Chromogenic substrate methods, established in diagnostics for over 30 years, are seeing renewed development. New specific chromogenic assays are emerging for novel anticoagulants and global assays, potentially enhancing clinical diagnostics.

Area of Science:

  • Clinical Chemistry
  • Hematology
  • Biochemistry

Background:

  • Chromogenic peptide substrates have been available for over three decades.
  • Initial adoption in coagulation and fibrinolysis diagnostics was slower than anticipated.
  • These methods are now standard for quantifying analytes like antithrombin, FVIII, protein C, plasminogen, plasmin inhibitor, heparins, and pentasaccharides.

Purpose of the Study:

  • To review the established and emerging applications of chromogenic substrate methods in diagnostics.
  • To highlight the impact of novel anticoagulant therapies on the development of new chromogenic assays.
  • To discuss the potential clinical significance of global chromogenic assays for thrombin generation and the protein C pathway.

Main Methods:

  • Review of established chromogenic assays for routine diagnostic analytes.

  • Analysis of newly developed chromogenic methods targeting direct thrombin and factor Xa inhibitors.
  • Exploration of research into global chromogenic assays for complex hemostatic pathways.

    • Main Results:

    • Chromogenic methods are well-established for numerous coagulation and fibrinolysis analytes.
    • New specific chromogenic assays are being developed in response to novel anticoagulant drugs.
    • Global chromogenic assays for thrombin generation and the protein C pathway show clinical promise.

    Conclusions:

    • Chromogenic substrate technology remains a valuable tool in hemostasis diagnostics.
    • The development of novel chromogenic assays is driven by advancements in anticoagulant therapy.
    • Emerging global chromogenic assays may become important in routine clinical practice.
