Platelets collected by using apheresis at an American Red Cross donation center. Not all platelet transfusions use platelets collected by automated apheresis. The platelets can also be separated from donations of whole blood collected in a traditional blood donation, but there are several advantages to separating the platelets at the time of collection.
How often a donor can donate varies from days to months based on what component they donate and the laws of the country where the donation takes place. For example, in the United States, donors must wait 56 days (eight weeks) between whole-blood donations but only seven days between platelet apheresis donations and twice per seven-day period in ...
Understand the different processes before you decide to give.
Platelets are regulators of hemostasis and thrombosis. Platelets become active in the blood following vascular injury. Vascular injury causes platelets to stick to the cellular matrix that is exposed under the endothelium, form a platelet plug, and then form a thrombus. Platelets are essential in the formation of an occlusive thrombus and are ...
Women who have platelet levels lower than 70,000 / μL, during pregnancy, maybe experiencing severe gestational thrombocytopenia or immune thrombocytopenia. [6] In such cases, if the treatment of immune thrombocytopenia therapy (corticosteroids, or intravenous immunoglobulin) [ 2 ] does not improve the platelet count, the patient will be ...

Platelet transfusion is contraindicated in thrombotic thrombocytopenic purpura (TTP), as it fuels the coagulopathy. Platelet transfusion is generally ineffective, and thus contraindicated, for prophylaxis in immune thrombocytopenia (ITP), because the transfused platelets are immediately cleared; however, it is indicated to treat bleeding. [70]
Platelets for transfusion can also be prepared from a unit of whole blood, whereby 4 or 5 buffy coats are pooled to produce a platelet component. Some blood banks have replaced this with platelets collected by plateletpheresis because whole blood platelets, sometimes called "random donor" platelets, must be pooled from multiple donors to get ...
