I just got back my latest blood test results, and my Creatinine went down about 11% from a year ago and saw my eGFR listed on my results as popping up, despite being a year older, which is good, because the eGFR formula artificially penalizes you for each year of age. I have never had a known kidney issue and now I am at a low Creatinine level that defines the lowest part of normal for me.

I did a sanity check against the National Kidney Foundation website’s current calculator. I get the same eGFR if I do not use the “Adjust For Body Surface Area” set of inputs. When I put in my height and weight and selected that I had a standard assay, my eGFR shot up over 30 points higher!

You see, the normal eGFR formula is a poor estimator of kidney function, yet, it’s the most common number used to tell us how bad our kidneys must be. It’s apparently far from true.

I have a Cystatin C test coming in today or tomorrow and I will see what it adds to the mix, as it could be more accurate.

Please plug in the numbers that matter to you and see what your CKD-EPI creatinine equation (2021) results are.

Thanks for the article. I’ll show this to my kidney specialist but I’m sure she’s aware of this already.

My eGFR has been fluctuating for the past few years. The last one went up and the kidney doctor was mildly surprised.

Major changes from a year ago include taking GlyNAC, Taurine, and Urolithin A for the past 3.5 months. I also use Pantethine now, for most of the past year, and I’ve been generally watching my carbs more closely, getting between 30-70 grams of net carbs a day.
