GFR Calculator
Enter your information below to calculate your glomerular filtration rate (GFR).
Your GFR is: mL/min
Glomerular Filtration Rate:
The glomerular filtration rate (GFR) is a measure of how well the kidneys are filtering waste products from the blood. The normal GFR varies according to age, sex, and body size. In young adults, it is approximately 120 mL/min/1.73 m2 and declines in normal individuals with age. However, a decrease in GFR may also be a marker of kidney disease and precedes the onset of kidney failure. The standard way to estimate GFR is with a simple blood test that measures creatinine levels.Here are the standard GFR ranges:
*GFR of 90 or higher is in the normal range. *GFR of 60-89 may mean early-stage kidney disease.
*GFR of 45-59 may mean mild kidney disease.
*GFR of 30-44 may mean moderate kidney disease.
*GFR of 15-29 may mean severe kidney disease
*GFR below 15 may mean kidney failure.
It is important to note that these ranges may vary slightly depending on the laboratory and the method used to calculate GFR. It is recommended that patients discuss their GFR results with their healthcare provider to determine what the results mean for them.
