A new proposition for the screening of platelet function defects using an hematology analyzer

Abstract

In this paper we suggest a new method for the screening of congenital thrombopathies using an hematology analyzer. This method is an improvement of the platelet count ratio principle which uses an impedance counter to search a decrease of the free platelet count after adding platelet agonist to whole blood. We suggest using novel platelet parameters provided by an optical hematology analyzer such as ADVIA 2120i (Siemens Healthcare Diagnostics) to search morphological and structural changes of platelet that are supposed reflecting platelet activation in normal platelets after addition of an agonist.

Keywords: ADVIA 2120i; Platelet defects; Screening method.
