title: Practical approach to the investigation of neutropenia.
abstract: This article discusses the evaluation of a patient for possible neutropenia. An evaluation must include an integration of complex factors such as age- and race-related normal ranges for absolute neutrophil count, an assessment of other hematopoietic elements in blood, an investigation for possible underlying infections, an examination for splenomegaly, and an evaluation for evidence of recurrent infections or family history suggestive of a constitutional neutropenic disorder.
