Abstract

Ethylenediaminetetraacetic acid (EDTA)-dependent pseudothrombocytopenia (PTCP) is the phenomenon of a false low platelet count reported by an automated haematology analyzer due to in vitro aggregation of platelets. This aggregation is due to the interaction between antibodies and EDTA-dependent crypt antigens on platelets. We observed a new born child whose mother was diagnosed with transient PTCP due to transplacental transmission of maternal immunoglobulin G antibodies during pregnancy. Conclusion: Although maternal–neonatal PTCP is rare, it is important to consider this phenomenon as a cause of trombocytopenia, as it can result in unnecessary diagnostic workup and treatment.
