Causes of microcytic erythrocytosis

A high RBC count combined with a low mean volume is seen in:

1. Thalassemia minor, either alpha or beta
2. Polycythemia vera with iron deficiency
3. Secondary polycythemia (hypoxia) with incidental iron deficiency.

Differentiating thalassemia minor from polycythemia vera:

The RBC size distribution curves reliably distinguish between thalassemia minor and polycythemia with iron deficiency.

RDW is elevated in iron deficiency. It is normal in thalassemia minor.

That's all!
