EDTA-induced pseudothrombocytopenia occurs when ethylenediaminetetraacetic acid (EDTA), an anticoagulant commonly used in blood collection tubes, triggers platelet clumping. EDTA binds to calcium ions, disrupting the balance needed to prevent platelet aggregation. As a result, platelets clump together, leading to an erroneously low platelet count in routine blood tests. To address this issue, alternative anticoagulants like citrate or heparin may be used. Additionally, warming the blood sample b

Platelets clumps. EDTA Pseudothrombocytopenia is a laboratory artifact that can occur when EDTA (ethylenediaminetetraacetic acid), a chelating agent commonly used to preserve blood samples and prevent coagulation, is present in the blood sample at the time of platelet counting. EDTA can cause platelets to clump together, leading to an underestimation of the true platelet count. This can have significant clinical implications, as a falsely low platelet count may lead to inappropriate treatment de
