Diagnostic Performance of Donor-derived Cell-free DNA Combined With Immune Activation Markers for Detecting Acute Rejection After Liver Transplantation.
BACKGROUND Accurate differentiation of acute rejection (AR) from other causes of graft dysfunction after liver transplantation remains challenging in real-world clinical practice. Although donor-derived cell-free DNA (dd-cfDNA) has emerged as a promising non-invasive biomarker of graft injury, its specificity may be li...
