Thromboelastograph, non-cardiac-8962
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
- Do not over or under fill tube as the ratio of anticoagulant to whole blood is critical
- Tubes for ROTEM testing and routine coagulation cannot be interchanged
- Immediately following collection, mix by inverting 8 - 10 times to prevent clotting
Lt blue Sodium citrate (NaCit) - 2.7mL
Ambient - 4 hours (2 hours if patient is on Heparin)
Specimen MUST be walked down to the laboratory
- Incorrect volume
- Exceed standard testing time, delay in transport
- Incorrectly labeled or mislabeled
- Clotted
Available at the Central Laboratory and Mercy and United hospitals.
