I had an idea my TSH might have risen as I have thyroid type symptoms again and haven't been feeling as well as I was. I decided it was time for a retest before adjusting my meds. Back they came yesterday. The receptionist cheerfully informed that they were all "normal, no action". I smiled sweetly down the phone at her, resisted all temptation to tell her that I wasn't interested in her or the lab's interpretation, and thanked her kindly when she offered to print them out for me. (They all know I ask for print outs).
The tests clearly show why I've gone downhill. My TSH has risen from 0.2 to 2.5 and my GFR has fallen from 64 to 60.
I'm going to raise my thyroxine back to 50mcg (from 25mcg). I also take nutri thyroid, but as I don't appear to have a conversion problem I'm going to let the NHS pay for T4. I'm also going to raise my alpha lipoic acid and go back to drinking green and detox teas.
You see. The blood tests DO tell you what's going on if you take a few short seconds to look for changes.
