Oxidized Albumin: An Emerging Biomarker Bridging Oxidative Stress and Renal Pathophysiology.

Oxidized albumin has emerged as a promising biomarker in blood for assessing oxidative stress and multiple organ dysfunction. Recent advances suggest its potential detectability in urine, offering a noninvasive avenue for early diagnosis and monitoring of kidney disease. This review synthesizes current knowledge on oxidized albumin, its pathophysiological relevance, and the evolving methodologies for its detection, highlighting its translational potential in clinical nephrology.
