Details of Glomerular Filtration Rate ( GFR )
What is a glomerular filtration rate ( GFR ) test?
A glomerular filtration rate (GFR) is a blood test that checks how well your kidneys are working. Your kidneys have tiny filters called glomeruli. These filters help remove waste and excess fluid from the blood. A GFR test estimates how much blood passes through these filters each minute.

A GFR can be measured directly, but it is a complicated test, requiring specialized providers. So GFR is most often estimated using a test called an estimated GFR or eGFR. To get an estimate, your provider will use a method known as a GFR calculator. A GFR calculator is a type of mathematical formula that estimates the rate of filtration. It does this by comparing the results of a blood test that measures creatinine, a waste product filtered by the kidneys, with other information about you. This information includes some or all of the following:
  • The results of a blood test that measures creatinine, a waste product filtered by the kidneys
  • Age
  • Weight
  • Height
  • Gender
  • Race
The eGFR is a simple test that can provide very accurate results.

Other names: estimated GFR, eGFR, calculated glomerular filtration rate, cGFR
What is it used for?
A GFR test is used to help diagnose kidney disease at an early stage when it is most treatable. GFR may also be used to monitor people with chronic kidney disease (CKD) or other conditions that cause kidney damage. These include diabetes and high blood pressure.
Why do I need a GFR test?
Early-stage kidney disease doesn’t usually cause symptoms. But you may need a GFR test if you are at higher risk of getting kidney disease. Risk factors include:
  • Diabetes
  • High blood pressure
  • Family history of kidney failure
Later-stage kidney disease does cause symptoms. So you may need a GFR test if you have any of the following symptoms:
  • Urinating more or less often than usual
  • Itching
  • Fatigue
  • Swelling in your arms, legs, or feet
  • Muscle cramps
  • Nausea and vomiting
  • Loss of appetite
What happens during a GFR test?
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.
Will I need to do anything to prepare for the test?
You may need to fast (not eat or drink) or avoid certain foods for several hours before the test. Your health care provider will let you know if there are any special instructions to follow.
Are there any risks to the test?
There is very little risk to having a blood test. You may have slight pain or bruise at the spot where the needle was put in, but most symptoms go away quickly.
