1. Dab tsi tuaj yeem ua tau siab VCM

Lub siab VCM qhia tau hais tias cov qe ntshav liab yog loj, thiab nce tus nqi ntawm RDW feem ntau pom, qhov xwm txheej hu ua anisocytosis. Tshawb xyuas seb RDW txhais li cas hauv kev kuaj ntshav.

Xws li nce rau tus nqi yuav yog kev tiv thaiv megaloblastic anemia thiab pernicious anemia, piv txwv. Tab sis nws kuj tseem tuaj yeem hloov kho cawv hauv kev quav cawv, hemorrhages, myelodysplastic syndromes thiab hypothyroidism.

2. Dab tsi tuaj yeem ua qis CMV

Cov ntshav liab me me tuaj yeem pom nyob rau ntau lub sijhawm, xws li mob thalassemia me, kab mob txha nqaj qaum, mob ntshav txha nqaj qaum, mob ntshav qab zib thiab mob ntshav tsis muaj ntshav ntau, uas paub tias yog hypochromic microcytic anemias, vim lawv kuj muaj HCM tsawg.

• Tsawg VCM thiab HCM: Nws txhais tau hais tias microcytic anemia, xws li kev siv hlau tsis muaj zog;
• Li qub CMV thiab HCM: Nws txhais tau hais tias normocytic anemia, uas yuav yog qhov qhia tau ntawm thalassemia;
• Siab MCV: Nws txhais tau tias macrocytic anemia, xws li megaloblastic anemia, piv txwv.

Raws li cov txiaj ntsig ntawm kev suav cov ntshav, tus kws kho mob tuaj yeem xaj lwm yam kev kuaj mob uas tuaj yeem paub tseeb txog kev kuaj ntshav ntawm tus mob. Saib cov kev kuaj ntshav twg uas kuaj pom muaj ntshav.
