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.
Glomerular filtration rate (GFR) is the best overall index of kidney function. Normal GFR varies according to age, sex, and body size, and declines with age.
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. GFR is a measure of how well your kidneys filter blood. Your urine albumin result on _____________ (Date), was ___________.
An eGFR lower than 15 is a marker of kidney failure. You may notice your eGFR number go up or down slightly between tests. This is normal. When trying to understand your eGFR number, it is usually better to look at the general pattern over time rather than one specific lab result.
A GFR of 90 or higher is considered normal if you're healthy unless you have other symptoms such as protein in your urine, which could still be a sign of kidney disease. If you have...
Like other kidney tests, a normal GFR number for you will depend on your age and sex.
A GFR lower than 15 mL/min/1.73 m2 is a sign of kidney failure and requires immediate medical attention. Lower than normal GFR may indicate: Too little blood flow to the kidneys; Loss of body fluids (dehydration) Heart or liver disease leading to circulatory system changes that affect the kidneys; Damage to the filtering units of the kidneys
