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.
Platelet transfusions came into medical use in the 1950s and 1960s. [1] [5] It is on the World Health Organization's List of Essential Medicines.
