26164 TEG Citrated Kaolin on 5000

​TEG, Thromboelastography

​Kaolin TEG (R, K, angel, MA, LY30)

​Note: Test is only orderable at MMC – Marshfield
Do not use a needle smaller than a 21 gauge for collection.  Obtain appropriate volume of blood in first tube labeled DISCARD.  Obtain full tubes for sample specimens.  It is best to store tubes by laying them on their side, instead of standing them in a rack.  Deliver to lab immediately. Sample must arrive in lab within 15 minutes of collection. Cannot be shared with other coagulation tests.

Do not centrifuge sample. Keep sample at room temperature. Send tubes ASAP in 4" or 6" tube system.  If using 6", use foam inserts in carrier.  Call 1-6363 to notify.

​Heparin

​Assessing hypo- and hypercoagulable states in patients in ICU; aid in the rapid assessment of hemostatic imbalance and guide appropriate blood component therapy when managing perioperative bleeding in postsurgical patients; and monitoring hemostasis in patients with end-stage liver disease who need interventional procedure and/or management of major bleeding.

Thromboelastograph (TEG) is a global assessment of hemostasis and measures the ability of a whole blood sample to form a clot.  The TEG assay measures the viscoelastic changes induced by clot formation and evaluates adequacy of coagulation factors and platelet function as well as the rate of formation of a clot, its strength, stability, retraction and lysis.  The four key parameters of the TEG tracing are: (1) R or reaction time to initial clot formation; (2) Angle or rate of clot formation, (3) MA (maximum amplitude) or maximum strength of clot, and (4) LY30 or percent clot lysis 30 minutes after the MA.

Note: If patient is on heparin, order TEGHEP along with TEG.
