Program Description
This program will describe the structure, distribution, and clinical significance of the Duffy Blood Group System. Antibodies to Duffy antigens are usually clinically significant and have been reported to cause hemolytic disease of the fetus and newborn. The FY glycoprotein, atypical chemokine receptor 1 ACKR1 will be explored and altered expressions of the alleles will be defined. Case studies will demonstrate how antibodies in this blood group may be detected in the blood bank.

Learning Objectives
After participating in this educational activity, participants should be able to:

• Describe the clinical significance of antibody formation to the Duffy antigens in clinical practice.
• Explain the significance of the GATA promoter region mutation as it relates to individuals who appear Fy(a-b-).
• Highlight the role of the Duffy glycoprotein in malarial infections.
• Explore the functional aspects of the FY Glycoprotein, ACKR1.
• Apply the known serologic characteristics of the antibodies in the Duffy system to resolve complex serologic case studies.

How to Claim Continuing Education Credit

• Single Viewers: if you registered as a single viewer, complete the evaluation found on the "CE Information" tab after watching the video. By submitting the evaluation, you are attesting to watching the presentation in its entirety.
  
• Group Viewers: This is applicable for groups/facilities that purchased Group Viewing access for this program (registration will be verified prior to processing a group viewing attendance log). Group Viewing Coordinators should submit the attendance log to eLearning@aabb.org within 72 hours of the completion/viewing date. Once AABB receives an attendance log, each participant on the attendance log will be granted access as a single viewer to this program and will be required to complete the evaluation in order to claim continuing education credit.
