eGFR is a measure of how well your kidneys are working. It is often reported automatically when you do a creatinine blood test, as a part of your comprehensive metabolic panel (CMP). Read on to learn more about this marker, what it means when your values are outside of the normal range, and how you can increase your eGFR levels.
What is eGFR?
GFR
Glomerular Filtration Rate (GFR) is the amount of blood filtered every minute by tiny filters in the kidneys called glomeruli. Although it may sound complicated, in essence, it measures how well your kidneys are working [1].
The main job of our kidneys is to remove waste and excess water from the blood. This excess water and waste become urine. Kidneys process about 50 gallons (180 liters) of blood every day to produce about 50 ounces (1.5 liters) of urine. When the filtration rate decreases that means the kidneys are not working well and may mean there is kidney damage [2].
