WebCauses of platelet clumping include platelet activation (due to traumatic venipuncture) and EDTA-dependent antibodies that react with platelet glycoprotein IIb/IIIa. In the latter case, the clumping can be corrected by using blood collection tubes containing an alternative anticoagulant, such as sodium citrate. WebPseudothrombocytopenia (PTCP) or spurious thrombocytopenia is an in-vitro sampling problem which may mislead the diagnosis towards the more critical condition of …

WebFalse decreases in platelet counts result from both platelet clumping, often the result of insufficient anticoagulation in a collection tube, or so-called “giant platelets.” These larger than average platelets, shown circled in the picture on the right, can approximate the size of RBCs and thus, are counted in the RBC count.
