  1. Prothrombin Time
    (Warfarin)
    • 10-13 seconds
    • Measures the time required to form a fibrin clot after activation of the Extrinsic Pathway, Common pathway.
  2. Partial Thromboplastin Time
    (heparin)
    • 20-35 seconds
    • Measures the time required to form a fibrin clot after activation of the Intrinsic Pathway, Common pathway.
  3. Fibrinogen
    • 200-400 mg/dl
    • If low fibrinogen time high. If high fibrinogen, then time low.
    • The time required for the clot to form is inversely proportional to the fibrinogen concentration.
  4. INR
    • 0.8-1.2
    • 2-3 (warfarin)
  5. FDP
    Negative
  6. D-dimer
    • Negative
    • Product of Fibrin Degradation Products
  7. Clot retraction
    45-85% 24 hours
  8. PFA 100
    CEP1:
    CADP:
    • 80-150 seconds
    • 60-100 seconds
    • Time required to stop blood flow is the closure time (reflects qualitative platelet function).
    • If the CEPI is elevated then CADP is performed.
  9. Thrombin
    < 20 seconds
  10. Platelets
    • 150-450 (103/mm3)
    • Quantitative (numerical) platelet count
