Instructions
For samples drawn by venipuncture, use a 21-gauge needle. The first 3 mL of blood should not be used for TEG testing due to the possible contaminants in the sample during normal phlebotomy. Draw a discard tube if the only sample being drawn will be for TEG testing.
For line draws the first 7 mL of blood should be discarded.

Clinical Significance
Provides a rapid functional measurement of clotting factors, platelets, and fibrinogen, providing a global view of clot rate, strength, and stability for patients at risk for coagulopathy. Primarily intended for use in trauma patients but may be considered in other situations requiring rapid assessment of coagulation.
