What is a recommended deferral period for individuals who have taken aspirin before donating platelets?

The recommended deferral period for individuals who have taken aspirin before donating platelets is 48 hours. This is based on the understanding that aspirin can affect platelet function, making them less effective for certain procedures and therapies that require healthy platelets. The 48-hour window allows enough time for the effects of aspirin to diminish, ensuring that the platelets collected are functioning optimally and can support patients adequately.

The other options, such as a shorter or longer deferral period, do not align with current guidelines. A 24-hour period may not provide sufficient time for platelet function to return to normal after aspirin ingestion, while a 72-hour or 1-week deferral could unnecessarily delay the donation process for individuals who are eligible to donate sooner, thereby limiting the available platelet supply for patients in need.
