Biomarker is a measurable indicator of a biological state. It can be a molecule, a gene, a physiological function, or even a characteristic that can be objectively measured and evaluated. Biomarkers are used in a wide range of applications, including disease diagnosis, prognosis, and monitoring treatment response. They can also be used to assess the risk of developing a certain disease or to understand the underlying biological processes of health and disease.

In the context of medicine, biomarkers are crucial for personalized medicine, allowing for tailored treatments based on an individual's unique biological profile. For example, certain genetic mutations can serve as biomarkers to predict a patient's response to specific cancer therapies. Similarly, levels of certain proteins in the blood can indicate the presence of a disease like heart disease or diabetes, or track its progression.

Beyond human health, biomarkers are also employed in environmental monitoring to assess the impact of pollutants on ecosystems. In agriculture, they can be used to monitor crop health or to detect the presence of specific pathogens. The development and validation of reliable biomarkers are ongoing areas of research, constantly expanding the possibilities for understanding and influencing biological systems.
