In Hashimoto's thyroiditis, T4 (thyroxine) functions like crude oil or money in the bank, while T3 (triiodothyronine) serves as the fuel or cash in hand; without proper conversion of T4 to T3, the body cannot function properly even when TSH and T4 levels appear normal, which is why comprehensive testing including T3, T3 resin uptake, thyroid antibodies, and other markers is essential for accurate diagnosis and treatment.

>> Yes. I try to explain to people, you know, we have T4, we have T3. T4 is our crude oil.
T3 is our fuel.
