Area of Science:

  • Biomedical Engineering
  • Hematology
  • Diagnostic Technologies

Background:

  • Traditional viscoelastic hemostatic assays face limitations including high cost, lack of portability, and scalability issues.
  • Current methods rely on complex biomechanical measurements, hindering widespread clinical adoption.

Purpose of the Study:

  • To develop a novel, cost-effective, and portable method for viscoelastic hemostatic assays using adaptive bubble behavior.
  • To validate the diagnostic accuracy of this new method in a clinical setting.

Main Methods:

  • Utilized self-induced adaptive-bubble behavioral perception for viscoelastic property assessment.
  • Developed an integrated bubble array chip for microassays and reproducible multi-bubble tests.
  • Conducted a prospective clinical study for model development and assay validation.

Main Results:

  • Achieved high diagnostic accuracies: 99.1% for key viscoelastic hemostatic assay indicators (reaction time, kinetics time, alpha angle, maximum amplitude, lysis at 30 min).
  • Demonstrated 100% accuracy in diagnosing hypercoagulation, healthy, and hypocoagulation states.
  • The bubble-based method showed good reproducibility and enabled automated, user-friendly diagnosis.

Conclusions:

  • The adaptive bubble behavior method offers a promising, refreshingly simple alternative to conventional viscoelastic hemostatic assays.
  • This innovation has the potential to address limitations of current assays and meet diverse clinical needs.
  • The user-friendly, automated diagnosis empowers improved clinical decision-making in hemostasis assessment.
