Despite the many components entering into hemostasis, these facts override all others: 
 

• The end result of the hemostasis process is a single product — the clot.
• The clot is a mechanical device.
• The clot is a damage-control device, a temporary stopper, that gradually dissolves during vascular recovery.

• The TEG® analyzer measures the mechanical properties of the developing clot and its ability to perform useful mechanical work (the work of hemostasis) throughout its structural development.
