Study Notes
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.
