GFR Calculator
Estimate your Glomerular Filtration Rate to assess kidney function.
What is GFR?
Glomerular Filtration Rate (GFR) is a test used to check how well the kidneys are working. Specifically, it estimates how much blood passes through the glomeruli each minute. Glomeruli are the tiny filters in the kidneys that filter waste from the blood.
Interpreting the Results
The eGFR (estimated GFR) is the best way to measure your level of kidney function and determine your stage of kidney disease. Your doctor can calculate it from the results of your blood creatinine test, your age, body size, and gender.
Maintaining Kidney Health
To keep your kidneys healthy, it's recommended to stay hydrated, maintain a healthy weight, monitor your blood pressure, and limit the intake of salt and processed foods. Regular exercise and avoiding smoking also play a key role.
