DIC Laboratory Testing Quiz

DIC Lab Testing

• Laboratory testing in DIC is characterized by consumption of clotting factors and platelets.
• A normal laboratory finding in DIC is increased erythrocyte sedimentation rate (ESR).
• Decreased platelet count in DIC indicates severe clotting problems and bleeding risk.
• DIC results in the paradoxical occurrence of excessive clotting and bleeding.
• Decreased platelet counts in DIC can signify thrombocytopenia, indicating impaired platelet function.
• Decreased fibrinogen levels are least expected in DIC.
• A decreased platelet count in DIC implies impaired hemostatic function, leading to increased bleeding.
• The primary culprit for DIC's lab abnormalities is activation of the coagulation cascade.
• Decreased platelet counts in DIC often manifest clinically as bleeding, particularly mucosal bleeding.
• Platelet aggregation studies directly evaluate platelet function changes in DIC.

Laboratory Testing in DIC

• A key characteristic of laboratory testing in DIC is consumption of clotting factors.
• Elevated D-dimer is a laboratory finding associated with DIC
• Elevated prothrombin time (PT) is a laboratory finding associated with DIC
• Elevated partial thromboplastin time (PTT) is a laboratory finding associated with DIC
• Decreased fibrinogen levels is a laboratory finding associated with DIC
• Increased fibrin degradation products (FDPs) is a laboratory finding associated with DIC
• A decreased platelet count is a laboratory finding associated with DIC
• Elevated levels of antithrombin III is NOT a laboratory finding associated with DIC
• Decreased fibrinogen levels may indicate widespread clotting and consumption of clotting factors.
• Decreased platelet count suggests impaired hemostatic function due to consumption or impaired production.
• Decreased platelet count in DIC may indicate an inability to form new blood clots.
• Decreased platelet count in DIC may result in bleeding.
• Consumption of clotting factors is primarily responsible for the observed laboratory abnormalities in DIC.
• Platelet count would most directly indicate a significant change in platelet function.
