GFR is a test that helps measure the level at which an individual's kidney is functioning. It is calculated on the basis of factors such as age, gender, race, and blood creatinine. Normal GFR values are between 90 to 120 ml/min. A GRF below 60 ml/min could mean that some kidney damage has occurred.
The blood test, called GFR, measures how much blood your kidneys filter each minute. Your doctor uses this information to see how well your kidneys are working. A GFR of over 60 means your kidneys are working fine. A GFR of 60 or lower may mean you have kidney disease.
