T4 bụ isi ngwaahịa nke thyroid secretion, na hypothalamic-anterior pituitary-thyroid regulatory usoro ezughị ezu Iberibe efu. Ọ na-abawanye ọnụego metabolic basal ma na-arụ ọrụ dị mkpa na mmepe nke sel anụ ahụ niile. A na-echekwa T4 na follicle thyroid na thyroglobulin ma na-ezobe ya ma hapụ ya n'okpuru iwu nke TSH. Serum Ihe karịrị 99% nke T4 na T4 dị n'ụdị njikọ na protein ndị ọzọ. Nnwale maka ngụkọta T4 na nlele ọbara nwere ike ịma ma ị nwere ọrụ thyroid na-adịghị mma.
