Your health care provider will let you know if there are any special instructions to follow. A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out.
This usually takes less than five minutes. 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. The glomerular filtration rate measurement comes from the name of the filtering units inside your kidneys, called the glomeruli. Glomeruli are complex structures made of tiny blood vessels called capillaries, along with protein mesh and layers of tissue that continuously filter your plasma.
Based on research , between your 2 kidneys, you have about 2 million glomeruli. But the measurement essentially takes into consideration your gender, age, body size, and your blood creatinine level. Creatinine is a waste product that your body creates as muscle breaks down.
Everyone has some creatinine in their blood. Average levels range from:. These levels can vary. For example, in a research review , creatinine levels fell by an average of 0. Because they can change with age and size, creatinine levels alone are not good indicators of kidney health.
The GFR takes these other elements into account. Most GFR results simply provide you with a measurement of 60 or higher, since you can have stage 1 or 2 kidney disease, but still have normal kidney function. This changes when your GFR drops below Under 60, you begin to have some loss in function. As you advance through the stages of kidney disease, you will notice more and more symptoms, and your treatments may need to become more intense.
Hemodialysis is a treatment where an artificial kidney filters and circulates your blood when your kidneys can no longer do their job. However, with early diagnosis and careful management, you may be able to at least slow down the progression of your kidney disease. In most cases, kidney disease is a chronic and gradually progressing disease.
For most people with chronic disease, positive lifestyle changes may help slow the loss of kidney function. Some studies have shown that GFR may increase over time in people at all stages of kidney disease by:. With proper management, you may never need dialysis or, at least, not for a very long time.
But if your kidneys fail, we will need to choose a treatment that can replace the job of your kidneys to maintain health. There are two types of dialysis - one is done at home daily and the other is done in a dialysis center three times a week. Is kidney transplant an option? You may be able to receive a kidney transplant. The donated kidney can come from an anonymous donor who has recently died or from a living person.
A kidney transplant is a treatment - not a cure. View Advanced Health Information Search. How well are your kidneys working? 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? A urine albumin result below 30 is normal. A urine albumin result above 30 may mean kidney disease. What is urine albumin?
