Clinical Significance
The TEG instrument with cartridge utilizes a whole blood sample to analyze the process of clot formation and lysis. The results are displayed in a table and on a graphical tracing that reflects the hemostasis profile of clot formation and fibrinolysis on the sample submitted for testing.
