Overview

Anemia of prematurity should be differentiated from anemia due to increased red blood cell destruction, increased blood loss, and decreased red blood cell production. It should also be differentiated from other causes of normocytic normochromic anemia.

Differential Diagnosis

Anemia of prematurity should be differentiated from anemia due to increased red blood cell destruction, increased blood loss, and decreased red blood cell production. Anemia of prematurity should also be differentiated from other causes of normocytic normochromic anemia.^[1]

Increased RBC destruction

Anemia of prematurity should be differentiated from anemia due to increased red blood cell destruction:

Decrease RBC production

Anemia of prematurity should be differentiated from anemia due to decreased red blood cell production:

Increase blood loss

Anemia of prematurity should be differentiated from anemia due to increased blood loss:

Normocytic Normochromic anemia

Differentiating Anemia of prematurity from other diseases

Anemia of prematurity must be differentiated based on different laboratory findings including mean cell volume (MCV), reticulocytosis, and hemolysis.

To review the differential diagnosis of anemia, see below table.
