Poikilocytosis

Poikilocytosis
Examples of red blood cell types that can give rise to poikilocytosis.

Poikilocytosis is variation in the shapes of red blood cells. Poikilocytes may be oval, teardrop-shaped, sickle-shaped or irregularly contracted.

Normal red blood cells are round, flattened disks that are thinner in the middle than at the edges. A poikilocyte is an abnormally-shaped red blood cell.[1] Generally, poikilocytosis can refer to an increase in abnormal red blood cells of any shape, where they make up 10% or more of the total population of red blood cells.
