What does this research mean for the field?

The clinical translation of activity-based protease assays depends primarily on standardized analytical validation, harmonization, and regulatory conformity, which can be guided by a newly proposed minimum validation-and-reporting framework. Novelty: ClaimNovelty.SYNTHESIS. Consensus alignment: ConsensusAlignment.NEUTRAL.

Review outlines analytical validation and quality control standards for catalytic protease assays, highlighting essential steps for clinical translation.

Key Points

To define the analytical validation, harmonization, and quality assurance framework required to transition catalytic protease assays from research tools into clinical diagnostic tests.
Examined the adaptation of clinical chemistry metrological frameworks to kinetic, matrix-dependent protease activity measurements across various reporter formats.
Evaluated key analytical parameters including analytical specificity, precision, limits of detection and quantification, linearity, trueness, robustness, and biological matrix interference.
Identified critical gaps impeding translation, notably the absence of standardized units of proteolytic activity, reference materials, and external quality assessment programs.
Proposed a phased minimum validation-and-reporting framework checklist aligned with current United States and European in vitro diagnostic regulatory standards.
