Kidney glomerular filtration rate (GFR) is a test performed by a simple blood test and used to check how well your kidneys are working by estimating how much blood passes through the glomeruli, tiny filters in the kidneys that filter waste from the blood. per minute. Kidney Glomerular Filtration Rate number is considered by medical professionals to be the best measure of your kidney function and it is a key indicator of renal function.
Estimated GFR Number by Age Group
| Age | Mean Estimated GFR (mL/min/1.73 m2) |
| 30-39 | 107 |
| 40-49 | 99 |
| 50-59 | 93 |
| 60-69 | 85 |
| 70+ | 75 |
Besides the blood test result other factors are factored in to determine your GFR number. These factors include:
- Age
- Height
- Weight
- Gender
- Ethnicity
- Blood Creatinine
- Creatinine Clearance Test
GFR Number by Age
The normal range of Kidney Glomerular Filtration Rate is 100 to 130 mL/min/1.73m2 in men and 90 to 120mL/min/1.73m2 in women below the age of 40.
GFR decreases progressively after the age of 40 years.
