Coagulation Section

• Activated partial thromboplastin ( APPT PTT ) - Evaluates the intrinsic system of the coagulation cascade and monitors time heparin therapy
• Antithrombin llI Screening test for increased clotting tendencies
• Anti-Xa heparin assay - Monitors unfractionated heparin therapy
• Proteins C and S - Evaluate venous thrombosis
• Bleeding time ( BT ) or Platelet Aggregation - Evaluates the function of platelets
• D-dimer - Measures abnormal blood clotting and fibrinolysis
• Factor assays - Detect factor deficiencies that prolong coagulation
• Fibrin degradation products (FDP) Test for increased fibrinolysis (usually a STAT test drawn in a special tube)
• Fibrinogen - Determines the amount of fibrinogen in plasma
• Prothrombin time (PT) and international normalized ratio ( INR ) - Evaluates the extrinsic system of the coagulation cascade and monitors Coumadin Therapy
• Thrombin time (TT) - Determines if adequate fibrinogen is present for normal coagulation
