Tests, tests, tests: Tests results always have to be interpreted in a context. When they measure the temperature of the winner of the Boston Marathon 2 yrs ago it was over106 F. Was he very ill? NO! He had been using his bodies muscles at full output for over 2 hrs straight. The heat generated raised his body temp a lot and he soon cooled off. You hv to talk with yr doc or make a virtual consult. ...Read more

What happens when creatinine level is higher than normal range?

It depends : Muscular people have higher creatinine levels. When I was lifting weights semi-seriously, mine ran 1.7 or so. It's fine. Much of the current obsession with minimally increased creatinine levels reflects medico legal concerns that may require adjusting drug doses. If your BUN is up, your urinalysis abnormal, or your ability to concentrate your urine is poor, you might have real kidney disease. ...Read more

What does it mean if my CREATININE LEVEL is always 118 or 119 uMOL/L? The normal range is 50-120. For the 8th time, my CREA is always 119.

Could just be you: Reference ranges are set for couch-potatoes and if you're a well-muscled man, you'll have creatinine high, often above the "normal". And ranges are set arbitrarily to have a few percent of healthies outside on either end. Keep managing your hypertension and don't worry so much about creatinine. ...Read more

Last September 15, my CREATININE is 81.54 uMOL/L. The normal range is 50.0--120.0. This November 9, my CREATININE LEVEL is 124.53. Unsafe?

Here are some ...: Some fluctuation in the report of a test result may fluctuate reflecting the time of testing and exercise; I would not overly concern such with no practical need to often repeat testing it as long as you've been living healthy and well. Besides, your profile seems suggesting some personal trait of obsession, which needs to be modified & balanced so to live a longer happier life. Of course, ask Doc ...Read more

33 year old husbands blood creatinine level is 1.18( ref. Range is 0.50-1.20). Is this on the high end of normal, and should we be worried?

Creatinine of 1.18: You should ask your physician for her thoughts on your husband's creatinine (c) level. It is still normal and would be nice to know if were the same level last year, or if it were increasing. At this level, in the absence of an increase c level, i would speak to his physician and not be too concerned. If it is increasing see a nephrologist for better management of it. ...Read more

My 2 year old had labwork yesterday and her creatinine level was 0.26 with a listed standard range of 0.30 to 0.70. Is this a cause for concern?

No: Reference ranges are set so that several percent of healthy folks fall outside on either end. That's so as not to miss stuff. Kids tend to run low in any case. ...Read more
