My eGFR bounces around from 36 to 51. Hydration is a big factor but there are mysteries. My doc says muscle wasting can make it go down, as can low blood pressure or heart issues. My doc does a Cystatin C which gives a different GFR not influenced by those other factors and while my creatinine based one was 36-41, my Cystatin C was 51-55.
