If this framework were incorporated into the FDA's developing "evidence-based regulatory science" approach, regulatory agencies could be explicit on what an appropriate level of evidence (taking into consideration different populations, comparator tests, and outcomes) might be for a given assay and what constitutes a similar enough (vs. new/different) assay.
