WebErythrocytes, or red blood cells ( RBCs ), are the most common blood cells. Normal RBCs have a biconcave shape and contain hemoglobin but no nucleus or organelles. Dysmorphic RBCs (e.g., sickle cells, target cells) have an altered form and are often a sign of an underlying condition. Hemoglobin ( Hb) is composed of heme and globin subunits and ...

WebThe following terms are used in describing the morphology of RBC's, as seen on a standard peripheral blood smear: Acanthocyte. Cell with irregular, long, asymmetrical projections; sporadically seen with severe liver disease or post-splenectomy; seen with rare disorder of abetalipoproteinemia. Anisocytosis.
WebSchistocytes. The arrows point to schistocytes which are fragmented red blood cells. Also called schizocytes, these cells result from shearing, tearing, or fragmenting.
