GFR (glomerular filtration rate) is equal to the total of the filtration rates of the functioning nephrons in the kidney. GFR is considered the optimal way to measure kidney function, which in conjunction with urine albumin-to-creatinine ratio (UACR), can help determine the extent of chronic kidney disease (CKD) App allows medical professionals to estimate kidney function using eGFR (Glomerular Filtration Rate) Calculator: * MDRD GFR Equation * Creatinine Clearance (Cockcroft - Gault Equation) * CKD-EPISODE Equations for GFR - 2021 - CKD-EPI Creatinine - 2021 - CKD-EPI Creatinine -Cystatin C - 2009 - CKD-EPI Creatinine - 2012 - CKD-EPI Cystatin C - 2012 - CKD-EPI Creatinine -Cystatin C
