Overview


What is GFR?

Glomerular filtration rate (GFR) is also known as the estimated glomerular filtration rate (eGFR). This test is advised to evaluate kidney function. It helps to diagnose stage and monitor chronic kidney disease.



Why is GFR done?

The glomerular filtration rate is done:

  • As a part of routine tests along with blood creatinine test

  • In case of signs of kidney damage

  • In case of the risk of developing kidney disease


What does GFR Measure?

Glomerular Filtration Rate (GFR) helps in measuring the function of kidneys. Glomeruli are present in the kidneys. They are tiny filters that allow waste products to be removed from the blood. They prevent the loss of important constituents including blood cells and proteins.


Normally healthy kidneys filter about 200 quarts of blood and produce approximately 2 quarts of urine. The GFR is the amount of blood which is filtered by the glomeruli per minute. At the time of kidney function damage or disease, there is a decrease in the filtration rate. This results in the piling up of waste products in the blood. 


The chronic kidney disease (CKD) is related with a progressive decrease in kidney function. CKD might be seen in conditions such as diabetes and high blood pressure. Early detection of kidney dysfunction can help to minimize further kidney damage. This is important as symptoms of kidney disease are usually noticeable only after there is a loss in 30-40% of kidney function.

Answers to Patient Concerns & Frequently Asked Questions (FAQs) about GFR


Frequently Asked Questions about Glomerular Filtration Rate

Q. What are the signs and symptoms of kidney disease?
The signs and symptoms of kidney disease include swelling or puffiness, particularly around the eyes or in the face, wrists, abdomen, thighs, or ankles. Additionally, foamy, bloody or coffee-colored urine, decrease in the amount of urine, problems in urinating such as burning feeling or abnormal discharge at the time of urination can be observed. One may also experience change in frequency of urination, especially at night, mid-back pain in the area where the kidneys are located, and high blood pressure.
Q. What are the signs of worsening of kidney disease?
The signs of worsening of kidney disease include urinating more or less often, feeling itchy, feeling of tiredness, and loss of concentration. One may also experience signs like loss of appetite, nausea, vomiting, swelling, numbness in hands and feet, darkening of the skin, and muscle cramps.
Q. What other tests can be advised to detect kidney damage or disease or to evaluate kidney function?
The other tests which can help to evaluate kidney function include Urine albumin and albumin/creatinine ratio (ACR). Along with that, complete urine examination may also be advised.
Q. How is the blood sample taken?
The healthcare provider takes a blood sample from the arm. The site from where the blood is to be withdrawn is cleaned with a swab of rubbing alcohol. This is then followed by inserting a small needle which has a tube attached to it for collecting blood. Once the sufficient blood for analysis is withdrawn, the needle is removed. The site is then covered with a gauze pad.
Q. Is there any risk associated with the withdrawal of blood sample procedure?
As such there is no risk but in few cases, bruising, bleeding, and infection at the puncture site can be seen. In very few cases, there can be swelling of the vein after the blood is withdrawn.
