Hello. An 8 years old with a red rash was asked by her dr. to do some blood tests because, he couldn't tell why she has the rash. With no prior history in thyroid issues, blood tests results showed the following:
FreeT4 0.89 ( range0.8-2.3)
Free T3 4.55 (1.8-4.6)
TSH 36.72 ( 0.3-5)
Antithyroglobulin Ab. 7 ( <15.0)
Antiperoxidase Ab. 55.3 ( <10)
What do you think ? Is she hypo ? Hashimoto?
The dr. prescribed 25 mcg Synthroid already. Any help is appreciated please.
