Glomerular Filtration Rate Test

Also known as: GFR.

What is a glomerular filtration rate test?

Glomeruli act as filters for the kidneys, removing waste from the blood. A glomerular filtration rate test checks how well the kidneys are working by measuring how much blood flows through the glomeruli in a minute.

What happens during the procedure?

A routine blood draw is required in order to begin the glomerular filtration rate test. The blood sample is then taken to a laboratory, where the glomerular filtration rate test begins.

Is any special preparation needed? 

In most cases, no special preparation is needed for the test. The patient may need to stop taking certain medications, such as antibiotics and stomach acid medications, prior to the test.

What are the risk factors?

Infection, bleeding, lightheadedness and damage to surrounding organs and tissues are potential risks of the blood draw that takes place prior to glomerular filtration rate test.
