Zvese zvaunoda kuziva nezve thyroxine (T4) test!

Wakambonzwa nezve thyroid gland here? Pamwe chiremba wako akakukumbira kuti uite bvunzo inonzi T4. Saka, iyi T4 chii? Nei bvunzo iyi ichiitwa? Pamwe une mibvunzo yakaita seiyi. Nhasi, tichataura nezve bvunzo iyi yeT4 nenzira iri nyore yaunogona kunzwisisa.

Chii chinonzi bvunzo yeT4 (thyroxine)?

Zvichitaurwa zviri nyore, bvunzo yeT4 (thyroxine) ibvunzo yeropa inokosha inoongorora kuti thyroid gland yako iri kushanda zvakanaka sei. Inogonawo kubatsira kuona zvirwere zvine chekuita nethyroid.

Fungidzira, thyroid gland igland diki rakaita seshavishavi riri pamberi pemutsipa wako, pamusoro pebhonzo rako. Iro chikamu chehurongwa hwe endocrine yemuviri wedu. Ndiro gland rinogadzira mahormone ethyroid roaburitsa muropa. Mahormone aya anobva afamba nemuropa okanganisa nhengo dzakasiyana dzemuviri wedu.

Thyroxine, inozivikanwawo seT4 , ndiyo hormone yakawanda inoburitswa negland rako re thyroid. Kana huwandu hweT4 muropa rako hwakakwira kana kuti hwakaderera, zvinogona kuva chiratidzo chechirwere che thyroid.

Vanachiremba vanoongorora huwandu hweT4 nekutora tsananguro yeropa. Iyi thyroxine (T4) inouya mumhando mbiri:

• Bound T4: Izvi zvinobatanidzwa nemapuroteni, saka hazvigone kupinda nyore nyore munyama yemuviri.
• T4 Yemahara: Iyi ndiyo T4 "yemahara" inopinda munyama dzemuviri uye inoita basa rayo.

Saka, kune bvunzo dzakawanda dzinoyera mazinga eT4. Kuongororwa kweropa kunoyera T4 yakasununguka uye T4 yakasungwa kunonzi bvunzo yeT4 yakazara . Dzimwe bvunzo dzeropa dzinoyera T4 yakasununguka chete. Kutaura zvazviri, vanachiremba vanowanzo shandisa bvunzo yeT4 yakasununguka kuti vaongorore mashandiro ethyroid nekuti ndiyo chaiyo kupfuura bvunzo yeT4 yakazara.

Chiremba wako angangoitawo bvunzo yeTSH (Thyroid-Stimulating Hormone) pamwe chete nebvunzo yako yeT4. TSH ihormone inogadzirwa nepituitary gland yako. Iyi TSH inokurudzira thyroid gland yako kuti igadzire mahormone eT4 neT3 (triiodothyronine) .

Kutaura zvazviri, nzira yakanakisisa yekuongorora mashandiro ethyroid ndeyekuongorora TSH. Kana zvikasanganiswa neTSH test, bvunzo dzeT4 dzinogona kupa mufananidzo wakanyatsojeka wekushanda kwethyroid. Zvingasava zvakakosha kuyera mazinga eT4 mune zvese zvirwere zvethyroid.

Kune mamwe mazita akati wandei ebvunzo yeT4:

• Thyroxine yemahara
• Huwandu hwese hweT4
• Chidzitiro cheThyroxine
• Kuwanda kweT4 yemahara
• Nhamba yeT4 yemahara (FTI)

Chii chinonzi thyroxine (T4) uye chii chinoita kuti ishande?

Thyroxine (T4), inozivikanwawo se tetraiodothyronine , ndiyo homoni huru inoburitswa muropa negland rako re thyroid. Gland re thyroid rinoburitsawo huwandu hushoma hwehomoni inonzi triiodothyronine (T3) . Nekuti T4 neT3 zvinoshanda pamwe chete, ese ari maviri anowanzonzi "mahormone e thyroid."

Zvino, tarisai, mahormone makemikari anobatanidza mabasa akasiyana-siyana mumiviri yedu. Anotakura mashoko kuburikidza neropa kuenda kunhengo dzedu, tsandanyama, nedzimwe nhengo dzemuviri. Zviratidzo izvi zvinoudza miviri yedu zvekuita uye nguva yekuzviita.

T4 inoburitswa negland rako re thyroid haishande , zvichireva kuti haikanganisi zvakananga masero emuviri wako. Zvisinei, chiropa chako neitsvo zvinoshandura thyroxine yakawanda kuita triiodothyronine (T3) , hormone inoshanda inokanganisa masero emuviri wako.

Pamwe chete, T4 neT3 zvinodzora mabasa akakosha mumuviri wedu. Heano mimwe mienzaniso:

• Mwero wekuchinja kwemuviri: Uyu ndiwo mwero wekushandurwa kwechikafu chaunodya kuita simba.
• Kushanda kwemoyo uye kugaya chikafu.
• Kudzora tsandanyama.
• Kukura kwehuropi.
• Kugadziriswa kwemapfupa.

Thyroxine yakagadzirwa

Vanachiremba vanopa mushonga we thyroxine unonzi levothyroxine kurapa hypothyroidism , chirwere chinoita kuti thyroid gland isashande zvakanaka. Unogonawo kuupihwa pamwe chete nekuvhiyiwa uye mamwe marapirwo emamwe marudzi ekenza yethyroid.

Sei ndichifanira kuongororwa neT4 (thyroxine)?

Vanachiremba vanoshandisa bvunzo dzeT4 kuti vaone kuti thyroid yako iri kushanda zvakanaka sei. Heano mamwe mazvikonzero angakonzera kuti chiremba wako akuudze bvunzo dzeT4 (pamwe neTSH test):

• Kana uine mhedzisiro yeongororo ye thyroid-stimulating hormone (TSH) isina kujairika, nyatsoongorora.
