Anisopoikilocytosis is a medical condition illustrated by a variance in size (anisocytosis) and shape (poikilocytosis) of a red blood cell. The underlying cause can be attributed to various anemias, most often; beta thalassemia major, a form of microcytic anemia.
What does mild Anisopoikilocytosis mean?
Results from a blood smear can also find mild anisopoikilocytosis. This means that the amount of red blood cells showing varying sizes and shapes is more moderate. What are the causes? Anisopoikilocytosis means having both anisocytosis and poikilocytosis.
What is anisocytosis?
Anisocytosis is the medical term for having red blood cells (RBCs) that are unequal in size. Normally, a person’s RBCs should all be roughly the same size.
What does poikilocytosis mean on a blood smear?
Poikilocytosis means that there are red blood cells of varying shapes on your blood smear. Results from a blood smear can also find mild anisopoikilocytosis. This means that the amount of red blood cells showing varying sizes and shapes is more moderate. What are the causes? Anisopoikilocytosis means having both anisocytosis and poikilocytosis.
How is Anisopoikilocytosis diagnosed?
Your doctor can diagnose anisopoikilocytosis using a peripheral blood smear. For this test, a small drop of your blood is placed on a glass microscope slide and treated with a stain. The shape and size of the blood cells present on the slide can then be analyzed. A peripheral blood smear is often performed along with a complete blood count (CBC).

Anisocytosis is the medical term for having red blood cells (RBCs) that are unequal in size. Normally, a person's RBCs should all be roughly the same size. Anisocytosis is usually caused by another medical condition called anemia. It may also be caused other blood diseases or by certain drugs used to treat cancer.
How is anisocytosis treated?
Anisocytosis is often related to anemia, and anemia is typically caused by iron or vitamin deficiency. The usual treatment for iron deficiency is taking iron supplements and changing the diet to increase iron levels through iron-rich foods. The most common supplement is ferrous sulfate, which is taken as a tablet.
