Ukusetyenziswa kwenjongo

Ikhithi yokuqondakubaIyonke ye-thyroxine(I-Fluorescence I-Assunotographic Assey) yi-Fluorescence Junossographic Sunousotographic kwi-Confel Consedning yeTyroxine (i-TT4) kwi-Serum yomntu oQinisekileyo. Iindlela zokusebenza. Olu vavanyo lwenzelwe ukhathalelo lwempilo kuphela.

Isishwankathelo

I-thyroxine (i-T4) ifihlwa yi-thyroid gland kunye nobunzima bayo molekyuli ngama-777d. Iyonke i-T4 (iyonke i-T4, i-TT4) kwi-serum ngamaxesha angama-50 e-serum t3. Phakathi kwabo, i-99.9% ye-TT4 Binds kwi-serm ye-proteroxine yokubopha (i-TBP), kunye ne-t4 ye-T4 (i-T4) ingaphantsi kwe-0.05%. I-T4 kunye ne-T3 ithatha inxaxheba ekulawuleni umsebenzi we-metabolic yomzimba. Imilinganiselo ye-TT4 isetyenziselwa ukuvavanya imeko kunye nokufumanisa izifo. Ikliniki, i-TT4 ingumqondiso onokuthenjwa wokuqonda kunye nokubonakalayo kwenkqubo ye-hypernidism kunye ne-hypothyroidism.
