Laurie, since you offered...
My 8 yr old dd has a TSH of 3.41 and is already over 100 lbs. even though she eats really healthy food and gets plenty of exercise. I am worried about early puberty. MD says that's a normal TSH and won't consider thyroid supplementation even though her mother (me), her grandmother and both aunts all have thyroid disorders.
TSH = 3.41 (.3 - 5.5)
T4 = 1.18 (.9 - 1.8)
T3 total = 227 (70 - 170)
Just a couple of thoughts come to mind. Every lab has their own normal range. I'm assuming the #'s in parentheses are the lab norms for the lab you used. The T3 is really high compared to the range, but the range you list seems narrow compared to what I've read online. WebMD lists the T3 normal range for a child 83-280 so your dd's is right in that range. But to go by your lab norms she shows an elevated T3. T3, as I understand it, is generally considered to be a better indicator. But an elevated T3 would indicate hyperthyroid and her symptoms are all hypothyroid.
Regardless, I think the medical community is starting to realize that what has passed for normal in the past is really not okay and that is the reason for the tightening of the lab ranges.
My only advise would be to try a different doc - one more progressive or holistic in his/ her approach to thyroid issues. Or, if you really like your doc and don't want to change you could ask for either a re-test periodically or a check of thyroid antibodies to see if an autoimmune response is occuring.
One other thing I want to throw out there is this: every person seems to have his/ her own ideal level for thyroid levels. I'm on a forum for parents of children with congenital hypothyroidism and often mom's post about how their child's labs came back in a good range and they have to fight with the doc to get med changes. They can see in their children's behavior that the thyroid isn't working well but it doesn't show up in the lab work. I think its an easier fight to win if you are a parent of a child who has already been diagnosed. But it may be worth another conversation with your dd's doc. Everything I have heard from the other parents and also what I have read says thyroid hormones do not have side effects. The danger really is only that you will force a swing to the opposite, which is easy to recognize if you know the symptoms and easy to fix if it occurs. I wonder if your doc would go along with a Synthroid trial if you promised to call him at the first sign of your daughter turning hyper?
