Serum Creatinine Giving False Positive Result
I just had my SERUM CREATININE. The result is 119.15 uMOL/L. The reference is 50.0--120.0. Is this alarming? What's the cure to this?

Depends who you are: I'm well-muscled and when I was lifting weights every day, my creatinine ran 1.6-1.8.

Please do not get in the habit of focusing on lab numbers when your child is healthy. He is healthy - enjoy! ...Read more
