Testing Immunosuppression Threshold in Renal Allografts To Extend eGFR

This study evaluates the addition of "Kidney Solid Organ Rejection Test" (kSORT), in the clinical follow-up of renal transplant recipients, compared to clinical standard surveillance in the first two years after kidney transplantation. The design of the study is a partially blinded, randomized control trial of patients with living and deceased donor. The recruitment will be in a third level attention hospital in Mexico city (Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán). The main outcomes are the rate and grade of acute rejection, histologic chronic index of the one year protocol biopsy and glomerular filtration rate.
