Hi Doctor,
I would like to clarify on newborn
Thyroid levels. It's a 13 day baby now.
3rd day:
TSH - 22 ( didn't check T3, T4 levels).
Started on Elyroxyn ( Thyroxin 25 mcg) daily.
13th day:
Rechecked the levels. ( Attached this report).
TSH - 0.88
Free T3 - 4.14
Free T4 - 2.01
Need help. How can TSH levels drastically change from 22 to 0.88 within 10 days of hormone replacement Eltroxin medication?.
We have a review of these latest test results with the doctor next Tuesday. Should we still continue the medicine?. Worried if it leads to hyperthyroidism. Or is it normal for TSH level to drastically reduce after starting the medicine?. Thanks.
