Objectives

  • Outline the background and development of the ABO system.
  • List antigens and antibodies of the system, including A subgroups.
  • Discuss the inheritance of the ABO antigens, including explanations of genotypes and phenotypes.
  • Discuss development of serum antibodies with respect to "naturally" occurring antibodies and immune antibodies.
  • Explain the procedure for routine ABO slide and tube typing and interpretation of results.
  • Determine the ABO blood group, given the forward and reverse typing results.

Additional Information

Level of Instruction: Intermediate
 
Intended Audience: Medical Laboratory Scientists (MLS), Medical Laboratory Technicians (MLT) and Medical Laboratory Science students who wish to review basic principles of the ABO blood group system.
 
Course Description: This course explains the basic genetics and principles of the ABO blood group system, as well as the tube methods for forward and reverse ABO grouping. Learners will benefit most from this course if they already possess a basic understanding of genetic principles, immune response, the production and structure of antibodies, and antigen-antibody reactions.
