Hi Dublin!
Please let me start out by saying that I am not a medical professional. I can tell you that since I donated in October 2009, my new normal creatinine level seems to be 1.1. I did get one lab that came back at 1.2 about 5 months after I donated, but I was also a bit dehydrated. (I had some other labs done at the same time, so hadn't had anything to eat or drink since the night before.) I was told they were not at all concerned with the 1.2 result. Other than that one time, 1.1 has been normal for me (and no protein for me either). I believe it is important that the levels stay consistent, if they were to begin to elevate, that would then be a concern. Also, if you were at all dehydrated, that can cause creatinine to go up as well.
In my opinion, if your doctor is not concerned, you have no protein in your urine, you feel good, and your levels stay 1.2 or better, I think it sounds like you are doing very well! Congratulations!!
