Abstract
Current retrospective analysis describes the laboratorial profile of patients hypothetically diagnosed with dengue at a First-Aid Health Unit in Recife, Pernambuco State, Brazil. Results of hemograms were assessed by counting platelets and transaminase dosages, in the first half of 2012. Further, 394 patients (252 females or 64% and 142 males or 34%) were listed, mostly during March and April. Hemograms with platelet counting was undertaken with 210 patients (53.3%) and hemogram plus transaminases dosages with 184 patients (46.7%). Thrombocytopenia, neutropenia and atypical lymphocytes occurred in both genders. Hematocrits were highest in males and transaminases were more altered in females. Patients attended at the health unit with clinical symptoms of classical dengue had a laboratory profile of non-specific exams which is a feature of infection by the dengue virus. Diagnosis could not be confirmed and the need of a fast test in the health unit services was mandatory. The above avoids dengue cases not being notified and treated or overestimated.
Highlights
Dengue, a public health problem worldwide (BHATT et al, 2013), is a virus-caused disease, with Aedes aegypti as its main vector (LIMKITTIKUL et al, 2014; FERNANDES et al, 2014) and with four serum types known (DENV 1-4)

Dengue cases during the last decades have risen in all countries and between 50 and 100 million of infections by the dengue virus occur every year in some 125 countries (WHO, 2013; PAPA et al, 2015)
Summary
A public health problem worldwide (BHATT et al, 2013), is a virus-caused disease, with Aedes aegypti as its main vector (LIMKITTIKUL et al, 2014; FERNANDES et al, 2014) and with four serum types known (DENV 1-4). Dengue cases during the last decades have risen in all countries and between 50 and 100 million of infections by the dengue virus occur every year in some 125 countries (WHO, 2013; PAPA et al, 2015). Endemic regions comprise the American continent, Southeast Asia. The dengue epidemiology has greatly modified during the last score of years and global distribution expanded to other geographical areas. Transmission intensity and the seriousness of infections have increased in regions in which it was already endemic (WILSON, CHEN, 2014). Demographic and social changes, such as population growth, urbanization and modern transport have contributed towards an increase in the occurrence and geographical
