Clinical Information

The Global Hemostasis with Lysis Assay is used to assess clinical conditions in a trauma setting to assess hemorrhage or thrombosis conditions. The TEG 6S system is intended for in vitro diagnostic use to provide qualitative function and semi-quantitative indications of the hemostasis state of a whole blood sample.

CK = Citrated Kaolin
R: Reaction time. The amount of time between the start of the test and the beginning of coagulation.
LY30: Fibrinolysis after 30 minutes of reaching maximum clot strength.
CRT = Citrated Rapid TEG
CFF = Citrated Functional Fibrinogen MA

Ordering Instructions

For TEG Manager Access: Place a ServiceNow request and request "TEG Viewer"

Collection Instructions:

Global Hemostasis Assay:

  • Provides a complete picture of a patient’s hemostasis status with a functional measurement of clotting factors, platelets, fibrinogen.

Venipuncture:

  • Use a 21-gauge needle or larger - a 21-gauge butterfly with tubing is OK.  Never use a smaller gauge needle.
  • Draw a discard tube (no additive or light-blue top marked “discard”) or discard syringe of 3-5 ml prior to collecting blood for TEG® analysis - required.
  • Completely fill a 3.2% Sodium Citrate Light Blue Top BD tube. 
  • Immediately gently invert the tube 5 times.

Arterial Line or Central Line:

  • Draw per the population appropriate Central Venous Catheter (CVC): Insertion, Maintenance, Utilization and Removal policy or Arterial Line: Insertion, Maintenance, Obtaining Samples, and Removal Policies.

Key Points:

  • Do not use heparinized syringes.
  • If closed blood sampling system is not in use, draw a discard tube (no additive or light-blue top marked “discard”) or discard syringe of 3-5 ml prior to collecting blood for TEG® analysis - required.
  • The amount of waste required is:
    • Adult- 5ml
    • Pediatric- 4ml
    • Neonatal- 2ml
  • Completely fill a 3.2% Sodium Citrate Light Blue Top tube (2.7 ml or 1.8 mL)
  • Immediately gently invert the tube 5 times.

Specimen Transport:

  • Walk all TEG specimens to the Blood Bank and clarify to the recipient that the item is a TEG
  • Do not use the pneumatic tube system.

When Collecting for Both Assays (Global Hemostasis with Lysis & Platelet Mapping) draw order:

  • 3.2% Sodium Citrate light-blue top tube marked discard (if from arterial line or central line closed blood sampling system is in use-skip this step).
  • 3.2% Sodium Citrate light-blue top tube.
  • Lithium Heparin Non-Gel Green top tube.

If there are questions regarding ordering and/or collection, please contact the Lab Call Center. If there are questions regarding interpretation please contact Dr. Peter Millward, Medical Director of Point of Care or the Clinical Pathologist on call.
