Platelets prepared by apheresis should contain at least:

Platelets prepared by apheresis are required to contain a minimum of 3 x 10 to the 11th platelets, which is reflected in the correct choice. This quantity ensures that the apheresis platelet unit is adequate for therapeutic transfusions, providing sufficient platelet count to effectively manage conditions such as thrombocytopenia or to support patients undergoing chemotherapy, surgery, or those with clotting disorders.

The specified minimum is designed to enhance patient outcomes, as a lower platelet count in transfusion products might not adequately support hemostasis in patients with low platelet levels. This standard is established by regulatory guidelines and best practices to optimize the efficacy and safety of platelet transfusions.
