Just wanted to let you guys know about the eGFR (Kidney function) testing when you get bloods.
Some stuff that regular GP's are not aware of...
1.) Most of us know that if you train and are muscular that Creatinine (a by-product of creatine) levels will show up above normal range.
Also liver enzymes (ALT) will show up above normal range. We know that ALT is not just found in the liver but also in damaged muscle tissue. So if you are training hard every week and breaking down muscle you will have more ALT circulating in your blood, which can be misinterpreted as poor liver function by a GP.
2.) There is also a newer kind of kidney function test (eGFR) estimated Glomerular filtration rate. The lab calculates this using your age, weight, creatinine levels etc etc....
This can be inaccurate for people who consume high protein, creatine and are above their BMI due to extra muscle.
My recent bloods came back with elevated Creatinine and an eGFR of 66 (stage 2 kidney failure).
You can imagine my mental state when I left the GP's office.
After doing some internetting I found a ton of cases where bodybuilders/gym goers etc had experienced the same thing. A google search will also bring up real studies of people being diagnosed wrongly with kidney failure. These people are usually ingesting creatine and/or protein and lifting.
The eGFR is an "estimation" and a poor one. A more accurate test for kidney function for guys like us is a urine test.
I have a follow up appointment with an Endocrinologist (hormone specialist) to confirm all this.
GP's should be more educated on this stuff before they scare the crap out of people.
