"just out of range", classic NHS. You are hypothyroid. No wonder you are having symptoms. I don't know how you are functioning with a tsh that high.


Hi.....thank you for replying, I do function slowly, but I find that I am making silly mistakes, my brain is so muddled at times and I feel like i am drunk although i don't drink alcohol, I am putting on weight and get tired easily, I was diagnosed 7 years ago and have good days and bad days, I work 30 hours a week and that is enough, I will ask my GP to refer me to a endocrinologist.


High creatinine is an indicator or kidney problems (but they didn't do BUN so can't be sure)

High Red blood cell distribution width generally means you are anaemic - What's your B12 and folate like?

Low MCHC can mean iron deficency, too. So get ferritin tested.

You can look up results on labtestsonline.org

What's the point of ranges if they don't treat when you are outside them or view the very "edges" of the ranges as possible problem areas?


Hi...Thank you for your reply, it is true what you say, what is the point of ranges, I shall see my GP for a referral to see the endocrinologist,


Don't expect too much, they will probably refuse a referral because your results are "normal". That's how they play the game


refuse me........omg i thought i was special............lol...........i know what you mean, cut backs and denial of what caused this, of course it is not the chemical food we eat.....
