Viscoelastic testing (VET) has advanced for assessing blood clot dynamics, offering rapid point-of-care analysis. Despite limitations, VET is expanding for managing coagulopathy in diverse patient groups.

Area of Science:

  • Hemostasis and Thrombosis Research
  • Point-of-Care Diagnostics
  • Clinical Coagulation Analysis

Background:

  • Viscoelastic testing (VET) originated for guiding transfusions in trauma and surgery.
  • Early VET methods (TEG, ROTEM) measured mechanical clot resistance.
  • Recent innovations include automated systems and novel detection methods like sonorheometry.

Purpose of the Study:

  • To review the evolution and current applications of viscoelastic testing (VET).
  • To highlight advancements in VET technology and its expanding clinical utility.
  • To discuss limitations and future directions for VET in managing coagulopathy.

Main Methods:

  • Review of viscoelastic testing technologies and their historical development.
  • Analysis of current clinical indications and expanding patient populations for VET.

  • Discussion of technical limitations and future innovations in VET.

    • Main Results:

    • VET systems have become more precise, rapid, and user-friendly.
    • VET is increasingly used in trauma, surgery, liver transplantation, obstetric hemorrhage, DIC, and emerging populations.
    • Limitations persist in detecting anticoagulants and certain bleeding disorders; pediatric use faces barriers.

    Conclusions:

    • VET is evolving into a crucial tool for real-time, individualized coagulopathy management.
    • Integration with EMRs, AI, and improved platelet function assays will enhance VET's clinical utility.
    • Continued guideline development and evidence generation will support VET's expanding role.
