Interesting, because a 90 is Stage 1, as is every number 90 and above. Yes, even healthy kids and younger adults with 130 or 140 have Stage 1 kidney disease, according to the following:

I would say you are at the high end of good function for your age, just as I am.

That decline is programmed in to the eGFR calculation. Every year, the number must go down, which means if you maintained the same eGFR for a couple years, you actually improved your kidney creatinine number a little each year. Do note creatinine numbers get a bit better if you become very sedentary, as it directly measures muscle breakdown, typically from using them.

Interesting!
