Glomerular filtration rate (GFR)
Glomerular filtration rate (GFR)
- This test is meant to measure the efficiency through which kidneys flush out waste from the body
- Overnight fasting is required. Also avoid eating red meat few days before the test
- The test is important for people with active kidney disease or suspicion of kidney disease due to Blood Pressure of Diabetes.
What is Glomerular filtration rate (GFR) Test ?
The kidneys remove excess fluid and waste materials by a filtration process known as Glomerular filtration. It is a calculation of the rate that determines the efficiency of the filtration process, thus helping measure kidney functioning and to determine the stage of the chronic kidney disease. At times a person who is a kidney patient and needs to undergo a contrast CT Scan or MRI Scan, GFR rate becomes very important. If your GFR is very low then you cannot undergo a contrast study.
Reported Parameters
- The normal level of GFR is considered at 60 or above
- A below 60 GFR test result may indicate kidney-related diseases
- A below 15 GFR test results may indicate severe kidney failure

- High blood pressure
- Tiredness
- Swelling around eyes
- Muscle cramps
- Change in the frequency of urination
- Decrease in the amount of urine
- Dark urine
- Mid back pain
- Problems urinating
- Burning sensation during urination
- Swelling in the face, around eyes, ankles, wrists and abdomen.
The GFR test is a blood test and needs overnight fasting. It is also advisable to avoid red meat before taking the test as red meat can increase the serum creatinine which can impact the GFR.
