Ihemoglobin ephezulu okanye ephantsi: ukuba kuthetha ntoni kunye namaxabiso esalathiso

Umxholo
IHemoglobin, okanye iHb, yinxalenye yeeseli ezibomvu zegazi kunye nomsebenzi wayo ophambili kukuhambisa ioksijini kwizicwili. I-Hb iqulathe iqela le-heme, elenziwe ngentsimbi, kunye neetyin globin, ezinokuthi zibe yi-alpha, i-beta, i-gamma okanye i-delta, nto leyo ekhokelela kwezona ntlobo ziphambili ze-hemoglobin, ezinje:
- HbA1, ezenziwa ngamatyathanga amabini e-alpha kunye namatyathanga amabini e-beta kwaye ikho koxinzelelo oluphezulu egazini;
- HbA2, ezenziwa yimixokelelwane emibini ye-alpha kunye neetyathanga ezimbini ze-delta;
- HbF, ezenziwa ngamatyathanga amabini e-alpha kunye namatyathanga amabini e-gamma kwaye akhoyo koxinzelelo oluphezulu kwiintsana ezisanda kuzalwa, kunye nokuxinana kwabo kwehle ngokokuphuhliswa.
Ukongeza kwezi ntlobo ziphambili, kusekho uHb Gower I, Gower II kunye nePortland, abakhoyo ngexesha lobomi bembungu, ngokuncipha koxinzelelo lwabo kunye nokonyuka kwe-HbF xa kusondela indlela yokuzalwa.
Ihemoglobin emhlophe
I-hemoglobin eglycated, ekwabizwa ngokuba yi-glycosylated hemoglobin, luvavanyo lokuqonda isifo olujolise ekujongeni inani leswekile yegazi egazini ngeenyanga ezi-3, ilunge kakhulu ekuchongeni nasekuhloleni isifo seswekile, kunye nokuvavanya ubuzaza bayo.
Ixabiso eliqhelekileyo le-hemoglobin ene-glycated yi-5.7% kwaye isifo seswekile siqinisekiswa xa ixabiso lilingana okanye lingaphezulu kwe-6.5%. Funda ngakumbi malunga ne-hemoglobin eglycated.
IHemoglobin kumchamo
Ubukho behemoglobin kumchamo kuthiwa yihemoglobinuria kwaye ihlala ibonisa usulelo lwezintso, isifo seengcongconi okanye ityhefu yelothe, umzekelo. Ukuchongwa kwehemoglobin kumchamo kwenziwa ngovavanyo lomchamo olulula, olubizwa ngokuba yi-EAS.
Ukongeza kwi-hemoglobin, i-hematocrit values ikwabonisa utshintsho egazini njenge-anemia kunye neleukemia. Jonga ukuba yintoni ihemmatocrit kunye nendlela yokuqonda iziphumo zayo.
