Biomarker discovery is the process of identifying biological markers, or biomarkers, that can indicate the presence or progression of a disease. These markers can be found in various biological samples, such as blood, urine, or tissue, and help researchers understand how diseases develop and respond to treatments. By pinpointing specific biomarkers, scientists can create more targeted therapies and improve patient outcomes. The discovery of biomarkers often involves advanced techniques like genomics, proteomics, and metabolomics. These methods analyze the molecules in our bodies to find patterns that correlate with specific health conditions. Ultimately, biomarker discovery plays a crucial role in personalized medicine, allowing for tailored treatments based on individual patient profiles.
