Program Description
Viscoelastic assays – Thromboelastometry (ROTEM) or Thromboelastography (TEG) – continue to be valuable for the assessment and management of major bleeding in trauma, cardiovascular surgery, post-partum hemorrhage and liver transplant. Heightened attention was brought to these tests when the FDA recently expanded their indications for use to include hospitalized patients suspected of a COVID-19 associated coagulopathy. Experts will first describe these assays, review the advantages and disadvantages compared to conventional coagulation tests, and explain how parameters can rapidly identify underlying coagulopathies and guide goal-directed blood component therapy. Next, the discussion will shift to the FDA guidance and the value of this technology in the assessment and management of hypercoagulability in COVID-19 patients. An extended Q&A period will follow presentations to give the audience an opportunity to join the discussion.

Learning Objectives
After participating in this educational activity, participants should be able to:

  • Describe the basic principles and clinical utilization of viscoelastic testing in bleeding and thrombosis, including in the hypercoagulability in COVID-19 patients.
  • Explain the key parameters for both assays and how these parameters reflect the various aspects of clot formation.
  • Discuss potential institutional hurdles to the adoption of viscoelastic testing.
  • Interpret the recently issued FDA guidance that provides for the modified use of these devices to facilitate patient management during the COVID-19 public health emergency.

Program Sponsors
This program is complimentary to AABB members through the generous support of Haemonetics and Instrumentation Laboratory.
