About this Calculator
This GFR Calculator can help you with detecting a kidney disease at its early stage.
What is eGFR?
Estimated Glomerular Filtration Rate (eGFR) is a test that shows how well your kidneys are working. It determines the amount of blood that your kidneys filter every minute which is critical since healthy kidneys get rid of waste and excess fluid in your body.
Rather than directly measuring kidney function (which is challenging), eGFR is estimated by a formula which incorporates your blood creatinine level, age, sex and, in some cases, race or body size. Creatinine is a by-product of muscle metabolism and when the kidneys fail to remove it, creatinine accumulates in the blood.
