Thrombocytopenia-case report

Thrombocytopenia is defined as a platelet count less than l50x109/L.There are three fundamental mechanisms of thrombocytopenia: decreased platelet production, increased platelet destruction and pooling of a larger than normal fraction of platelets within the spleen. In surveys reported incidence of pseudothrombocytopenia about 0, 09 to 0, 21 percent when low platelet count reported by automated hematology analyzers, but microscopic examination of the peripheral blood smears show many platelets. The most common artifact causing pseudothrombocytopenia is in vitro clumping of platelets in blood collected into EDTA anticoagulant or attaching platelets to leukocytes and monocytes (rosette). Clamping activity increases over time if samples are left unanalyzed or if a samples are cooled less than 37 C...
