A Useful Method for the Detection of Ethylenediaminetetraacetic Acid- and Cold Agglutinin-Dependent Pseudothrombocytopenia

In clinical laboratories, a significant portion of the cases with low PLT counts was attributable to EDTA-PTCP and, therefore, did not require treatment. Even if these cases can be detected by bringing the blood samples containing EDTA to 37°C or by adding KN to blood samples containing EDTA, the use of blood samples containing citrate taken for erythrocyte sedimentation rate analysis is a more practical priority method.
