Part II: white blood Obtaining accurate platelet counts in patients with thrombocytopenia using automated hematology analyzers is still challenging even when the most expensive and precise analyzers are used. Our results showed that the impedance method overestimated the platelet counts and also failed to provide any result in 15% of samples.

Such results can result in inappropriate investigations or treatment decisions in patients. Spuriously normal or high platelet counts carry the risk of under diagnosis of the true thrombocytopenia with adverse clinical implications. We present a patient with smoldering myeloma with spurious platelet count due to cryoglobulins. The three other conditions would instead lead to suppression of all test results and blinding of these to the clinicians since (i) one corrective formula would not be adequate for all cases in the presence of a high degree of interindividual variation of results, or (ii) the correction of results by any corrective equation would hypothetically

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).
