Edta induced pseudothrombocytopenia
Web1 INTRODUCTION. Pseudothrombocytopenia (PTCP) is an in vitro reaction in which a spuriously low platelet count results from blood anticoagulation due to in vitro platelet agglutination, mainly following the use of ethylenediaminetetraacetic acid (EDTA), which chelates divalent cations such as calcium to prevent coagulation. WebJan 13, 2024 · Data showed that anticoagulants such as citrate and/or heparin-dependent PTCP (16.0%) became increasingly common, whereas ethylenediaminetetraacetic acid (EDTA)–induced PTCP (49.1%) remained the most frequent. We note that that nearly half of the patients with PTCP had veritable decreased PLT counts, even after PLT levels …
