Biomarker discovery

Definition

Biomarker discovery refers to the process of identifying biological markers that indicate a particular disease or health condition. These markers can be proteins, genes, or other molecules found in the body and are crucial for diagnosis, prognosis, and treatment decisions. Through advanced techniques, researchers can analyze vast amounts of data to find these biomarkers, leading to personalized medicine and better patient outcomes.
