Biomarker 1 article

The biotechnology identity of biomarker comes from measurable biological indicator, which places it within biological measurement concept rather than a general field label. The defining chain runs from diagnostic biomarker through prognostic biomarker to predictive biomarker, while pharmacodynamic biomarker indicates an important use case without changing the entity's core identity. Biomarker is a functional category rather than a particular test; the same biomarker may be measured by different technologies and used for different clinical questions.
