Biomarkers, often referred to as biological markers, are measurable indicators of a biological state or condition. They can be a characteristic that is objectively measured and evaluated as an indicator of normal biological processes, pathogenic processes, or pharmacological responses to a therapeutic intervention. Biomarkers are crucial in various fields, including medicine, environmental science, and toxicology.

In medicine, biomarkers are used to diagnose diseases, monitor disease progression, predict treatment response, and assess the risk of developing certain conditions. Examples include blood glucose levels for diabetes, PSA levels for prostate cancer, and genetic mutations associated with hereditary diseases. The identification and validation of reliable biomarkers are central to personalized medicine, allowing for tailored treatment strategies.

Environmental biomarkers can indicate the presence and impact of pollutants in an ecosystem. For instance, the concentration of certain heavy metals in the tissues of aquatic organisms can serve as a marker for water contamination. Similarly, in toxicology, biomarkers can detect exposure to harmful substances and evaluate the extent of damage to biological systems.

The development of biomarker technology is an ongoing area of research. Advances in genomics, proteomics, metabolomics, and imaging techniques are continually expanding the repertoire of detectable biomarkers. The ultimate goal is to find specific, sensitive, and reproducible indicators that can provide clear and actionable information about health, disease, or environmental status.
