TSH and thyroid questions

[gatorgal]

My 16yo dd, recently had some blood work. TSH 3.2 (.45-4.5), T4 12.7 (4.5-12) and T3 uptake 17 (23-35). Incidentally she has been on Yaz for 4 years for  excess androgens. Recently, her cholesterol(280)  and triglycerides(244) have gone thru he roof. She doesn't drink or smoke, is not over weight and rarely drinks a soda. She has been complaining of being dizzy and has lost a ton of hair. My mother has hashimotos hypothyroid.
Does this sound thyroid related? I'm thinking these tests were useless due to the Yaz and that she needed the free levels checked but does the TSH look high? We have stopped the Yaz and will retest in a month or two.
Thanks.

T4 is Total T4 and that's considered to be obsolete,  as is the T3 Uptake test.  You should ask for the Free T3 and Free T4, along with TSH and the 2 antibody tests, as mentioned by Red_Star.

Your daughter's symptoms, including the high cholesterol and triglycerides certainly sound hypo.

Yes, that sounds thyroid related.  Low T3 uptake is an old outdated test which has been replaced by T4. In short the doctor did two tests to tell you the same thing - T4 is elevated. :) The tests I requested when suspecting Hashimoto's thyroiditis - TSH, free T4, free T3, thyroid peroxidase antibodies (TPOAb), thyroglobulin antibodies (TgAb).
