Which statement about platelet donor deferral is true?

The statement regarding platelet donor deferral that is accurate pertains to individuals who have taken aspirin. It is established that aspirin can impact platelet function for a period of time because it irreversibly inhibits cyclooxygenase, which plays a crucial role in platelet aggregation. As a result, donors who have ingested aspirin should indeed be deferred for at least 48 hours to ensure that the platelets collected are fully functional and can provide the intended benefits to recipients.

This guideline is important to maintain the integrity of the donated platelets and ensure that they can adequately perform their role in hemostasis when administered to patients. Proper donor screening and adherence to deferral guidelines help ensure that blood products are safe and effective for those in need.
