Interpretive

Use:

Assess platelet function in patients who have received platelet inhibiting drugs such as aspirin, clopidogrel, abcixmab, tirofiban or epitifbatide.



TEG Thromboelastograph Coagulation Analyzer TEG 5000 Series testing is indicated for use with adult patients where an evaluation of their blood coagulation properties is desired. Coagulation evaluations are commonly used to assess clinical conditions such as post-operative hemorrhage and/or thrombosis during and following cardiovascular surgery, organ transplantation, trauma and cardiology procedures.



Assesses hemorrhagic or thrombotic risk by measuring rate of clot formation, strength and stability of clot; the effect of platelets, coagulation factors and cellular interactions; maximum platelet function.
