Diabetic kidney disease (DKD) is a frequent microvascular complication in individuals with type 2 diabetes mellitus (T2DM) and a major cause of chronic kidney failure worldwide. Chronic low-grade inflammation and platelet activation contribute significantly to renal microvascular damage. The purpose of this observational study is to evaluate whether routine blood test markers, specifically the Systemic Immune-Inflammation Index (SII), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and platelet indices (such as mean platelet volume \[MPV\] and platelet distribution width \[PDW\]), can serve as simple, accessible, and cost-effective biomarkers for identifying the presence and progression of diabetic kidney disease. Participants will include adult patients with type 2 diabetes categorized according to their urinary albumin-to-creatinine ratio (normoalbuminuria, microalbuminuria, and macroalbuminuria) as well as healthy control subjects. Complete blood counts, derived inflammatory indices, and renal parameters will be measured to assess their diagnostic accuracy for DKD.

Systemic Immune-Inflammation Index (SII) Level
Systemic Immune-Inflammation Index calculated as: Platelet count (10\^9/L) × Neutrophil count (10\^9/L) / Lymphocyte count (10\^9/L).
