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

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.

Can sex be determined from a blood smear?

Objective: Originally, this blind study was designed to check whether blood smears constitute reliable tools to determine sex. However, when we analyzed our data some interesting findings immerged and in this paper we try to highlight them.

Material And Methods: 74 blood smears (35 women and 39 men) have been performed and then stained.
