Objectives: To find the role of urinary retinol binding protein 4 (RBP-4) compared to serum creatinine, as a better predictors of impaired renal function in patients with type 2 diabetes. Methodology: In this cross sectional study, 60 patients with T2D and 20 controls were included. Age of patients was in the range of 35-60 years with duration of diabetes
