Clinical Biomarker

Meaning

A Clinical Biomarker is a quantifiable biological characteristic, such as a molecule, gene, or physiological measure, that is objectively measured and evaluated as an indicator of normal biological processes, pathogenic processes, or the pharmacological response to a therapeutic intervention. In endocrinology, these are typically circulating hormone concentrations, specific genetic variants, or metabolic protein levels assessed in bodily fluids or tissues. They serve as indispensable, objective tools for accurate disease diagnosis, prognosis assessment, monitoring of treatment efficacy, and identification of individuals at heightened risk.
