Blood test; kidneys values

[vexotex]

Ahh but it is. While they are indeed two different things using Creatine (which, if not used by the body will be broken down and will show up as Creatinine).

Mayoclinic states: Generally, a high serum creatinine level means that your kidneys aren't working well. Your creatinine level may temporarily increase if you're dehydrated, have a low blood volume, eat a large amount of meat or take certain medications. The dietary supplement creatine can have the same effect

In effect it gives a false positive or more accurately the waste or unused material gives a high level. Ergo advice is to not use any Creatine for a few days pre a blood test.
As a lifter who has been tested my muscle breakdown has never shown as a higher than normal level. But, as you say, it is what happens biologically speaking.

I know that, elevated creatinine is a sign kidneys can’t properly maintain they function anymore. But up to what level is tolerable regarding I train in gym 5 times per week and eat meat and take roids? I mean how high creatinine do have some serious bodybuilders and still don’t worry?

This is why you'd want to either ease of or stop training for a couple of days as well as no creatine (as per my reply earlier). Then, instead of having the lab freak out at the potential results, you'd get a truer picture from the blood tests. As for what figures I've no idea. I'm no doc and I don't do blood tests. But I DO KNOW both, as per Trevor's reply (and yours too above) and mine that both exercise AND using Creatine could give higher than normal reading.

All that said it's just ONE measure in a series of measures. And, if it came back high, the doc and the lab ought to check with you - as in 'does he train 5 days a week, what's his protein intake like and does he supplement with Creatine'. Or you could also mention it. They then ought to say 'have a week off, then we will do another test' etc etc

All common sense really

Thanks for reply. Yeah, I see I have to stop for some time and clean my kidneys if it isn’t to late

What I suggest is not 'cleaning your kidneys'. It's, as I said, just ensuring a true set of values on the test
