How a biomarker’s usefulness is studied
Accepting a biomarker for one use is not approval of every test measuring it.
Qualification for research has a defined scope.
Accepting a biomarker for one use is not approval of every test measuring it.
An example of scope
FDA explains that its qualification program accepts biomarkers for a specified drug-development context. Qualification does not imply approval or clearance of a diagnostic test, or qualification for clinical practice. This precision matters when a story uses “validated” without saying for what purpose.
Read the proposed decision
On an original reading sheet, write who would use the information, for which decision and with what consequences. Then ask whether the study measured that consequence or only an association. If not measured, leave clinical utility as an open question. An association can be valuable without yet settling the proposed use.
Professional context / Contexto profesional

Evidence / Evidencia
Explanation of qualification-program scope, not a clinical trial of a particular test.
Limitations / Limitaciones
Does not endorse a laboratory, panel or commercial service.
