TEG
Viscoelastic
This testing is intended to be used to provide a rapid qualitative and quantitative indication of the coagulation state of a cardiovascular surgery or actively bleeding patient. The clot firmness changes in a sample of citrated whole blood as the sample clots, retracts and lyses in real time. The analyzer output consists of a qualitative graphical representation (mirrored coagulation curve – clot firmness over time) and several defined numeric parameters describing the curve quantitatively.
Note: For total artificial heart indications (ANW only), a separate sendout protocol must be arranged with the laboratory. Refer to TEG with heparinase, TEG with platelet inhibition/mapping, or TEG without heparinase).
For inpatients ONLY at Allina Health ANW, Mercy or United Hospitals
- All Coagulation tubes must be filled to the frosted indicator line or minimum fill line
- Tubes for ROTEM testing and Routine coagulation cannot be interchanged
- Immediatley following collection, mix sample thoroughly by gentle inverting 8 - 10 times, to prevent clotting
