Re: High TSH in 7.6 yr old girl??

TSH in a prepubertal child should never be higher than 5.5. Free T3 is so rarely tested, I can find no guideline about pediatric levels for it. The reference range given for free T4 is .8 - 2.2; the level for most healthy euthyroid children would be somewhere in the center of that range, no less than about 1.5.

Don't let this get pushed under the rug. Something is not right about a TSH that high. Make sure tests for thyroid (TPO and Tg) antibodies are run, too. Those will indicate if she has inherited the autoimmune cause of hypothyroidism.
