ALB and type 2 diabetes mellitus: Pro-oxidant biomarkers (total oxidant status (TOS) and pro-oxidant-antioxidant balance (PAB)) and biomarkers of oxidative damage (ischemia-modified albumin (IMA) and advanced oxidation protein products (AOPP)) were significantly increased in T2DM patients (p < 0.001), while antioxidant defense biomarkers (total antioxidant status (TAS), total sulfhydryl (SH) groups) were significantly reduced (p < 0.001).
