Neonatal anemia is a condition with a diverse etiologic spectrum.Therefore, in order to form a focused differential diagnosis, it is important for the caregiver to have some knowledge of the more common causes of low hemoglobin and hematocrit concentrations in the neonate. Proper history taking, physical examination, and interpretation of diagnostic tests can narrow this focus and aid in establishing an accurate diagnosis and in directing the appropriate therapeutic interventions.
