Group I included 30 healthy peoples with estimated glomerular filtration rate (eGFR) > 60 mL/min/1.73 m2 and urine albumin creatinine ratio (uACR) < 30 mg/g. Group II included 30 type 2 diabetic patients having uACR < 30 mg/g, eGFR > 60 mL/min/1.73 m2. Group III included 30 type 2 diabetic patients having uACR > 30 mg/g, eGFR > 60 mL/min/1.73 m2.Results: Urine KIM-1 and NGAL increased progressively from control group (57.29 ± 25.91 pg/mL; 25.71 ± 13.69 ng/mL) to the group of diabetic patients with uACR < 30 mg/g (167.06 ± 44.01 pg/mL; 37.42 ± 10.89 ng/mL) and the group of diabetic patients with uACR ≥ 30 mg/g) (p < 0.05). There were moderate correlations between KIM-1 (r = 0.48, p < 0.05) and NGAL (r = 0.45, p < 0.05) with uACR. There was a mild correlation between KIM-1 and NGAL (r = 0.29, p < 0.05). KIM-1 and NGAL are the independent tests to detect diabetic nephropathy. The sensivity and specificity of KIM-1 with cut-off value of 174.95 pg/mL were 62.37% and 73.48%, respectively; the sensivity and specificity of NGAL with cut-off value of 35.2 ng/mL were 60.45% and 70.37%, respectively.Conclusion: KIM-1 and NGAL in urine are independent markers for early diagnostic diabetic nephropathy.Keywords: diabetic kidney disease, urine albumin creatinin ratio, albumin urine
