Pseudothrombocytopenia: a report of a new method to count platelets in a patient with EDTA- and temperature-independent antibodies of the IgM type
Eur J Haematol 2002: 69: 243–247. © Blackwell Munksgaard 2002. Abstract:
Pseudothrombocytopenia is usually associated with blood specimens anticoagulated with ethylenediamine tetraacetic acid (EDTA) or other anticoagulants. It may be caused by temperature-independent, EDTA-dependent antibodies of the immunoglobulin-M (IgM) type. Here a patient with EDTA-independent and temperature-independent pseudothrombocytopenia mediated by IgM or IgM-containing immune complex is reported, and a reliable method is described for a proper counting of platelets in such cases.
