What does a GFR of 113 mean?

A GFR of 113 means that your kidneys are functioning well. The glomerular filtration rate (GFR) is a measure of how well your kidneys are filtering waste products from your blood. A normal GFR is between 90 and 120 milliliters per minute per 1.73 square meters (mL/min/1.73 m2). A GFR of 113 means that your kidneys are filtering 113 milliliters of waste products from your blood each minute. This is considered to be within the normal range.
