Coagulation assays are screening tools, interpret with specimen quality, reagent context, and institutional reference intervals.

  • Describe thrombin time as direct thrombin + fibrinogen clotting assay
  • Recognize prolongation from hypofibrinogenemia, dysfibrinogenemia, heparin, fibrin degradation products
  • Use reptilase time concept to distinguish heparin vs fibrinogen issues
  • Apply institutional reference interval
