Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a prospective, multi-center, observational study. Subjects will have OmniGraf™ (TruGraf® and TRAC™) testing at study enrollment and thereafter every 3 months. In addition subjects will have OmniGraf™ (TruGraf® and TRAC™) testing at any time there is a clinical suspicion of acute rejection. Data collection for the primary objective extends over a 2-year period.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Several studies have validated TruGraf® in stable renal transplant patients to rule out subclinical acute rejection. These studies generally evaluated the diagnostic value of TruGraf® at single timepoints. Thus the value of serial monitoring and changes over time has not been previously investigated. In addition, no study has assessed TruGraf® and TRAC™in a serial and longitudinal fashion.

Therefore the aim of this study is to evaluate the impact of serial monitoring renal transplant patients with both TruGraf® and TRAC™ on long term outcomes.
