I-average Corpuscular Volume (CMV): iyini nokuthi kungani iphakeme noma iphansi

• Izinguquko ezingenzeka ze-VCM
• 1. Yini engaba yi-VCM ephezulu
• 2. Yini engaba yi-CMV ephansi
• I-CMV ekutholeni i-anemia

I-VCM, okusho ukuthi i-Average Corpuscular Volume, iyinkomba ekhona esibalweni segazi ekhombisa usayizi omaphakathi wamaseli abomvu egazi, angamaseli abomvu egazi. Inani elijwayelekile le-VCM liphakathi kuka-80 no-100 fl, futhi lingahluka ngokuya nge-laboratory.

Ukwazi inani le-CMV kubaluleke kakhulu ukusiza ukuxilonga i-anemia nokuqapha isiguli ngemuva kokuqala ukwelashwa. Kodwa-ke, ukuhlaziywa kwe-VCM kufanele kwenziwe kanye nokuhlaziywa kwesibalo sonke segazi, ikakhulukazi i-HCM, i-RDW ne-hemoglobin. Funda ukuthi ungasihumusha kanjani isibalo segazi.

Izinguquko ezingenzeka ze-VCM

Umthamo we-corpuscular average ungakhuphuka noma wehle, ngasinye salezi zimo sinezimpawu zezinkinga ezahlukahlukene zezempilo:

1. Yini engaba yi-VCM ephezulu

I-VCM ephezulu ikhombisa ukuthi amaseli abomvu makhulu, futhi inani elinyukayo le-RDW livame ukubonwa, isimo esaziwa nge-anisocytosis. Thola ukuthi kusho ukuthini i-RDW ekuhlolweni kwegazi.

Inani elikhuphukile lingakhombisa i-megaloblastic anemia kanye ne-anemia eyingozi, ngokwesibonelo. Kepha kungaguqulwa ekuncikeni kotshwala, ukopha, i-myelodysplastic syndromes ne-hypothyroidism.

2. Yini engaba yi-CMV ephansi

I-CMV ephansi ikhombisa ukuthi amangqamuzana abomvu egazi akhona egazini mancane, abizwa ngokuthi yi-microcytic. Amaseli abomvu we-Microcytic angatholakala ezimweni eziningana, njenge-thalassemia encane, i-congenital spherocytosis, i-uremia, izifo ezingalapheki futhi ikakhulukazi i-anemia yokushoda kwe-iron, eyaziwa nangokuthi yi-hypochromic microcytic anemias, njengoba nayo ine-HCM ephansi. Qonda ukuthi yini i-HCM.

I-CMV ekutholeni i-anemia

Ekuhlolweni kwe-laboratory kwe-anemia, udokotela uhlola kakhulu amanani we-hemoglobin, ngaphezu kwamanye ama-indices, njenge-VCM ne-HCM. Uma i-hemoglobin iphansi, uhlobo lwe-anemia lungabonakala emiphumeleni elandelayo:

• I-VCM ephansi ne-HCM: Kusho i-anemia encane, njengokushoda kwe-iron anemia;
• I-CMV ejwayelekile ne-HCM: Kusho ukuthi i-normocytic anemia, engahle ikhombise i-thalassemia;
• I-MCV ephezulu: Kusho i-macrocytic anemia, efana ne-megaloblastic anemia, isibonelo.

Ngokuya ngomphumela wesibalo segazi, udokotela anga-oda ezinye izivivinyo ezingaqinisekisa ukutholakala kwe-anemia. Bona ukuthi yikuphi ukuhlolwa okuqinisekisa i-anemia.
