I went to the RA doc this week and had a blood test. I got a call from the physicians assistant telling me that my kidney function test was high. I asked her what that meant and she said she was only an assistant. I had to wait until I met with the doc in six weeks. Okay...

I got my test results today and the result that has her concerned is my CREATININE. I know what you are thinking, what is creatinine? Creatinine is a breakdown product of creatine, an important part of muscle. It is a waste product that's produced by your muscle metabolism and to a smaller extent by eating meat. Healthy kidneys filter creatinine and other waste products from your blood. The filtered waste products leave your body in your urine.

These test results show my creatinine is high. The normal range is 0.40 - 0.80. I showed a 0.93.

After doing some Internet research, I am only slightly concerned. There are a lot of things that can make a test result high. Dehydration, my medication. In six weeks I should get tested again and see if I still have high creatinine results. If I do then there is another test that includes urine. How exciting! I get to pee in a cup for 24 hours. Guess I will have to work from home. That isn't exactly an activity I can do when I am at a clients office.

Big weekend ahead. I have to get some sleep.

Until tomorrow...


  1. Are you on MTX? My creatinine was mildly elevated while I was on it. Also, if you do a fasting blood test and haven't had very much in the way of liquids that morning, it will appear elevated as well. I wouldn't worry unless the follow-up is elevated also. And drink plenty of water! :)

  2. No I am no longer on MTX. I had a bad reaction to it after being on it for years. I may have been a little dehydrated. I was at a clients all day and some times I forget to drink water when I am working. I guess I will find out in 5 weeks. Thanks for the help!


Would love to hear what you have to say!
