status alone, may influence graft loss. The dynamic nature of non-HLA antibody responses and supports integration of non-HLA antibody profiling into longitudinal immune monitoring frameworks. Larger multicenter studies are needed to define clinically meaningful threshold and estabilish the utility of non-HLA PRA testing across diverse transplant populations.
