FT3 ndi FT4 ndi chidule cha Chingerezi cha serum free triiodothyronine ndi serum free thyroxine, motsatana.
FT3 ndi FT4 ndizo zizindikiro zodziwika kwambiri za matenda a hyperthyroidism.
Chifukwa chakuti zomwe zili m'magazi sizimakhudzidwa ndi chithokomiro chomwe chimamanga globulin, ali ndi phindu lothandizira pofufuza matenda a hyperthyroidism ndi hypothyroidism, kuyesa kuopsa kwa matendawa, ndi kuyang'anira chithandizo chamankhwala.
Kutsimikiza kwa milingo ya seramu kapena plasma ya Triiodothyronine (T3) imadziwika ngati muyeso wofunikira pakuwunika momwe chithokomiro chimagwirira ntchito.Zotsatira zake pamagulu omwe akuwunikira zimakhala zamphamvu kuwirikiza kanayi kuposa za T4.T3 yaulere (FT3) ndi mawonekedwe osamangika komanso achilengedwe, omwe amayimira 0.2-0.4 % yokha ya T3 yonse.
Kutsimikiza kwa T3 yaulere kuli ndi mwayi wokhala wodziyimira pawokha pakusintha kwazomwe zimakhazikika komanso zomangira za mapuloteni omangira;Chifukwa chake T3 yaulere ndi chida chothandiza pakuwunika kwanthawi zonse kwachipatala pakuwunika momwe chithokomiro chilili.Miyezo yaulere ya T3 imathandizira kuzindikirika kosiyana kwa matenda a chithokomiro, ndikofunikira kusiyanitsa mitundu yosiyanasiyana ya hyperthyroidism, komanso kuzindikira odwala omwe ali ndi T3 thyrotoxicosis.
Kutsimikiza kwa milingo ya seramu kapena plasma ya Thyroxine (T4) imadziwika ngati muyeso wofunikira pakuwunika ntchito ya chithokomiro.Thyroxine (T4) ndi imodzi mwa timadzi tambiri tambiri timene timapangidwa ndi chithokomiro (enawo amatchedwa triiodothyronine, kapena T3), T4 ndi T3 amayendetsedwa ndi njira yowunikira yomwe imakhudza hypothalamus ndi pituitary gland.
T4 yaulere imayesedwa pamodzi ndi TSH pamene kukayikira kwa matenda a chithokomiro.Kutsimikiza kwa fT4 kulinso koyenera kuyang'anira mankhwala a thyrosuppressive.Kutsimikiza kwa T4 yaulere kuli ndi ubwino wodziyimira pawokha pakusintha kwazomwe zimakhalapo komanso zomangira za mapuloteni omangira;
Zomwe zili mu FT3 ndizofunika kwambiri pakuzindikiritsa kuti chithokomiro chimagwira ntchito bwino, hyperthyroid kapena hypothyroidism.Ndizovuta kwambiri pakuzindikira matenda a hyperthyroidism ndipo ndi chizindikiro cha T3 hyperthyroidism.
Kutsimikiza kwa FT4 ndi gawo lofunika kwambiri la matenda a chizolowezi ndipo angagwiritsidwe ntchito ngati njira yowunikira chithandizo cha chithokomiro.Ngati chithokomiro chikukayikiridwa, FT4 ndi TSH nthawi zambiri zimayesedwa pamodzi.
