Abstract

Multiparameter flow cytometry (MFC) is a highly sensitive, fast and specific diagnostic technology with a wide range of applicability in hematology. Although well-established eight-color immunophenotyping panels are already available, most Brazilian clinical laboratories are equipped with four-color flow cytometer facilities. Based on this fact, the Brazilian Group of Flow Cytometry (Grupo Brasileiro de Citometria de Fluxo, GBCFLUX) for standardization of clinical flow cytometry has proposed an antibody panel designed to allow precise diagnosis and characterization of acute leukemia (AL) within resource-restricted areas. Morphological analysis of bone marrow smears, together with the screening panel, is mandatory for the primary identification of AL. The disease-oriented panels proposed here are divided into three levels of recommendations (mandatory, recommendable and optional) in order to provide an accurate final diagnosis, as well as allow some degree of flexibility based on available local resources and patient-specific needs. The proposed panels will be subsequently validated in an inter-laboratory study to evaluate its effectiveness on the diagnosis and classification of AL. © 2014 Clinical Cytometry Society.
