Platelet Aggregation Systems (Aggregometer)


Platelets are small cell fragments most commonly known for playing a role in wound repair and blood clotting via a clumping process known as platelet aggregation. Platelet aggregation systems (also referred to as an aggregometer) can be used to determine how well platelets stick together.

Platelets secrete thromboxane A2, which acts on the platelet's own thromboxane receptors on the platelet surface (hence the so-called "out-in" mechanism), and those of other platelets. These receptors trigger intraplatelet signaling, which converts GPIIb/IIIa receptors to their active form to initiate aggregation. Granule secretion
