Predictive biomarkers are measurable biological indicators that can be used to predict a patient's response to a specific treatment or therapy. These biomarkers can help healthcare providers personalize treatment plans and improve patient outcomes by identifying individuals who are likely to benefit from a particular intervention. Predictive biomarkers are commonly used in oncology and other fields of medicine to guide treatment decisions and optimize patient care. Researchers continue to explore and discover new predictive biomarkers to enhance the efficacy and precision of medical treatments.
