Exam T4 (manuahi a me ka huina): he aha ia a pehea e hana ai?
Anter
Ke manaʻo nei ka hōʻike T4 e loiloi i ka hana o ka thyroid ma ke ana ʻana i ka nui o ka hormone T4 a me ka T4 manuahi. Ma lalo o nā kūlana maʻamau, hoʻonāuki ka hormone TSH i ka thyroid e hana i ka T3 a me ka T4, he mau hormones ke kuleana no ke kōkua ʻana i ka metabolism, e hāʻawi ana i ka ikehu e pono ai no ka hana pololei ʻana o ke kino. ʻAneʻane hoʻopili ʻia ʻo T4 i nā protein i hiki ai ke lawe ʻia i ke kahe o ke koko i nā mea like ʻole a hiki ke hana i kāna hana.
Koi ʻia kēia hōʻike e ke kauka i nā hoʻokolohua maʻamau, akā ʻoi aku ka maikaʻi ke hōʻike ʻia ke kanaka i nā ʻōuli o hypo a i ʻole hyperthyroidism, no ka laʻana, a i ʻole ke hopena TSH i hoʻololi ʻia. E ʻike i ke ʻano o ka hōʻike TSH a me nā helu kūmole.
He aha ka huina T4 a me T4 manuahi?
Hoʻohana ʻia nā T4 manuahi a me ka huina T4 e loiloi i kāu hana thyroid, ʻo ia hoʻi, e hōʻoia inā hana ka gland i kahi maʻamau a lawa kūpono o nā homone e hāʻawi i ka ikehu no nā hana metabolic o ke kino. Ma lalo o 1% o T4 i loko o ka palapala manuahi, a ʻo ia kēia ʻano i hana metabolically, ʻo ia hoʻi, he hana kāna. ʻAʻohe hana a ka protein Pr4in-bound T4, lawe wale ʻia ia i ke kahe o ke koko i nā lālā, a inā pono, hoʻokaʻawale ʻia ia mai ka protein no ka hana.
Kūlike ka huina T4 i ka huina nui o ka hormone i hana ʻia, ke loiloi ʻia i ka nui i hoʻopili ʻia i nā protein a me ka mea e kahe manuahi ana i loko o ke koko. Eia nō naʻe, he nonspecific liʻiliʻi paha ka huina T4 āpau, no ka mea aia paha ke keakea ʻia me nā protein i hiki ke hoʻopaʻa ʻia i ka hōmona.
ʻO ka T4 manuahi, ma ka ʻaoʻao ʻē aʻe, ua kikoʻī loa ia, maʻalahi a ʻae i kahi loiloi ʻoi aku o ka thyroid, ʻoiai ke ana ʻia ka nui o ka hormone e hana ana a hana i ke kino.
Pehea e pau ai ka hōʻike
Hana ʻia ka hoʻāʻo me kahi hāpana koko a ʻaʻohe pono o ka hoʻomākaukau ma mua o ka lawe ʻana. Eia nō naʻe, inā e hoʻohana ana ke kanaka i nā lāʻau e hoʻopilikia ai i ka thyroid, pono ʻo ia e hoʻomaopopo i ke kauka no laila e noʻonoʻo ʻia kēia i ke kālailai ʻana.
Hoʻouna ʻia ka laʻana o ke koko i hōʻiliʻili ʻia i ke keʻena hoʻokolohua, kahi e hana ʻia ai nā hana T4 manuahi a me ka huina. Nā waiwai maʻamau o T4 manuahi aia ma waena 0.9 - 1.8 ng / dL, ʻoiai nā kumukūʻai maʻamau no ka huina T4 e like me ka makahiki.
| Makahiki | Nā waiwai maʻamau o ka huina T4 |
| 1st pule o ke ola | 15 µg / dL |
| A hiki i ka malama 1 | 8.2 - 16.6 µg / dL |
| Ma waena o 1 a me 12 mau mahina o ke ola | 7.2 - 15.6 µg / dL |
| Ma waena o 1 a me 5 mau makahiki | 7.3 - 15 µg / dL |
| Ma waena o 5 a me 12 mau makahiki | 6.4 - 13.3 µg / dL |
| Mai ka 12 mau makahiki | 4.5 - 12.6 µg / dL |
Hoʻohālikelike a hoʻemi ʻia paha nā waiwai T4 i hōʻike i ka hypo a i ʻole ka hyperthyroidism, ka maʻi ʻaʻai thyroid, thyroiditis, goiter a me ka wahine infertility, e laʻa me. Hoʻohui ʻia, hoʻemi ʻia nā waiwai o ka T4 manuahi i mea e hōʻike ai i ka malnutr a i ʻole ka thyroiditis o Hashimoto, no ka laʻana, he maʻi autoimmune i hōʻike ʻia e ka mumū o ka thyroid e alakaʻi ana i ka hyperthyroidism ukali ʻia e hypothyroidism.
Āhea e hana ai
Nonoi ʻia ka hōʻike T4 e ka endocrinologist i nā hanana e like me:
- Nā hopena hōʻike TSH i hoʻololi ʻia;
- Ka nāwaliwali, hoʻoliʻiliʻi metabolism a me ka māluhiluhi, kahi paha e hōʻike ana i ka hypothyroidism;
- Nervousness, hoʻonui i ka metabolism, hoʻonui i ka makemake, kahi e hōʻike ai i ka hyperthyroidism;
- Kuhi ʻia ka maʻi ʻaʻai thyroid;
- Nānā i ke kumu o ka hānau wahine ʻole.
Ma muli o ka loiloi o nā hopena hōʻike a me nā ʻōuli o ke kanaka, hiki i ka endocrinologist ke wehewehe i ka hōʻailona a me ke ʻano ʻoi loa o ka lapaʻau, a no laila normalizing pae T4. E aʻo e pili ana i nā hoʻokolohua pono ʻē aʻe e loiloi i kāu thyroid.
