Comments:
This test needs a separate tube! It CANNOT be performed with any other coagulation tests except the TEG.
Methodology:
A stationary pin attached to a torsion wire is immersed into whole blood. When the first fibrin forms, it begins to bind the cup and pin, causing the pin to oscillate in phase with the clot. A mechanical- electrical transducer converts the rotation movement of the pin to an electrical signal which is monitored by a computer.
