Common Coagulation Tests
| Question | Answer |
|---|---|
| Activated Partial Thromboplastin Time | Prolonged times may indicate stage one defects; values reflect adequacy of heparin therapy |
| Bleeding Time (BT) | Increased BT indicates hemorrhagic disorders associated with decreased platelet activity and lack of elasticity of capillary walls |
| D Dimer Test | Evaluates thrombin and plasmin activity and is very useful in testing for disseminated intravascular coagulation (DIC) and used in monitoring thrombolytic therapy |
| Fibrin Degradation Products (FDP) | High levels result in FDP fragments that interfere with platelet function and clotting |
| Fibrinogen | Fibrinogen deficiency suggests hemorrhagic disorders and is used most frequently in obstetrics |
| Prothrombin Time (PT) | Prolonged times may indicate stage two and three defects; values used to monitor warfarin therapy |
