Donated blood is not transfused as ‘whole blood’, but is separated into separate products, most commonly red blood cells, platelets, and plasma. Plasma separated from whole blood and frozen within 18 hours of collection is known as fresh frozen plasma (FFP).

Fresh frozen plasma can be given in clinical situations where there is active bleeding and abnormal clotting.  FFP from which of the following donors would be suitable for an individual with B+ blood? (Choose all that apply).

(Hint: what immune component is in plasma?)
