Platelet aggregation is important in hemostasis. A clump of platelets surrounds an area of acute blood vessel endothelial injury. Normal platelets adhere to this area of injury, and through a series of chemical reactions, they attract other platelets to the area.

Platelet aggregation may be defined as the interaction of activated platelets with one another and occurs after adhesion of platelets to the wall of the injured blood vessel. A series of factors are capable of inducing platelet aggregation and may be classified as primary and secondary platelet .

The principles behind the platelet aggregation assay are very straightforward. By gently centrifuging a blood sample, we generate plasma that is cloudy with suspended platelets (platelet rich plasma, PRP). If activated, the platelets in PRP will start to stick together, forming aggregates.

On contact with collagen, platelets become activated, with platelet adhesion, secretion of platelet contents, and platelet aggregation at the site of injury. The activated platelet surface is an essential catalytic surface for several coagulation reactions that generate thrombin, a key factor in the coagulation sequence [D'Souza D, et al ...

Platelets play a major role in secondary hemostasis as well. For example, platelets provide a surface for the assembly of several enzyme complexes that form during the process of coagulation, provide coagulation factor V, and participate in the activation of factor X. Collagen stimulates platelet aggregation and platelet adhesion.

Platelets adhere to one another and to collagen under the endothelium, forming a platelet plug. On the surface of the activated platelet are glycoprotein IIb/IIIa and VWF receptors . The former is a receptor which binds fibrinogen .
