Thyroid blood tests

[saloplass]

Can any moderator please type up what the 'normal' ranges are for all types of blood tests relating to the thyroid. I realise that we shall vary one to another, but I need to understand exactly what the normal ranges are and what they mean. For years I suffered with CU and dermographism, itching 24 x7 and I found that when I was put on T3 any my levothyroxine was lowered my itching seemed to lessen. This could of course have been a fluke, but??? Thank you.

Thanks - personally do not believe in my case itching could be due to fillers - hives accompany my itching, and I can literally draw on my skin when flaring is bad. But thanks for your input.

I know people say it can't be the Levothyroxine itself, but I am beginning to think it is in my case.

I never have suffered from hayfever - but I have found I cannot stay in the poison section like weed killer, etc in a garden centre. However, my flares of CU come and go which I presume they would not if it was due to the drugs?

You can never presume anything when it comes to thyroid.

Optimal is not a question of numbers, it is when all your symptoms have gone. And that is different for everybody. Lab ranges are just a guide.

A guide yes, but seems GPs do not understand a great deal about thyroid bloods, especially if they are against T3 or even checking it. Or perhaps I was extremely unlucky! We all need to take more control of our own health problems and do our best to educate ourselves. To learn from our doctors, they must be good, informed and willing to explain.
