Umthamo weVolumu yeCorpuscular Volume (CMV): yintoni kwaye kutheni iphezulu okanye iphantsi

Umxholo

• Iinguqu ezinokwenzeka ze-VCM
• 1. Yintoni enokuba phezulu VCM
• 2. Yintoni enokuba phantsi kwe-CMV
• I-CMV kuvavanyo lwe-anemia

I-VCM, okuthetha ukuba uMndilili weCorpuscular Volume, sisalathiso esikhoyo kubalo lwegazi esibonisa ubungakanani obuqhelekileyo beeseli ezibomvu zegazi, ezibomvu iiseli zegazi. Ixabiso eliqhelekileyo le-VCM liphakathi kwe-80 kunye ne-100 fl, kwaye linokwahluka ngokwelabhoratri.

Ukwazi isixa se-CMV kubaluleke ngakumbi ukunceda ekuchongeni i-anemia kunye nokubeka iliso kwisigulana emva kokuqala unyango. Nangona kunjalo, uhlalutyo lwe-VCM kufuneka lwenziwe kunye nohlalutyo lwamanani egazi, ngakumbi i-HCM, i-RDW kunye ne-hemoglobin. Funda indlela yokutolika ubalo lwegazi.

Iinguqu ezinokwenzeka ze-VCM

Umthamo we-corpuscular volume unganyuswa okanye wehle, nganye yezi meko ziimpawu zeengxaki ezahlukeneyo zempilo:

1. Yintoni enokuba phezulu VCM

I-VCM ephezulu ibonisa ukuba iiseli ezibomvu zikhulu, kwaye ukunyuka kwexabiso le-RDW kuhlala kubonakala, imeko eyaziwa ngokuba yi-anisocytosis. Fumanisa ukuba kuthetha ntoni i-RDW kuvavanyo lwegazi.

Ixabiso elonyukayo linokubonisa i-megaloblastic anemia kunye ne-anemia eyingozi, umzekelo. Kodwa inokutshintshwa kukuxhomekeka kotywala, ukopha, i-myelodysplastic syndromes kunye ne-hypothyroidism.

2. Yintoni enokuba phantsi kwe-CMV

I-CMV esezantsi ibonisa ukuba iiseli ezibomvu zegazi ezikhoyo egazini zincinci, zibizwa ngokuba zii-microcytic. Iiseli ezibomvu zeMicrocytic zingafunyanwa kwiimeko ezininzi, ezinjenge-thalassemia encinci, i-spherocytosis yokuzalwa, i-uremia, izifo ezinganyangekiyo kwaye ngakumbi i-anemias yokunqongophala kwe-iron, ekwabizwa ngokuba yi-hypochromic microcytic anemias, njengoko nazo zine-HCM ephantsi. Qonda ukuba yintoni i-HCM.

I-CMV kuvavanyo lwe-anemia

Uxilongo lwe-anemia, ugqirha ujonga ikakhulu amaxabiso e-hemoglobin, ukongeza kwezinye ii-indices, ezinjenge-VCM kunye ne-HCM. Ukuba i-hemoglobin iphantsi, uhlobo lwe-anemia lunokuchongwa kwezi ziphumo zilandelayo:

• IVCM esezantsi kunye ne-HCM: Ithetha i-anemia ye-microcytic, enje ngokuswela i-anemia;
• I-CMV eqhelekileyo kunye ne-HCM: Kuthetha i-anemia ye-normocytic, enokuthi ibonakalise i-thalassemia;
• I-MCV ephezulu: Ithetha i-macrocytic anemia, enje nge-megaloblastic anemia, umzekelo.

Ngokusekwe kwiziphumo zobalo lwegazi, ugqirha unoku-odola ezinye iimvavanyo ezinokuqinisekisa ukubonwa kwe-anemia. Jonga ukuba zeziphi iimvavanyo eziqinisekisa i-anemia.
