Because biomarkers are used so often in scientific and clinical research, as well as in clinical practise, it is now nearly taken for granted that they will be used as primary endpoints in clinical studies. The use of medical signs in clinical practise is as old as medicine itself, and biomarkers are simply the most objective, quantifiable medical indicators that current laboratory science enables us to assess consistently across time.

It is a biological trait that may be molecular, anatomical, physiological, or biochemical in nature. These qualities are measurable and objectively evaluable.

A biomarker is a physical characteristic or detectable physiologically induced alteration in the body that is connected to a disease or a specific health issue.
