Course provided by LabCE.

This course discusses the use of red cell indices and red cell distribution width to describe a population of red blood cells. The course provides information regarding interpretation of red cell histograms that are part of the automated cell count and correlations between indices, RDWs, and peripheral blood smear observations.

Objectives

  • Identify red blood cell (RBC) parameters reported by automated blood cell counters.
  • Relate observed RBC morphology to red cell parameters reported by automated blood cell counters.
  • Apply red cell distribution data to the RBC population observed on the peripheral smear.

Normal Erythrocytes.  Mature erythrocytes can be described as round, elastic, non-nucleated, bi-concave discs which appear pinkish to buff colored in Wright's stained smears.  EMCHP405005


Dimorphic red cell population (double red cell population),


macrocytes hetero edit


Macrocytes, pernicious anemia.  Many of the macrocytes seen in this peripheral smear are larger than the diameter of the lymphocyte nucleus, and are oval in shape. These are called megalocytes, seen in pernicious anemia. EMHCP405018.

Spherocytes.  A spherocyte is shown by the arrow.  Hereditary spherocytosis and immune hemolytic anemia are the two conditions in which an increased number of these cells are seen.EMHCP40565
