What is the Glomerular Filtration Rate?
Glomerular Filtration Rate (GFR) is the rate in which blood moves through miniscule kidney filters. The test is ordered as part of a kidney series to gauge kidney health. If creatinine levels are higher than normal a kidney panel may be ordered, including the GFR. Some of the conditions that may cause reduced kidney function include kidney disease, diabetes, hypertension and heart disease. As you age, GFR reduces, so age is taken into consideration when the test results are calculated. Other factors that affect GFR, aside from the disease process, include gender, race, weight and height.
