Creatinine Scare

Out of all the lab test results, the first one I check is my creatinine levels. This is a good estimate of how well your kidneys are filtering the toxins out of your blood. The normal range is from 0.7 to 1.3 mg/dL for men. Post-transplant, my levels are a bit above the high end, but my nephrologist says that is typical.

During the past month, I have had many lab tests done, mainly because of the two ankle surgeries. Here are the results:

As evident from the results, my creatinine level fluctuate wildly. My nephrologist did say that test results, and actual kidney function, is highly dependent on hydration levels. Still, I was freaked out by the 2.23 number on January 8th so my nephrologist ordered another test. She just called today and was fine with the 1.58 result. I really do not want to deal with kidney issues while I am still one-legged.
