The ex-tem^® assay is a semi-quantitative in vitro diagnsotic assay used to monitor the coagulation process via the extrinsic pathway in citrated whole blood specimens on the ROTEM^®delta.  Clotting characteristics are descrived by the functional parameters Clotting Time (CT), Speed of CLot Formation (CFT and alpha angle), Clot Firmness (A20/MCF) and Clot Lysis (LOT,ML, LI(x)).
The indication for ROTEM^®delta use is with adult patients where an evaluation of their blood coagulation properties is desired. Coagulation evaluations with ROTEM^®delta are commonly used to access clinical conditions in organ transplantation, cardiovascular surgery, cardiology procedures, and trauma to assess post-operative hemorrhage and/or thrombosis.
The ex-tem^® reagent is always used in combination with star-tem^® for sample recalcification.
