Gfr Versus Kidney Function. The main difference between gfr and crcl is that gfr is the flow rate of filtered fluid through the kidney whereas crcl is the volume of blood plasma cleared of creatinine per unit time furthermore crcl is a useful measurement for approximating gfr. An egfr below 60 is a sign that the kidneys are not working well.
Further differences will be summarized in this article. Your doctor can calculate it from the results of your blood creatinine test your age body size and gender. Normal gfr is approximately 100 but you will often see it reported as 90 greater than 90 or 60 greater than 60.
Glomerular filtration rate gfr gfr or glomerular filtration rate shows how much blood your kidneys filter in 1 minute.
Your gfr number tells you how much kidney function you have as kidney disease gets worse the gfr number goes down. So this is the key difference between creatinine clearance and gfr. The normal range of kidney glomerular filtration rate is 100 to 130 ml min 1 73m2 in men and 90 to 120ml min 1 73m2 in women below the age of 40. Summary creatinine clearance vs gfr.
