Multicomponent donor apheresis in the Americas.

Area of Science:

• Blood Transfusion Medicine
• Apheresis Technology

Background:

• Multicomponent donor apheresis collects red blood cells, platelets, and plasma simultaneously.
• The United States leads in adopting apheresis technology in the Americas.
• Increased apheresis collections correlate with higher infectious agent deferrals.

Purpose of the Study:

• To analyze the impact of multicomponent donor apheresis on blood collection practices.
• To identify key challenges and future trends in apheresis donation.

Main Methods:

• Review of apheresis collection data and donor deferral reasons.
• Analysis of trends in whole blood and apheresis donations.
• Examination of deferral categories, focusing on hemoglobin/hematocrit levels.

Main Results:

• Hemoglobin/hematocrit deferrals represent the most significant upfront barrier for volunteer donors.
• While infectious agent deferrals have increased with apheresis, hemoglobin/hematocrit remains the primary issue.
• Apheresis technology is becoming more refined and widely adopted.

Conclusions:

• Multicomponent donor apheresis is a growing method for blood product collection.
• Addressing hemoglobin/hematocrit deferrals is crucial for increasing donor participation.
• Apheresis may become the dominant blood collection method in the future.
