Thyroid levels??

Kayla

I got my results back today.

My TSH is 0.436 and normal range is 0.450-4.500 (which is low)

T4, free was 1.62 and range was 0.82-1.77

Thyroxine(T4)- 10.5 and range was 4.5-12

T3 uptake-28 and range was 24-39

Free thyroxine index was 2.9 and range is 1.3-4.9

I’m only concerned because she said everything was normal but my TSH was low?
