Is GFR the same as PERCENTAGE OF FUNCTION?

My father has kidney function of 20%.   Does that mean his glomerular filtration rate is 20, or is that something different?  Thank you.

Glomerular filtration rate is not the same as a percentage function but it could be seen as somewhat similar.  GFR is an estimate of the amount of mililiters of blood your kidneys filter every minute.  If GFR = 20, then it would mean the kidneys filter about 20 mL of blood every minute.  I'd say an average person has a GFR of about 100 mL / min so essentially you could almost look at kidney function of 20% = GFR of about 20 mL / min.  

Hope that makes some sense.
