Better tests to predict how donated kidneys will work after transplant

What this research studies

This project looks at proteins in urine collected from people who donated kidneys after death to find signs of a kidney's ability to repair itself. Researchers will measure repair biomarkers such as YKL-40, uromodulin, and osteopontin in donors who had acute kidney injury or high KDPI. They will pilot real-time point-of-care urine tests on samples from about 500 donors and link those findings to how well the transplanted kidneys work in recipients over time. The work is done with organ procurement organizations and transplant centers so test results could be used during organ allocation decisions.

Who could benefit from this research

Good fit: People on the kidney transplant waiting list or patients receiving kidneys from deceased donors—especially transplants involving donors with acute kidney injury or high KDPI—are the most likely to benefit.

Not a fit: People who are not candidates for kidney transplantation or those receiving living-donor kidneys are unlikely to benefit directly from this work.

Why it matters

Potential benefit: If successful, this could help more good kidneys get transplanted and reduce the number of usable kidneys that are unnecessarily discarded.

How similar studies have performed: Earlier phases of this program found promising links between donor urine repair biomarkers and long-term graft function, and this phase is testing real-time point-of-care use of those markers.
