Description Module

Brief Summary

The purpose of this study is to see if there is a racial and/or gender difference in platelet aggregation.

Detailed Description

Genetic variability of various components of the coagulation system has been reported. Data on racial and gender differences in platelet aggregation are lacking.

We hypothesize that there are significant racial and gender differences on aggregatory response of platelets to commonly used agonists to evaluate platelet function such as adenosine diphosphate (ADP), epinephrine, collagen and arachidonic acid.
