Each objective below describes a competency you will apply at the immunohematology bench, practical laboratory reasoning first, memorization second.

  • Describe IgG monomer structure and its ability to cross the placenta
  • Explain why IgG antibodies typically require 37°C incubation and the antihuman globulin (AHG) phase for laboratory detection
  • Explain why most clinically significant unexpected red-cell antibodies are IgG
