Biomarkers are objective, measurable indicators of a biological or pathological process that can be used to assess the efficacy of a therapeutic intervention.

Biomarkers can be classified into four main categories: genetic, biochemical, cellular, and imaging biomarkers.

Biomarkers are important tools in clinical research and practice, as they can provide valuable information on disease progression, response to therapy, and prognosis. In addition, biomarkers can be used to monitor the safety of new drugs and to identify potential drug targets.

There are many different types of biomarkers, each with its own advantages and disadvantages. The choice of a biomarker depends on the specific research question being asked. For example, genetic markers can be used to identify individuals at risk for a particular disease, while biochemical markers can be used to monitor the progress of a disease.

The use of biomarkers is constantly evolving, and new markers are being discovered all the time. As our understanding of the biology of disease increases, so too does our ability to identify and utilize new biomarkers.

Biomarkers play a vital role in clinical research and practice and will continue to do so as our understanding of disease biology increases.
