I-thyroid idlala indima ebalulekile ekulawuleni ukusetjenziswa komzimba, ukukhula kanye nentuthuko. Noma yikuphi ukungasebenzi kahle kwe-thyroid kungaholela ezinkingeni eziningi zempilo. I-hormone eyodwa ebalulekile ekhiqizwa yi-thyroid gland yi-T4, eguqulwa ezicutshini zomzimba ezahlukahlukene ibe enye i-hormone ebalulekile, i-T3.

I-T4 yamahhala (f-T4) iyisilinganiso sendlela ekhululekile nesebenzayo ye-hormone ye-T4 ejikeleza egazini. Ukuqapha amazinga e-f-T4 kubalulekile ekuhloleni ukusebenza kwe-thyroid kanye nokuxilonga isifo se-thyroid.

Ukubaluleka kokuhlolwa kwe-f-T4:

Ukuhlola amazinga e-f-T4 kubalulekile ukuze kuhlukaniswe i-hyperthyroidism (hyperthyroidism) ku-hypothyroidism (hypothyroidism). I-Hyperthyroidism ibonakala ngamazinga aphezulu e-f-T4, kanti i-hypothyroidism iholela ekwehleni kwamazinga e-f-T4.

Ngaphezu kwalokho, amazinga e-f-T4 asetshenziselwa ukuxilonga ukungasebenzi kahle kwe-thyroid okungajwayelekile ezigulini ezibonisa izimpawu ezingacacile zesifo se-thyroid. Izinga elijwayelekile le-TSH kodwa izinga eliphansi le-f-T4 libonisa i-hypothyroidism engajwayelekile, kanti izinga eliphakeme le-f-T4 kanye nezinga elijwayelekile le-TSH lingabonisa i-hyperthyroidism engajwayelekile.

Ngaphezu kokuxilongwa, ukuqapha amazinga e-f-T4 kubalulekile ukuhlola ukusebenza kahle kokwelashwa kwe-thyroid. Uma kwenzeka i-hypothyroidism, isiguli sithatha uhlobo lokwenziwa lwe-hormone ye-T4 ukuze silondoloze amazinga afanele e-hormone ye-thyroid. Ukulinganisa njalo amazinga e-f-T4 kuyadingeka ukuze kunqunywe umthamo ofanele wemithi ye-T4 yokwenziwa.

Ukuhunyushwa kwemiphumela yokuhlolwa kwe-f-T4:

Amabanga okubhekisela e-f-T4 angahluka kuye ngelabhorethri kanye nokuhlolwa okusetshenziselwa ukuhlola. Kodwa-ke, ububanzi obujwayelekile bamazinga e-f-T4 buvame ukuba phakathi kuka-0.7 - 1.8 ng/dL.

Amazinga e-f-T4 angajwayelekile angabonisa izifo ezahlukahlukene ze-thyroid, okuhlanganisa i-hypothyroidism, i-hyperthyroidism, kanye nama-nodule e-thyroid. Amazinga aphezulu e-f-T4 angaholela ezimpawini ezifana nokwehla kwesisindo, ukukhathazeka, kanye nokuthuthumela, kuyilapho amazinga e-f-T4 ehla angaholela ekukhuleni kwesisindo, ukukhathala, kanye nokucindezeleka.

Ekuphetheni:

Umsebenzi we-thyroid udlala indima ebalulekile ekugcineni impilo kanye nenhlalakahle iyonke. Ukuqapha amazinga e-f-T4 kubalulekile ekuhloleni umsebenzi we-thyroid kanye nokuxilonga isifo se-thyroid. Ukuhlolwa kwe-f-T4 kuyadingeka futhi ukuze kutholakale umthamo ofanele wokwelashwa kwesifo se-thyroid. Ukuqashelwa kusenesikhathi kanye nokuphathwa kwesifo se-thyroid kungavimbela ezinye izinkinga zempilo. Ngakho-ke, kubalulekile ukubonisana nomhlinzeki wakho wezempilo uma uhlangabezana nanoma yiziphi izimpawu ezihlobene nokungasebenzi kahle kwe-thyroid.

Ekuphetheni, ukuhlolwa kwe-f-T4 kuyisici esibalulekile sokuhlolwa nokuphathwa kwempilo ye-thyroid. Ukuhlolwa kokusebenza kwe-thyroid, okuhlanganisa nokulinganiswa kwe-f-T4, kufanele kwenziwe njalo ukuqinisekisa ukusebenza kahle kwe-thyroid kanye nempilo iyonke.
