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

  • Interpret hypo- and hyperkalemia with critical-value awareness
  • Recognize pseudohyperkalemia from hemolysis, delayed separation, and fist-clenching/tourniquet effects
  • Apply specimen validity checks before releasing potassium results
