Papel da imunofenotipagem por citometria de fluxo no diagnóstico diferencial das pancitopenias e das linfocitoses

Abstract

The use of flow cytometry for immunophenotyping is currently an essential tool in the diagnosis of hematological abnormalities. In recent years, new equipment, antibodies, fluorochromes and computer programs have become available. As a result, a better understanding of the pathogeneses of hematological malignancies has emerged and new markers with diagnostic and prognostic relevance have been described. Here we review how this new technology may contribute to the differential diagnosis of patients with bi- or pancytopenia and of lymphocytosis. The common findings as well as the difficulties in interpreting the results obtained by flow cytometry will be discussed. The importance of the concomitant analyses by different methods is also demonstrated. Rev. Bras. Hematol. Hemoter.
