Uviwo T4 (simahla kwaye iyonke): yenzelwe ntoni kwaye yenziwa njani?
Umxholo
Uvavanyo lwe-T4 lujolise ekuvavanyeni ukusebenza kwe-thyroid ngokulinganisa i-hormone iyonke i-T4 kunye ne-T4 yasimahla. Kwiimeko eziqhelekileyo, i-hormone ye-TSH ivuselela i-thyroid ukuvelisa i-T3 kunye ne-T4, eziyi-hormone ezinoxanduva lokuncedisa imetabolism, ukubonelela ngamandla afanelekileyo ekusebenzeni ngokuchanekileyo komzimba. I-T4 iphantse yadityaniswa ngokupheleleyo kwiiproteni ukuze ikwazi ukuhanjiswa egazini iye kumalungu ahlukeneyo kwaye ikwazi ukwenza umsebenzi wayo.
Olu vavanyo lunokucetyiswa ngugqirha kwiimviwo zesiqhelo, kodwa kungcono kuboniswe xa umntu eneempawu zehypo okanye i-hyperthyroidism, umzekelo, okanye xa kukho iziphumo ze-TSH. Jonga ukuba loluphi uvavanyo lwe-TSH kunye namaxabiso esalathiso.
Iyintoni i-T4 iyonke kunye ne-T4 yasimahla?
Zombini i-T4 yasimahla kunye ne-T4 iyonke isetyenziselwa ukuvavanya ukusebenza kwe-thyroid, oko kukuthi, ukuqinisekisa ukuba ingaba le ndlala ivelisa isixa esiqhelekileyo nesaneleyo samahomoni ukubonelela ngamandla ngezinto zomzimba. Ngaphantsi kwe-1% ye-T4 ikwimo yasimahla, kwaye yile fomu esebenzayo, oko kukuthi, inemisebenzi. I-T4 eboshwe ziiprotein ayinanto yakwenza, ihanjiswa kuphela kwigazi ukuya kumalungu, kwaye xa kufanelekile, yahlulwe kwiprotein yomsebenzi.
Itotali iyonke iyahambelana nenani elipheleleyo lehomoni evelisiweyo, kuvavanywa zombini isixa esidityaniswe neeproteni kunye nesimahla esijikeleza egazini. Nangona kunjalo, idreyithi iyonke ye-T4 isenokuba yinto engacacanga ncam, njengoko kusenokubakho ukuphazamiseka neeproteni ezinokubanjwa yincindi yedlala.
I-T4 yasimahla, kwelinye icala, sele ikho ngakumbi, inovakalelo kwaye ivumela uvavanyo olungcono lwe-thyroid, kuba kuphela sisixa sehomoni esisebenzayo nesisebenzayo emzimbeni esilinganisiweyo
Luqhutywa njani uviwo
Uvavanyo lwenziwa ngesampulu yegazi kwaye akukho lungiselelo luyimfuneko ngaphambi kokuba uluthathe. Nangona kunjalo, ukuba umntu usebenzisa naliphi na iyeza eliphazamisa idlala lengqula, kufuneka axelele ugqirha ukuze oku kuthathelwe ingqalelo xa kuhlolisiswa.
Isampuli yegazi eqokelelweyo ithunyelwa elabhoratri, apho idosi yasimahla kunye iyonke ye-T4 yenziwa. Amaxabiso aqhelekileyo e T4 yasimahla ziphakathi 0.9 - 1.8 ng / dL, ngelixa amaxabiso aqhelekileyo e-T4 eyohluka ngokobudala:
| Ubudala | Ixabiso eliqhelekileyo le-T4 iyonke |
| I-1 yeveki yobomi | 15 iig / dL |
| Kude kube yinyanga yokuqala | 8.2 - 16.6 µg / dL |
| Phakathi kweenyanga ezili-1 ukuya kwezi-12 zobomi | 7.2 - 15.6 µg / dL |
| Phakathi kweminyaka eyi-1 kunye ne-5 | 7.3 - 15 µg / dL |
| Phakathi kweminyaka emi-5 neli-12 | 6.4 - 13.3 µg / dL |
| Ukususela kwiminyaka eli-12 ubudala | 4.5 - 12.6 µg / dL |
Ukuphakanyiswa okanye ukwehla kwamaxabiso e-T4 kunokubonisa uhanahko okanye ihypherthyroidism, umhlaza wedlala lengqula, i-thyroiditis, i-goiter nokungachumi kwabasetyhini, umzekelo. Ukongeza, ukwehla kwamaxabiso e-T4 yasimahla kunokubonisa ukungondleki okanye isifo sikaHashimoto's thyroiditis, umzekelo, esisifo sokuzimela komzimba esibonisa ukudumba kwe-thyroid okukhokelela kwi-hyperthyroidism elandelwa yi-hypothyroidism.
Ukwenza nini
Uviwo lwe-T4 luhlala lucelwa yi-endocrinologist kwiimeko ezinje:
- Iziphumo zokutshintsha kweTSH;
- Ubuthathaka, ukwehla kwemetabolism kunye nokudinwa, ezinokubonakalisa i-hypothyroidism;
- Uvalo, ukwanda kwemetabolism, ukutya okungaphezulu, okunokubonisa ihypythyroidism;
- Umhlaza womhlaza we-thyroid;
- Uphando kwisizathu sokungachumi kwabasetyhini.
Ngokusekwe kuvavanyo lweziphumo zovavanyo kunye neempawu zomntu, i-endocrinologist inokuchaza isifo kunye nohlobo olulungileyo lonyango, ngaloo ndlela kuqheleke amanqanaba e-T4. Funda ngezinye iimvavanyo ezibalulekileyo ukuvavanya i-thyroid yakho.
