A Study of Transplant Organ Genomics to Help Prevent Rejection in Kidney Transplant Recipients with Realtime Assay Monitoring


About this study

The purpose of this study is to connect the findings of TruGraf (a peripheral blood RNA signature that has been shown to correlate with rejection in kidney transplants) with rejection episodes in kidney transplant patients that are managed using standard of care clinical protocols at the three Mayo transplant sites.
