• Yini i-reverse T3?

Ukuhlolwa kwe-T3 kucelwa ngudokotela ngemuva kokushintsha imiphumela ye-TSH noma ye-hormone T4 noma lapho umuntu enezimpawu nezimpawu ze-hyperthyroidism, njengokwethuka, ukwehla kwesisindo, ukucasula nokucanuzela kwenhliziyo, isibonelo.

Ihomoni i-TSH ibhekele ukukhuthaza ukukhiqizwa kwe-T4, ikakhulukazi, ehlanganiswa nesibindi ukuze inikeze ifomu layo elisebenza kakhulu, i-T3. Yize iningi le-T3 lisuselwa ku-T4, indlala yegilo nayo ikhiqiza le hormone, kodwa ngamanani amancane.

Akudingekile ukuzila ukudla ukwenza isivivinyo, noma kunjalo, eminye imishanguzo ingaphazamisa imiphumela yokuhlolwa, njengezidakamizwa ze-thyroid kanye nezindlela zokuvimbela inzalo, isibonelo. Ngakho-ke, kubalulekile ukuxhumana nodokotela ukuze kunikezwe isiqondiso maqondana nokumiswa okuphephile komuthi ukwenza isivivinyo.

Yenzelwe ini

Ukuhlolwa kwe-T3 kuyacelwa lapho imiphumela yokuhlolwa kwe-TSH ne-T4 ishintshwa noma lapho umuntu enezimpawu ze-hyperthyroidism. Ngenxa yokuthi i-hormone evame ukutholakala ekugxilweni kwegazi okuphansi, umthamo we-T3 kuphela awusetshenziswa kabanzi ukuhlola ukusebenza kwe-thyroid, futhi uvame ukucelwa lapho kunesiqinisekiso sokutholakala kwesifo se-thyroid noma ndawonye ne-TSH ne-T4. Yazi ezinye izivivinyo ezihlola indlala yegilo.

Ngokungeziwe ekusizeni ukusiza ekutholeni i-hyperthyroidism, ukuhlolwa kwe-T3 kungabuye kuyalwe ukusiza ukukhomba imbangela ye-hyperthyroidism, njengesifo se-Graves, ngokwesibonelo, futhi kuvame uku-oda kanye nokukalwa kwama-autoantibodies wegilo.

Ukuhlolwa kwenziwa ngesampula segazi esithunyelwe elebhu, lapho kunqunywa khona inani lokutholakala kwe-T3 kanye ne-T3 yamahhala, okulingana kuphela no-0.3% we-T3 ephelele, ngaleyo ndlela itholakale kakhulu kwifomu yayo ehlanganisiwe. Inani eliyisithenjwa le- Ingqikithi ye-T3 é phakathi kuka-80 no-180 ng / dL futhi ka I-T3 yamahhala iphakathi kuka-2.5 - 4.0 ng / dL, zingahluka ngokuya kwelabhorethri.

Uwuqonda kanjani umphumela

Amanani we-T3 ayahluka ngokuya ngempilo yomuntu, futhi angakhuphuka, anciphiswe noma ajwayelekile:

• Ukuphakama kwe-T3: Imvamisa iqinisekisa ukuxilongwa kwe-hyperthyroidism, ekhombisa isifo se-Graves, ikakhulukazi;
• T3 okuphansi: Kungakhombisa uHashimoto's thyroiditis, neonatal hypothyroidism noma i-hypothyroidism yesibili, edinga ukuhlolwa okwengeziwe ukuqinisekisa ukuxilongwa.

Imiphumela yokuhlolwa kwe-T3, kanye neye-T4 ne-TSH, ikhombisa kuphela ukuthi kukhona ushintsho oluthile ekukhiqizeni ama-hormone yi-thyroid, futhi akunakwenzeka ukuthola ukuthi yini imbangela yalokhu kungasebenzi. Ngakho-ke, udokotela angacela ukuhlolwa okuningiliziwe ukuthola imbangela ye-hypo noma i-hyperthyroidism, efana nokubalwa kwegazi, ukuhlolwa komzimba nokuhlolwa kwe-imaging.

Yini i-reverse T3?

I-Reverse T3 iyindlela engasebenzi yehomoni etholakala ekuguqulweni kwe-T4. Umthamo we-reverse T3 awucelwa kakhulu, ukhonjiswa kuphela ezigulini ezinezifo ezinzima ezibandakanya i-thyroid, ngamazinga ancishisiwe we-T3 ne-T4, kodwa amazinga aphezulu we-reverse T3 ayatholakala. Ngaphezu kwalokho, i-reverse T3 ingaphakanyiswa ezimeni zokuxineka okungapheli, ukutheleleka ngegciwane le-HIV nokwehluleka kwezinso.

Inani eliyisithenjwa le-reverse T3 ye- izinsana ziphakathi kuka-600 no-2500 ng / mL futhi kusukela osukwini lwe-7 lokuphila, phakathi kuka-90 no-350 ng / mL, engahluka phakathi kwamalabhorethri.
