Biological Markers

Meaning

Biological markers, or biomarkers, are objectively measurable indicators of normal biological processes, pathogenic processes, or pharmacologic responses to a therapeutic intervention. In clinical practice, these molecules, genes, or physiological characteristics are quantifiable tools used to assess an individual’s health status, disease risk, or the efficacy of treatment. Examples include specific hormone levels, genetic variants, or blood pressure readings that correlate with underlying physiological states.
