A simple blood test may reveal kidney damage in lupus — no biopsy needed?
NCT ID NCT07763834
First seen Aug 13, 2026 · Last updated Aug 14, 2026 · Updated 1 time
Summary
This study asks whether levels of uromodulin, a protein in the blood, can indicate the severity of kidney damage in people with lupus nephritis. Researchers will compare uromodulin levels with kidney biopsy results from 90 participants, including those with different classes of lupus nephritis and active lupus without kidney involvement. If uromodulin correlates with biopsy findings, it could become a less invasive way to monitor the disease.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Uromodulin (a protein measured in blood as a potential biomarker)
- What this could lead to
- If uromodulin levels match biopsy results, it could offer a less invasive way to monitor kidney damage in lupus nephritis, potentially reducing the need for repeated biopsies.
- What could go wrong
- This is an early, observational study with a small number of participants. Uromodulin may not reliably reflect biopsy findings, and results may not apply to all patients.
