Bite cells tuaj yeem muaj ntau dua ib "tom." Cov "tom" hauv degmacytes me dua li cov qe ntshav liab uas ploj lawm pom hauv schistocytes. Degmacytes feem ntau tshwm sim me me, ntom, thiab sib cog lus ntau dua li cov qe ntshav liab ib txwm vim yog tom.
Cov xwm txheej twg ua rau schistocytes?
Txoj Cai. Schistocytes ntawm cov ntshav peripheral smear yog cov yam ntxwv ntawm microangiopathic hemolytic anemia (MAHA). Qhov ua rau ntawm MAHA tuaj yeem nthuav tawm intravascular coagulation, thrombotic thrombocytopenic purpura, hemolytic-uremic syndrome, HELLP syndrome, malfunctioning cardiac li qub thiab lwm yam.
