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.

Types of platelet function disorders | Hemophilia

Three platelet function disorders involve platelet secretion. 1) In Alpha Granule Deficiency, called Gray Platelet Syndrome, there is a lack of important proteins within the alpha granule inside the platelet. This problem slows down normal platelet adhesion, aggregation and repair of the blood vessel.

Thrombocyte Aggregation - an overview | ScienceDirect Topics

Platelet Aggregation Testing with Lipemic, Hemolyzed, or Thrombocytopenic Samples. Platelet aggregation measures the ability of platelets to adhere to one another and form the hemostatic plug, which is the key component of primary hemostasis [30]. It can be performed using either platelet-rich plasma or whole blood.

They contain many important components for these functions, of which surface glycoproteins are critical for two processes, adhesion and aggregation. In platelets, adhesion refers to the attachment of platelets to subendothelium or to other cells, while platelet-platelet “adhesion” is called aggregation to

Platelet Function Testing: Light Transmission Aggregometry

Platelet aggregation testing measures the ability of various agonists to platelets to induce in vitro activation and platelet-to-platelet activation. Classically Born aggregometry uses platelet rich plasma [PRP] but whole blood aggregometry can be also used. In the Born aggregometer, PRP is stirred in a cuvette at 37°C and the cuvette sits ...
