Wetin na T4 (tayroksin) tɛst?

Fɔ tɔk am simpul wan, T4 (tayroksin) tɛst na impɔtant blɔd tɛst we de chɛk aw yu tayroyd gland de wok fayn. I kin ɛp bak fɔ no di sik dɛn we gɛt fɔ du wit tayroyd.

Imajin, di tayroyd gland na smɔl gland we tan lɛk bɔtaflay we de bifo yu nɛk, jɔs ɔp yu kɔlabɔn. Na pat pan wi bɔdi in ɛndokrin sistɛm . Na di gland we de mek tayroyd ɔmon ɛn pul dɛn na di blɔd. Dɔn dɛn ɔmon ya kin travul tru di blɔd ɛn afɛkt difrɛn pat dɛn na wi bɔdi.

Tayroksin, we dɛn kin kɔl bak T4 , na di ɔmon we bɔku pas ɔl we yu tayroyd gland kin pul. If di T4 we de na yu blɔd bɔku ɔ smɔl, i kin bi sayn fɔ tayroyd sik.

Dɔktɔ dɛn kin tɛst di T4 lɛvɛl bay we dɛn tek blɔd sɛmpul. Dis tayroksin (T4) de kam insay tu kayn we dɛn:
