Thrombocytopenia, EDTAAbstract
Ethylenediaminetetraacetic acid is an anticoagulant widely used in health sciences in the processing of medical samples. Given that, in the presence of certain immune conditions, this agent can induce a false low platelet count (pseudothrombocytopenia), it must be considered as part of the differential diagnosis for thrombocytopenia. The case presented is about a 68 year old patient with severe thrombocytopenia with no clinical evidence of bleeding, which was later demonstrated as pseudothrombocytopenia induced by EDTA. The presence of a false thrombocytopenia was demonstrated adding amikacin to the blood sample.
