NCT00381121: University of Michigan kidney research biobank

This is the University of Michigan Nephrology Research BioBank, an observational research resource rather than a treatment trial. Participants' clinical information, blood, and urine are collected; when a kidney biopsy is already performed for clinical care, a remaining sample can be reserved after diagnostic requirements are met. Researchers use the material to investigate molecular and genetic features of kidney disease. 1 2

The inspected registry version, updated April 18, 2025, listed 420 estimated participants and a recruiting status. That is a projected enrollment and a dated registry statement, not confirmation that 420 people were enrolled or that participation is available today. 1 2

Its intended contribution is better understanding of disease mechanisms and potential biomarkers. The record does not demonstrate that joining the biobank improves kidney function or that a new diagnostic marker has already been clinically validated. 1 2
