TT4 Ikizamini

Thyroxine (T4), cyangwa 3,5,3 ', 5'-tetraiodothyronine, ni imisemburo ya tiroyide ifite uburemere bwa molekuline ingana na 777Da irekurwa mu kuzenguruka ku buntu, aho abarenga 99% bahujwe na poroteyine muri plasma kandi umubare muto cyane wubusa T4 (FT4) udahuza na proteyine muri plasma.Ibikorwa by'ingenzi bya T4 birimo gukomeza gukura no gutera imbere, guteza imbere metabolisme, gutanga ingaruka z’imitsi n’umutima n’umutima, bigira ingaruka ku mikurire y’ubwonko, kandi ni kimwe mu bigize gahunda yo kugenzura imisemburo ya hypothalamic-pituito-tiroyide, ifite uruhare mu kugenga metabolisme y’umubiri.TT4 bivuga igiteranyo cyubusa kandi gihujwe na tiroxine muri serumu.Kwipimisha TT4 bikoreshwa mubuvuzi nk'isuzuma ry'ubufasha bwo gukora nabi tiroyide, kandi kwiyongera kwayo bikunze kugaragara muri hyperthyroidism, subacute tiroyide, serum nyinshi ya tiroxine-ihuza globuline (TBG), hamwe na syndrome ya hormone ya tiroyide;kugabanuka kwayo kugaragara muri hypotherroidism, kubura tiroyide, lymphoide karande Goiter, nibindi
