Platelet donation by a single line automatic separation and leukocyte reduction apheresis machine at an Australian donation centre in 2020 Platelet donation by a double catheter at a US donation center in 2022. Blood is drawn from the right arm, platelets are extracted using the machine, and the remaining blood components are returned through ...
Platelets for transfusion can also be prepared from a unit of whole blood. 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 enough for an adult therapeutic dose. [20]
The yield is normally the equivalent of between six and ten random platelet concentrates. Quality control demands the platelets from apheresis be equal to or greater than 3.0 × 10 11 in number and have a pH of equal to or greater than 6.2 in 90% of the products tested and must be used within five days. Leukapheresis – leukocytes (white blood ...
Blood compatibility testing is routinely performed before a blood transfusion.The full compatibility testing process involves ABO and RhD (Rh factor) typing; screening for antibodies against other blood group systems; and crossmatching, which involves testing the recipient's blood plasma against the donor's red blood cells as a final check for incompatibility.
During a platelet donation, the blood is drawn from the patient and the platelets are separated from the other blood components. The remainder of the blood, red blood cells, plasma, and white blood cells are returned to the patient. This process is completed several times for a period of up to two hours to collect a single donation. [78]
Blood bank in France. A blood bank is a center where blood gathered as a result of blood donation is stored and preserved for later use in blood transfusion.The term "blood bank" typically refers to a department of a hospital usually within a clinical pathology laboratory where the storage of blood product occurs and where pre-transfusion and blood compatibility testing is performed.

Platelets are either isolated from collected units of whole blood and pooled to make a therapeutic dose, or collected by platelet apheresis: blood is taken from the donor, passed through a device which removes the platelets, and the remainder is returned to the donor in a closed loop. The industry standard is for platelets to be tested for ...
