Learning Objectives

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

  • Describe the biochemistry and molecular basis of the Kell and Kidd Blood Group System antigens.
  • Discuss the inheritance and serological expression of common Kell and Kidd antigens, including altered and null phenotypes.
  • Discuss the clinical significance of common Kell and Kidd antibodies.
  • Identify the special characteristics of Jk (a-b-) red cells.
  • Explain why Kidd antibodies are a challenge to detect in routine pre-transfusion testing.

Program Description

The Kell and Kidd Blood Group Antigens are red blood cell glycoproteins that can produce antibodies that are highly clinically significant as they can lead to hemolytic transfusion reactions and hemolytic disease of the fetus and newborn (HDFN). This program will describe the structure, molecular and biochemical significance of Kell and Kidd Blood Group Antigens, focusing on the inheritance and serological expression including altered and null phenotypes. In addition, the program will discuss why these antibodies are a challenge to detect in routine pre-transfusion testing.


AABB understands the value of learning together as a group but with COVID-19, bringing everyone together to share the experience in person may not be an option for your team. Given this, all participants in a group will be provided the ability to register as a single viewer (AABB will provide a promocode to registered group viewing coordinators to share with their team in advance of the live program). If you are a group interested in participating in this eCast, simply complete the Group Viewing registration form and AABB will provide detailed instructions to share with your team. For single viewers, the process has not changed.
