HOW IT WORKS ROTEM® Analysis

 

 TEM_Curves_CBR_kl
Parameter Definition Information
Clotting Time CT (sec) Time to reach 2mm amplitude from beginning of test Speed of fibrin formation; influenced by clotting factors, anti-coagulants
Clot Formation Time CFT (sec) Time to reach 20mm amplitude from the time of 2mm amplitude Kinetics of clot formation; influenced by platelet level / function and fibrinogen level / ability to polymerize
Maximum Clot Firmness, MCF Maximum amplitude (in mm) Firmness of clot, i.e., clot quality; influenced by platelets, fibrinogen (concentration and ability to polymerize), Factor XIII, fibrinolysis
Maximum Lysis, ML (% of MCF) Percent of clot firmess lost during measurement Abnormal ML at 30 minutes likely indicates fibrinolysis

 


ROTEM® Analysis



ROTEM® provides the most complete and rapid information on hemostasis.  Unlike other clotting assays, ROTEM® analyzes whole blood and provides infomation about all stages of the coagulation process.  

ROTEM® tests capture specific paramaeters (described more fully at left) that provide information about the elements affecting hemostasis.

The results of the ROTEM® analysis should not be the sole basis for a patient diagnosis, but should be evaluated together with the patient's medical history (anamnesis), the clinical picture and, if necessary, further coagulation tests.
