Thromboelastometry (TEM), previously named rotational thromboelastography (ROTEG) or rotational thromboelastometry (ROTEM), is an established viscoelastic method for hemostasis testing in whole blood. [1] It is a modification of traditional thromboelastography (TEG).
Thromboelastometry (TEM), previously named rotational thromboelastography (ROTEG) or rotational thromboelastometry (ROTEM), is another version of TEG in which it is the sensor shaft, rather than the cup, that rotates.
Articles relating to blood tests, laboratory analysis performed on a blood sample that is usually extracted from a vein in the arm using a hypodermic needle, or via fingerprick.
Cytochalasin has found practical application in thromboelastometry (TEM) whole blood assays for the assessment of fibrinogen and fibrin polymerization disorders in the FIBTEM assay on ROTEM. This test is based on the principle that cytochalasin D very effectively inhibits platelet function by inhibition of the contractile elements. [ 8 ]
Alternatively, a more rapid detection of fibrinolytic activity, especially hyperfibrinolysis, is possible with thromboelastometry (TEM) in whole blood, even in patients on heparin. In this assay, increased fibrinolysis is assessed by comparing the TEM profile in the absence or presence of the fibrinolysis inhibitor aprotinin. Clinically, the ...
Thrombosis (from Ancient Greek θρόμβωσις (thrómbōsis) 'clotting') is the formation of a blood clot inside a blood vessel, obstructing the flow of blood through the circulatory system.
Fibrinogen analysis can also be tested on whole-blood samples by thromboelastometry. This analysis investigates the interaction of coagulation factors, their inhibitors, anticoagulant drugs, and blood cells (specifically, platelets), during clotting and subsequent fibrinolysis as it occurs in whole blood.
The diagnosis of hyperfibrinolysis is made indirectly with immunochemical methods which detect the elevation of biomarkers such as D-Dimer (cross-linked fibrin degradation products), fibrinogen split products (FSP), complexes of plasmin and alpha-2-antiplasmin (PAP).
