Pseudothrombopénie non EDTA-dépendante: à propos d’un cas

Pseudothrombocytopenia is a rare phenomenon in laboratory explained by in vitro agglutination of platelets. Microscopic examination of the peripheral blood smear is of key importance to confirm the diagnosis and to avoid any inappropriate or dangerous clinical and therapeutic decision. Its occurrence in a patient, under treatment with heparin, raises the problem of differential diagnosis of heparin-induced thrombocytopenia. The aim of this study was to eliminate any confusion between this purely artefactual phenomenon and heparin-induced thrombocytopenia.
