Through the Looking Glass: Unraveling the Stage-Shift of Acute Rejection in Renal Allografts.

Sub-optimal sensitivity and specificity in current allograft monitoring methodologies underscore the need for more accurate and reflexive immunosurveillance to uncover the flux in alloimmunity between allograft health and the onset and progression of rejection. QSant-a urine based multi-analyte diagnostic test-was developed to profile renal transplant health and prognosticate injury, risk of evolution, and resolution of acute rejection. Q-Score-the composite score, across measurements of DNA, protein and metabolic biomarkers in the QSant assay-enables this risk prognostication.
