Idlala lengqula lidlala indima ebalulekileyo ekulawuleni inkqubo yemetabolism, ukukhula nophuhliso lomzimba.Nakuphi na ukungasebenzi kakuhle kwedlala lengqula kunokukhokelela kwinkitha yeengxaki zempilo.Enye ihomoni ebalulekileyo eveliswa lidlala lengqula yi-T4, eguqulwa kwizicubu ezahlukeneyo zomzimba iye kwenye ihomoni ebalulekileyo, i-T3.

I-T4 yamahhala (f-T4) ngumlinganiselo wefom engabonakaliyo kunye nesebenzayo ye-hormone ye-T4 ejikeleza egazini.Ukubeka iliso kumanqanaba e-f-T4 kubalulekile ekuhloleni umsebenzi we-thyroid kunye nokufumanisa isifo se-thyroid.

Ukubaluleka kovavanyo lwe-f-T4:

Ukuvavanya amanqanaba e-f-T4 kubalulekile ukwahlula i-hyperthyroidism (hyperthyroidism) kwi-hypothyroidism (hypothyroidism).I-Hyperthyroidism ibonakala ngamanqanaba aphezulu e-f-T4, ngelixa i-hypothyroidism iphumela ekunciphiseni amanqanaba e-f-T4.

Ukongezelela, amanqanaba e-F-T4 asetyenziselwa ukuxilonga i-subclinical thyroid dysfunction kwizigulane ezibonisa iimpawu ezingacacanga zesifo se-thyroid.Izinga eliqhelekileyo le-TSH kodwa i-f-T4 ephantsi ibonisa i-subclinical hypothyroidism, ngelixa i-f-T4 ephakamileyo kunye ne-TSH eqhelekileyo ingabonisa i-subclinical hyperthyroidism.

Ukongeza kwi-diagnostic, ukubeka iliso kumanqanaba e-F-T4 kubalulekile ukuvavanya ukusebenza konyango lwe-thyroid.Kwimeko ye-hypothyroidism, isigulane sithatha ifom ye-synthetic ye-hormone ye-T4 ukugcina amanqanaba aphezulu e-hormone ye-thyroid.Ukulinganisa rhoqo amanqanaba e-f-T4 kuyimfuneko ukumisela umthamo ofanelekileyo wamachiza e-synthetic T4.

Ukutolikwa kweziphumo zovavanyo lwe-f-T4:

Uluhlu lwezalathiso lwe-f-T4 lunokwahluka ngokwelabhoratri kunye novavanyo olusetyenziselwa uvavanyo.Nangona kunjalo, uluhlu oluqhelekileyo lwamanqanaba e-f-T4 luhlala luphakathi kwe-0.7 - 1.8 ng / dL.

Amanqanaba e-F-T4 angaqhelekanga angabonisa iintlobo ezahlukeneyo zeengxaki ze-thyroid, kuquka i-hypothyroidism, i-hyperthyroidism, kunye ne-thyroid nodules.Amanqanaba aphakamileyo e-f-T4 angakhokelela kwiimpawu ezifana nokulahlekelwa kwesisindo, ukuxhalaba, kunye nokuthuthumela, ngelixa ukunciphisa amanqanaba e-f-T4 kunokukhokelela ekuzuzeni ubunzima, ukukhathala kunye nokudandatheka.

ukuququmbela:

Umsebenzi we-Thyroid udlala indima ebalulekileyo ekugcineni impilo kunye nokuphila kakuhle.Ukubeka iliso kumanqanaba e-f-T4 kubalulekile ekuhloleni umsebenzi we-thyroid kunye nokufumanisa isifo se-thyroid.Uvavanyo lwe-f-T4 lukwayimfuneko ukumisela idosi efanelekileyo yonyango kwisifo se-thyroid.Ukuqatshelwa kwangaphambili kunye nokulawulwa kwesifo se-thyroid kunokuthintela ezinye iingxaki zempilo.Ke ngoko, kubalulekile ukudibana nomboneleli wakho wezempilo ukuba ufumana naziphi na iimpawu ezinxulumene nokungasebenzi kakuhle kwe-thyroid.

Ukuqukumbela, uvavanyo lwe-f-T4 luyinkalo ebalulekileyo yovavanyo lwempilo ye-thyroid kunye nolawulo.Uvavanyo lomsebenzi we-thyroid, kubandakanywa imilinganiselo ye-f-T4, kufuneka yenziwe rhoqo ukuze kuqinisekiswe ukusebenza kakuhle kwe-thyroid kunye nempilo yonke.
