GFR Estimated Lab for Kidney function

[Guest guest]

I just received my results for my GFR Estimated and it came back low at 86.

From what i'm reading a normal value for some one of my age, 28, should be

somewhere around 115. 86 puts me in the range of someone between the age of

60-69 y.o. I also read that a value of 86 suggests beginning stages of Kidney

Disease. Is this something that can easily be improved or is this a value that

is really stubborn and suggests i've done some real damage to my kidneys. I have

a phone consult with my doc in a week but till then any thoughts you all might

have are appreciated.
