Summary

Platelets are circulating blood cells. They bind to each other and to the damaged vessel wall to prevent excessive bllod loss. Unlike quantitative platelet defects, there is no automated, simple test to diagnose qualitative platelets defects. However, these defects expose to bleeding in a surgical situation and could explain the transfusion inefficiency of some platelet concentrates. In recent decades, considerable progress has been made in understanding qualitative platelet disorders. In this project, we propose to submit blood donors to a standardized hemorrhagic diathesis questionnaire and to compare the prevalence of platelet function abnormalities in blood donors with and without hemorrhagic diathesis.

Detailed description

Primary objective specify the prevalence of qualitative platelet disorders in blood donors with i) a clinical history of bleeding diathesis collected through a standardized and validated questionnaire ii) and / or a hematoma (more than 4 cm) that occurred during blood donation. Secondary objectives to obtain the prevalence of other defects of hemostasis
