Chapter 7 - A Guide to Identifying the Cause of Anemia in a Neonate

from Section III - Erythrocyte Disorders

Summary

Diagnosing anemia in a neonate is only a first step in a process that includes: clarifying the pathology responsible for the anemia, instituting the best-known therapy (if indeed a treatment is warranted), and then evaluating whether the therapy administered was effective in alleviating the anemia. Chapters 4, 6–10 and 20 focus on the principal varieties of anemia that occur in the neonatal period. The purpose of this chapter is not to repeat material detailed there, but to provide a method for navigating the somewhat unique process of diagnosing neonatal anemia and then discovering its cause. To accomplish this purpose, the chapter is organized into two parts: (1) making the diagnosis of anemia in neonates using reference intervals appropriate for gestational and postnatal age, and (2) following an evaluative algorithm to identify the underlying cause of the anemia in a neonatal patient.
