Although the modern haematology analyzers provide reliable full blood counts, there are interferences on the measurement of platelet counts, especially in patients which have a wide variety of abnormal erythrocytes. We report a patient with heterozygous beta- thalassaemia and pseudothrombocytosis (spurious elevation of platelet count). The case emphasizes, that impedance method is associated with spuriously high platelet counts in thalassemia patients. Optical platelet counts and blood smear review are recommended alternative platelet counting methods in patients with abnormal red blood cells.

Key words: pseudothrombocytosis, spurious platelet count, thalasseamia
