title: Application of Flow Cytometry in the Evaluation of Primary Immunodeficiencies.
abstract: Primary immunodeficiency disorders (PIDDs) are a heterogeneous group of inherited disorders of the immune system. Currently more than 250 different PIDDs with a known genetic defect have been recognized. The diagnosis of many of these disorders is supported strongly by a wide variety of flow cytometry applications. Flow cytometry offers a rapid and sensitive tool for diagnosis and classification of PIDDs. It is applicable in the initial workup and subsequent management of several primary immunodeficiency diseases. As our understanding of the pathogenesis and management of these diseases increases, the majority of these tests can be easily established in the diagnostic laboratory. Thus, the focus of this article is on the application of flow cytometry in the diagnosis and/or evaluation of PIDDs.
