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

  • Map Fya and Fyb antigens to common Duffy phenotypes and explain why anti-Fya/anti-Fyb are generally clinically significant
  • Predict how proteolytic enzyme treatment of panel cells typically affects Duffy antibody reactivity and use that clue in identification logic
  • Describe Fy(a−b−) phenotype context (including malaria-resistance educational framing) without overgeneralizing population genetics as clinical dogma
