Biomarkers are important tools for medical research, diagnosis, and patient care. They are measurable indicators of a biological process, disease, or response to treatment. The 10 most commonly established biomarkers include C-reactive protein, cholesterol, albumin, uric acid, total cholesterol, HDL cholesterol, creatinine, glucose, hemoglobin A1C, and white blood cell count. These biomarkers are used to assess overall health, predict disease risk, diagnosis, and monitor treatments. They are also used to measure the body’s response to different treatments, which can help physicians determine the most effective course of action. In addition to these established biomarkers, new biomarkers are continually being discovered and studied for their potential use in medical research and patient care.
