“…The patient was diagnosed with pseudothrombocytopenia (an in vitro error) and was reallocated to the group with normal platelet counts. Pseudothrombocytopenia has been reported to occur in as many as 17% of patients who visit hematology units to seek a diagnosis for their thrombocytopenia [31][32][33][34][35][36] . We are planning a new study in rural areas of Brazil that are endemic for schistosomiasis to assess the frequency of pseudothrombocytopenia.…”

“…It is believed that the decrease of thrombocytes could be related to immune mediate response produced for EDTA anticoagulant and intensified by lower temperatures. In those cases, activation and posterior thrombocyte aggregation occurs, leading to pseudo thrombocytopenia (Dusse et al 2004). In some cases, leaving the sample at room temperatures before the performance of the analysis minimizes these differences (Mylonakis et al 2008, Wills & Wardrop 2008.…”

“…12 Entretanto, as maiores causas de erros nas contagens de plaquetas podem resultar de características da amostra de sangue como, por exemplo, contagens falsamente baixas de plaquetas em consequência à coagulação parcial da amostra, à agregação plaquetária devido a uma coleta difícil, quantidade de anticoagulante inadequada, processos infecciosos, indução pelo EDTA, satelitismo plaquetário, aglutininas plaquetárias frias e plaquetas gigantes. 4,[14][15][16][17][18][19] A detecção de contagens de plaquetas falsamente diminuídas através da avaliação plaquetária em lâmina é muito importante, sobretudo para evitar a investigação e o tratamento desnecessários do paciente. Há exemplos em que a pseudotrombocitopenia conduziu a um diagnóstico equivocado de púrpura trombocitopênica idiopática e consequente tratamento com corticosteroides, transfusão de concentrados de plaquetas desnecessária e até mesmo esplenectomia.…”
