Platelet Aggregation
Aggregation involves platelet-to-platelet adhesion, and is necessary for effective hemostasis following the initial adhesion of platelets to the site of injury, described above in Chapter 3. Following adhesion, platelets are activated by a number of agonists such as adenosine diphosphate (ADP) and collagen present at the sites of vascular injury. These …

Performance and usefulness of platelet aggregation testing
The review by Frelinger is devoted to the performance and utility of methods assessing such αIIbβ3 activation, mainly measurement of PAC1 binding to platelets by flow cytometry. Finally, platelet activation also promotes interaction with other blood cells such as leukocytes, and these platelet-leukocytes have implications in human health.
