Protocolo diagnóstico de la trombocitosis

Thrombocytosis is defined as a peripheral blood platelet count above the reference value (more than 450000/μl). Thrombocytosis can be of primary etiology (such as a clonal disorder of the bone marrow, either acquired or congenital), but the most frequent cause is thrombocytosis reactive to other diseases. There is also pseudothrombocytosis due to «errors» in automatic analyzers, in which various blood elements can be misinterpreted as platelets. It is important to make a good differential diagnosis because of the prognostic and therapeutic implications of thrombocytosis.
