Thyroid ine basa rakakosha pakugadzirisa metabolism yemuviri, kukura uye kukura. Chero kusashanda zvakanaka kwethyroid kunogona kukonzera matambudziko mazhinji ehutano. Imwe hormone yakakosha inogadzirwa nethyroid gland ndeye T4, iyo inoshandurwa mumhando dzakasiyana-siyana dzemuviri kune imwe hormone inokosha, T3.

Free T4 (f-T4) chiyero chechimiro chisina kusungwa uye chinoshanda cheT4 hormone inotenderera muropa. Kuongorora mazinga ef-T4 kwakakosha pakuongorora thyroid basa uye kuongorora chirwere cherurindi.

Kukosha kwef-T4 kuyedza:

Kuongorora f-T4 mazinga akakosha kusiyanisa hyperthyroidism (hyperthyroidism) kubva hypothyroidism (hypothyroidism). Hyperthyroidism inoratidzirwa neakakwira f-T4 mazinga, nepo hypothyroidism inoguma yakaderera f-T4 mazinga.

Mukuwedzera, f-T4 mazinga anoshandiswa kuongorora subclinical thyroid dysfunction muvarwere vanouya nezviratidzo zvisinganzwisisiki zvechirwere chetachiona. Yakajairika TSH level asi yakaderera f-T4 level inoratidza subclinical hypothyroidism, nepo yakakwira f-T4 level uye yakajairika TSH level inogona kuratidza subclinical hyperthyroidism.

Pamusoro pekuongororwa, kutarisa f-T4 mazinga kwakakosha kuti uongorore kushanda kwechirwere chetachiona. Munyaya ye hypothyroidism, murwere anotora fomu yekugadzira yeT4 hormone kuchengetedza zvakakwana thyroid hormone mazinga. Kuyera nguva dzose kwemazinga e-f-T4 kunodiwa kuti uone chiyero chakakodzera chemishonga yekugadzira T4.

Dudziro yef-T4 mhinduro dzebvunzo:

Reference ranges yef-T4 inogona kusiyana nerabhoritari uye assay inoshandiswa pakuyedza. Nekudaro, iyo yakajairika chiyero chef-T4 mazinga anowanzo pakati pe0.7 - 1.8 ng/dL.

Zvisizvo f-T4 mazinga anogona kuratidza zvakasiyana-siyana zvehutano hwehutano, kusanganisira hypothyroidism, hyperthyroidism, uye thyroid nodules. Yakakwirira f-T4 mazinga anogona kutungamirira kune zviratidzo zvakadai sokurasikirwa, kuzvidya mwoyo, uye kudengenyeka, asi kuderera kwef-T4 mazinga kunogona kutungamirira kuhuremu, kuneta, uye kuora mwoyo.

mukupedzisa:

Thyroid function inoita basa rakakosha mukuchengetedza hutano hwese uye kugara zvakanaka. Kuongorora mazinga ef-T4 kwakakosha pakuongorora thyroid basa uye kuongorora chirwere cherurindi. Kuongororwa kwef-T4 kunodiwawo kuti uone kurapa kwakakodzera kwechirwere chetachiona. Kuzivikanwa kwekutanga uye kutonga kwechirwere chethyroid kunogona kudzivirira mamwe matambudziko ehutano. Naizvozvo, zvakakosha kubvunza mutapi wako wehutano kana ukaona chero zviratidzo zvine chekuita nekusashanda zvakanaka kwethyroid.

Mukupedzisa, kuongororwa kwef-T4 chinhu chakakosha chekuongorora hutano hwethyroid uye manejimendi. Thyroid function test, kusanganisira f-T4 zviyero, inofanira kuitwa nguva dzose kuti ive nechokwadi chekushanda kwehuroro yakakwana uye hutano hwose.
