Which numbers are especially important in predicting kidney healthâand what's in the normal range? Estimated GFR number â Measures kidney function, over 60 is normal, under 60, talk to your doctor. GFR, or glomerular filtration rate, tells you how well your kidneys are doing their job of filtering the blood.
The level of creatinine in the blood is a useful guide to kidney function, but GFR (glomerular filtration rate) is a more accurate measure. Blood creatinine can be used to estimate GFR (eGFR) using age, sex, and race, and this is often calculated by computer and reported along with the creatinine blood test. If it isn't but you know the creatinine result, you can use our eGFR calculator. Normal GFR is approximately 100mls/min/1.73m 2. The kidneys filter approximately 100mls/min, or 150 litres per day.
