I-hemoglobin ephezulu noma ephansi: kusho ukuthini kanye namanani ayizethenjwa

• I-hemoglobin eminyene
• I-hemoglobin emchameni

IHemoglobin, noma i-Hb, iyingxenye yamaseli abomvu futhi umsebenzi wawo omkhulu ukuhambisa umoya-mpilo ezicutshini. I-Hb iqukethe iqembu le-heme, elenziwe ngensimbi, namaketanga e-globin, angaba yi-alpha, i-beta, i-gamma noma i-delta, okuholela ezinhlotsheni eziyinhloko ze-hemoglobin, njenge:

• HbA1, eyakhiwa ngamaketanga amabili e-alpha namaketanga amabili we-beta futhi ikhona ekugxileni okuphezulu egazini;
• HbA2, okwakhiwa ngamaketanga amabili e-alpha namaketanga amabili e-delta;
• HbF, eyakhiwa ngamaketanga amabili e-alpha namaketanga amabili we-gamma futhi itholakala ekugxilweni okuphezulu ezinganeni ezisanda kuzalwa, ngokugxila kwabo kwehle ngokwentuthuko.

Ngaphezu kwalezi zinhlobo eziyinhloko, kusekhona uHb Gower I, uGower II noPortland, akhona ngesikhathi sokuphila kombungu, ngokuncipha kokugxila kwabo nokwanda kwe-HbF njengoba kusondela ukuzalwa.

I-hemoglobin eminyene

I-hemoglobin e-Glycated, ebizwa nangokuthi i-hemoglobin ye-glycosylated, isivivinyo sokuhlola esihlose ukuhlola inani le-glucose yezokwelapha egazini ezinyangeni ezintathu, elifanele kakhulu ukuxilongwa nokuqapha isifo sikashukela, kanye nokuhlola ubunzima baso.

Inani elijwayelekile le-hemoglobin ene-glycated lingu-5.7% kanti isifo sikashukela siqinisekiswa lapho inani lilingana noma lingaphezu kuka-6.5%. Funda kabanzi nge-hemoglobin ene-glycated.

I-hemoglobin emchameni

Ukuba khona kwe-hemoglobin emchameni kubizwa ngokuthi yi-hemoglobinuria futhi kuvame ukukhombisa ukutheleleka kwezinso, umalaleveva noma ubuthi bomthofu, ngokwesibonelo. Ukuhlonza i-hemoglobin emchameni kwenziwa ngokuhlolwa okulula komchamo, okubizwa nge-EAS.

Ngaphezu kwe-hemoglobin, amanani we-hematocrit akhombisa nezinguquko egazini njenge-anemia ne-leukemia. Bona ukuthi i-hematocrit iyini nokuthi ungawuqonda kanjani umphumela wayo.
