Pseudothrombocytopenia masking true thrombocytopenia
American Journal of Hematology
|March 1, 1985
Abstract:
Pseudothrombocytopenia owing to platelet clumping is usually associated with blood specimens anticoagulated with EDTA. It may also be seen if specimens possessing IgM cold agglutinins are processed at room temperature. A patient with a temperature-independent, EDTA-independent agglutinin is reported whose pseudothrombocytopenia was masking true thrombocytopenia. A technique for blood collection when evaluating similar cases is described.
