To assess in diabetic nephropathy, the accuracy of estimated creatinine clearance (calculated with the Cockroft Gault formula) and the clearance of the Tc99m-DTPA, to measure the glomerular filtration rate (GFR).We analysed the GFR measure by Tc99m-DTPA method and the estimated by the Cockroft Gault formula, in 21 subjects with type 1 or type 2 diabetes.There was a strong positive correlation between the two methods but the Cockroft Gault formula underestimated the GFR.The formula gives a accurate estimates of GFR, when GFR is
