GFR Calculator - eGFR Calc is an iPhone application designed to accurately measure your level of kidney function and determine the stage of kidney disease. Developed by Dang Phan, this free app provides a convenient way for doctors and patients to calculate the estimated glomerular filtration rate (eGFR) using various equations.

The app offers five different equations for calculating eGFR, including CKD-EPI Creatinine (2009), Cockcroft-Gault, MDRD, CKD-EPI cystatin C (2012), and Bedside Schwartz for children and individuals under 19 years old. By inputting your blood creatinine test results, age, body size, and gender, the app can help your doctor determine your stage of kidney disease and plan the appropriate treatment.

GFR Calculator - eGFR Calc also provides a handy table that compares GFR indicators with the stages of chronic kidney disease, allowing users to better understand their condition. For any additional requests or upgrades, you can contact the developer at
