The significance of early identification of Diabetic Kidney Disease (DKD), a significant complication leading to End-Stage Kidney Disease (ESKD), is highlighted by the increasing frequency of diabetes worldwide. Using search phrases such as "diabetic kidney disease," "early biomarkers," and "laboratory markers," this study synthesizes material from PubMed, Medline, and Google Scholar to examine early laboratory biomarkers for quick Diabetic Kidney Disease (DKD) identification. The ability to detect early DKD is limited by the use of conventional markers such as albuminuria and Estimated Glomerular Filtration Rate (eGFR). Reflecting the underlying inflammatory processes, inflammatory biomarkers such as Monocyte Chemoattractant Protein-1 (MCP-1) and Tumor Necrotic Factor-Alpha (TNF-α) have emerged as possible early indications of DKD development and progression. Furthermore, tubular damage-related indicators including Kidney Injury Molecule-1 (KIM-1) and Vitamin D-Binding Protein (VDBP) have the potential to identify early renal impairment. Beta-2 Microglobulin (B2M) and urine type IV collagen are examples of glomerular damage indicators that are linked to structural abnormalities in DKD, which may help with early identification. Pentosidine and the oxidized DNA nucleoside 8-oxodG are two examples of oxidative stress indicators that show promise in predicting macrovascular and microvascular problems in DKD. These biomarkers provide light on the etiology and course of DKD, giving medical professionals useful instruments for prompt intervention and treatment.
