Before we start with the abnormal morphologies, let’s talk about normal morphology of Red Blood Cells. Normal mature RBC are biconcave, round discs that are about 6 – 8 in ...

Decreased RBC size and Hemoglobin content (MCH) and concentration (MCHC) and increased central zone of pallor for more than the third of cell diameter. Microcytic Hypochromic Anemia ...

Shape: Biconcave disc. Diameter : 7 ~ 8 μm. Central pallor occupy 1/3 rd of total cell diameter. Size : approx. same as nucleus of mature small lymphocyte.

This is a normal peripheral blood smear, you might notice very slightly anisocytosis and poikilocytosis Red cells here are normochormic and central pallor is around 1/3 of cell diameter ...
