The TEG® analyzer provides a reduced-risk, low-cost, rapid way to determine differential diagnosis and treatment in various hemostatic conditions. The TEG® analyzer reduces overall cost of patient care by reducing costs associated with coagulation monitoring. By reducing the frequency and volume of transfusions, reducing the rate of re-exploratory surgery, reducing risk of exposure to multiple donors, and reducing the number of commonly-used coagulation tests, significant cost savings accrue, and better patient care is achieved.
