ROTEM® Analysis: Thromboelastometry
While standard clotting assays just detect the starting time of clotting, thromboelastometry (TEM®) provides information on the whole kinetics of haemostasis: clotting time, clot formation, clot stability and lysis.
The different parameters in thromboelastometry (TEM®) are dependent on:
- the activity of the plasmatic coagulation system
- platelet function
- many factors which influence these interactions, including several drugs
This gives a complete view of the secondary haemostasis.
ROTEM® Analysis: Impedance Aggregometry
The measurement result is shown on three different Parameters: A6 (amplitude after 6 min), AUC (area under the curve) and MS (maximum slope).
A6 (Ohm): A6 shows the measured impedance at the measurement time of 6 minutes as amount of platelet aggregation.
Maximum Slope (Ohm/min): MS is the maximum slope of the aggregation graph and a measurement rate of aggregation.
Area under the curve (Ohm*min): AUC contains the area under the aggregation curve from the start of measurement to 6 minutes, and provides information on the overall platelet aggregation.
