Kidney function est: Estimating kidney function is just that, an estimate. There are a few ways to actually measure kidney function, but for most people an estimate by blood testing is adequate. Unfortunately the equations that report GFR are very very inaccurate in higher levels of kidney function. At my clinic we stop reporting the exact estimate and instead simply record it as 60+ as a way to reassure our patients.
