• Thromboelastometry
    • Assesses interaction between fibrinogen, platelets and clotting factors. It's magnitude of output is related to the fibrin-platelet bond
    • TEG measurement
      • Clotting time (R)
        • From start of curve to 1mm wide. Coagulation factor activation.
      • Clot formation time (K)
        • Time taken for graph to widen from 1mm to 20 mm. Coagulation factor amplification. Reference for clot firmness
      • Alpha angle (α)
        • From midline to 1mm point tangental to the curve. Indicates speed of clot formation
      • Clot firmness (MA)
        • Curve at it's widest point and represents clot strength
      • Lysis time
        • Decrease time from MA - decrease of > 15% indicates fibrinolysis. Measured at 30 mins and 60 mins after MA recorded.
      • Lambda angle
        • Angle showing lysis rate
    • CEACCP
