Useful For
Restricted and only available for ordering at the Weston campus.
Patients undergoing cardiovascular surgery for evaluating patient's baseline hemostasis and ability for clot formation; monitoring any residual heparin post protamine; and/or guiding goal-directed transfusion therapy when there is intraoperative or postoperative bleeding.
Note: LY30 not reported since it is not FDA cleared on this test cartridge. For patients fully heparinized on bypass, only the R-H parameter of the TEG6S is reported. Display of the other TEG6s parameters for patients on heparin is dependent on the dose and effect of heparin on the patient's hemostasis.
