Status: question. Rule: atlas-profile-2.0.
3 linked publications; not a count of independent studies.
Missing appraisal does not mean no evidence exists. Inspect the full profile and source relationships in the interactive Atlas.
Historical grade: MODERATE (retained from 22 September 2026; not a completed profile 2.0 assessment).
A biomarker's repeatability sets the floor for detectable change; most are deployed without established repeatability coefficients, so 'change' may be noise.
Consensus acquisition recommendations exist but repeatability across the real installed base is largely unquantified.
Multi-vendor test-retest (coffee-break) studies producing repeatability coefficients and minimal-detectable-change thresholds for each biomarker.
This question comes from selected literature. Confirm that the gap remains open with a current search and mentor review.
