Hi all I feel a little pathetic as I know a gfr @85 is not that low but it is lower that the norm for my age which is 38. My concern is that my doctor has not mentioned anything it's only that I requested a copy of my blood test results that I know my gfr is 85. I would have thought that my doctor would have requested a urine samlple or am I worrying too much. My dad had pkd and died at the age of 54 so I do worry alot. I did have a ultrasound at 32 to check pkd which I requested and as far as I know it was fine.
