Is a biomarker always a chemical?

No. A biomarker can be a molecule, a gene, a specific cell, an imaging characteristic (like on a scan), or even a pattern of electrical activity.

What's the difference between a biomarker and a symptom?

A symptom is subjective and reported by the patient (e.g., pain, fatigue). A biomarker is an objective, measurable indicator detected through tests.

Can a single test measure multiple biomarkers?

Yes. Modern diagnostic panels or 'omics' technologies (like genomics, proteomics) are designed to measure many biomarkers simultaneously to create a more comprehensive profile.

Are all biomarkers reliable?

No. A useful biomarker must be validated for its specific purpose (diagnostic, prognostic, etc.). It must be sensitive (correctly identifies positives) and specific (correctly identifies negatives) for the condition in question.

Is “biomarker” formal?

Biomarker is usually technical/academic/scientific in register.
