Ntiv nplhaib sideroblasts yog erythroblasts nrog hlau-loaded mitochondria pom los ntawm Prussian xiav staining (Perls 'cov tshuaj tiv thaiv) raws li perinuclear nplhaib ntawm xiav granules (Daim duab 1D thiab 2C).
Ib yam li ntawd, nws raug nug, dab tsi yog ringed sideroblasts txhais li cas?
Sideroblastic ntshav tsis txaus. Tsuas yog qhov pom ntawm nplhaib (los yog nplhaib ) sideroblasts yam ntxwv sideroblastic ntshav tsis txaus.
