The older term of myelophthisic anemia includes anemias that are associated with bone marrow fibrosis and have very different causes, such as infiltration by epithelial or lymphoid tumor cells, but also bone marrow fibrosis after irradiation. This percentage increases in all types of anemia and can be as high as 10% of the total RBCs: infectious anemias, cancer and leukaemia, thalassemias, etc. Hypersegmented neutrophils and macro-ovalocytes strongly suggest megaloblastic anemia. Common causes of abnormal red blood cells include: Drepanocytes (sickle cells): sickle cell disease Spherocytes (cup shaped): autoimmune disorders, transfusion reactions, diseases of. The cell distortion needed to navigate the slit may become permanent, resulting in a tear-drop cell. The common types are: Poikilocytosis can be diagnosed using a blood-smear test. Hopefully some other members will respond and share from personal experience. Read Responses (1) Follow. Numerous techniques have been employed to deconstruct the heterogeneity observed in normal and diseased cellular populations, including single cell RNA sequencing, in situ hybridization, and flow cytometry. The term poikilocytosis refers to a condition where 10% or more of the red blood cells are abnormally shaped due to other medical conditions.
