We pay our respects to the ongoing living cultures of Aboriginal peoples, and to Elders past, present and future. Enter the required values to calculate the APRI value. eGFR calculator eGFR stands for estimated Glomerular Filtration Rate. A large simulation study compared eGFR by MDRD Study equation and estimated creatinine clearance (eCrCl) by the Cockcroft-Gault equation calculated from standardized creatinine values to each other and to measured GFR for the purpose of drug dosing. Kidney Health Australia respectfully acknowledges the traditional custodians of the land on which we operate our services.
