Hello and thanks in advance, a little bit of background info im worried about my 7 year old son, i scott have graves and my son was probably conceived when i was undiagnosed. My son has autistic spectrum disorder with an underline learning difficulty, My son is very tall and has big feet for age and can eat and eat and still be skinny he is also very flexible ie both feat behind back of neck and lots of energy same as i when i was a child, So heres the results im sorry its only the nhs so i only have the tsh 4.09 and his free t4 was 15.3. I was expecting hyper results but unless im having a graves moment even with a 1 to 5 range that the nhs stick to thats nearly at the top of the range and if it was the usa standered that would be subclinical hypo or have i got this wrong. Second question if i were to use one of the online pharmacy mention on the thyroid uk site what test should i have done and mums worried that is this legal to do this on a minnor with the home test kits. Thanks very much for your time on this if you need more info just ask.
