Each objective below describes a competency you will apply at the chemistry bench, not rote definitions in isolation.

  • Place CA 19-9 in pancreaticobiliary monitoring contexts
  • Recognize cholestasis and benign biliary disease as non-malignant elevations
  • Apply Lewis antigen awareness . Lewis-negative patients may not produce CA 19-9
