Your kidneys filter your blood by removing waste and extra water to make urine. The glomerular filtration rate (GFR) shows how well the kidneys are filtering. An estimated 37 million adults in the United States may have chronic kidney disease (CKD) but nearly 90% are unaware of their condition.
Healthcare providers use estimated glomerular filtration rate (eGFR) to determine if you have kidney disease, and if so, what stage. eGFR measures your kidneys’ ability to filter toxins or waste from your blood. A very low number may indicate kidney failure, which requires dialysis or a kidney transplant. Find a Primary Care Provider.
Each stage is determined by a blood test known as the estimated glomerular filtration rate (eGFR), which establishes how well your kidneys filter waste and excess fluid from your blood.
Your eGFR is an estimated number based on a blood test and your age, sex, and body type. eGFR is considered a mostly reliable test for doctors to know how well your kidneys are working. However, the eGFR may not be accurate if you are younger than 18, pregnant, very overweight or very muscular.
Your kidneys filter your blood by removing waste and extra water to make urine. The best way to know how well your kidneys are filtering the blood is to look at your estimated glomerular filtration rate (eGFR). Your eGFR is calculated using your serum (blood) creatinine level, age, and sex.
How well are your kidneys working? Explaining your kidney test results. Your GFR result on ___________ (Date), was _________. A GFR of 60 or higher is in the normal range. A GFR below 60 may mean kidney disease. A GFR of 15 or lower may mean kidney failure. What is GFR? GFR stands for glomerular filtration rate.
An estimated glomerular filtration rate (eGFR) test is a blood test that’s used to figure out how well your kidneys are doing their job. The test measures the amount of creatinine in your blood and, using a formula, mathematically derives a number that estimates how well your kidneys are functioning. The formula uses your creatinine levels ...
