Each objective describes a laboratory competency, screening tests support patterns, not definitive diagnosis alone.

  • Define secondary hemostasis as fibrin stabilization of the platelet plug
  • Relate tissue factor pathway and contact activation to PT and aPTT respectively
  • Recognize consumptive vs deficient coagulation patterns on screening panel
  • Avoid exhaustive biochemical memorization, focus on assay mapping
