Brief Summary

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

This is an observational study to evaluate TruGraf® testing in high immune risk kidney transplant recipients. TruGraf is the first and only non-invasive test approved by Medicare to rule out silent rejection in stable kidney transplant recipients.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* High immune risk kidney transplant recipients defined by one of the following criteria: either a positive pretransplant donor specific anti-human leukocyte antigen (HLA) antibody, or a pre-transplant panel reactive antibody \>75%.
* Recipient of a primary or subsequent deceased-donor or living donor kidney transplantation.
* Stable serum creatinine (current serum creatinine \<2.3 mg/dl, \<20% increase compared to the average of the previous 3 serum creatinine levels).
* Kidney transplant patients who are at least 30 days post-transplant.

Exclusion Criteria

* Need for combined organ transplantation with an extra-renal organ and/or islet cell transplant.
* Recipients who do not meet criteria of high-immune risk.
* Recipients of previous non-renal solid organ and/or islet cell transplantation.
* Infection with HIV.
* Infection with BK.
* Patients that have nephrotic proteinuria (urine protein \>3 gm/day).
