Introduction: Dengue is an infectious disease common in Brazil and particularly in the city of Uberaba. The disease manifests itself with a broad spectrum of symptoms that lead to changes in blood count parameters. In our study, we studied frequency of changes in red, white and platelets series in patients with dengue in Uberaba (Minas Gerais State) comparing 2005-2006 and 2009-2010 years. Material and Methods: We analyzed blood counts of patients treated at a private laboratory and an Emergency Unit of Uberaba that had positive serology test (IgM) for dengue. Results: In the biennium of 2005-2006 and in 2009-2010 1,061 and 208 blood tests respectively, were selected for inclusion in the study. Leukopenia, lymphopenia, monocytosis and thrombocytopenia were the most frequently encountered changes. Discussion and Conclusions: These changes presented as a predictor of the disease diagnosis in cases where it would be difficult or impossible to make serologic testing to detect it.
