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.
