My grandson was recently sent for tests by a dermatologist who was suspicious about his thyroid levels. They did usual tsh and t4 and gp says all ok......I know it is best to get t3as well but nhs won’t do it and having a problem with private test as he is only 14. Can you please give me your opinion, I know with a t4 like his I would be very poorly indeed, but his tsh to me is also low. Am I wrong.
Serum TSH 0.68 range. 0.30 to 4.80
T4. 9.2. Range 7.2 to 20.60
No, you're not wrong. Both his TSH and his FT4. And if your doctor knew anything about thyroid, that would make him suspect Central Hypo, and test FT3 to confirm it. But, the NHS thinks Central Hypo is very, very rare so they don't even teach it in med school. They are wrong.
Central Hypo is when there is a problem with the pituitary (Secondary Hypo) or the hypothalamus (Tertiary Hypo) rather than the thyroid itself (Primary Hypo). Not enough TSH is secreted to stimulate the thyroid to make hormone, so levels drop. I think you should suggest this idea with however ordered the tests. But, do read up on it a bit, first, so that you sound as if you know what you're talking about. 
Thank you that is exactly what I thought but needed someone to confirm it.
Happy to be of service.
On researching I have found a link between central hypo and short arm X chromosome which he has.....think we have a long fight on our hands but knowledge is power. Thank you again
For full Thyroid evaluation he will need TSH, FT4, FT3 plus TPO and TG thyroid antibodies and also very important to test vitamin D, folate, ferritin and B12
As dermatologist raised the issue, does your grandson have vitiligo? Or hives?
Private Thyroid tests are available. Thousands on here forced to do this as NHS often refuses to test FT3 or antibodies or vitamins

Medichecks Thyroid plus ultra vitamin or Blue Horizon Thyroid plus eleven are the most popular choice. DIY finger prick test or option to pay extra for private blood draw. Both companies often have money off offers.
All thyroid tests should ideally be done as early as possible in morning and fasting.
Grandson has hives on face with swollen lip. We have enquirer about private tests but as he is under 16 we had no luck
