I’ve heard the term GFR.
What does this mean?
Glomerular Filtration Rate (GFR) is the rate that the kidney filters the blood per minute. It is the best measure of kidney function and is a rough indicator of how well your kidneys are working. Normal GFR is 90-120 mL/min (180 L/day), and is higher in men than women. The lower the GFR, the worse your kidney function. This puts you at a greater risk for developing kidney disease.
How do I find my GFR?
You don’t find it… the blood lab does! Many GP offices run this test when they send off your bloodwork for routine physicals. (All the more reason to keep up with your annual checkups!)
Does my GFR determine if I have CKD?
Target GFR is around 100 mL/min; however, a low GFR is only one finding and does not always manifest in CKD’s early stages. You can have CKD even with a normal GFR! Scary, right? Look for protein in urine or even abnormal findings on your kidney ultrasound.
GFR is not an exact science…. it’s only an ESTIMATE!
The number is not always accurate for the malnourished, obese, pregnant, amputated and/or people under 18 years old.
