Will I need a platelet transfusion?

Platelets for transfusion are either collected from a single donor or produced by combining platelets taken from four separate blood donations. Platelets from a single donor are collected using a special machine which separates platelets from blood. To make sure the platelets can work effectively, they must be stored at between 20 and 24°C on an

Platelet transfusion should be given only after the risks associated with transfusion have been considered and only when the benefits outweigh the risks.
