Biomarker analysis is a field of research that focuses on identifying and measuring specific biological indicators, or biomarkers, that can be used to assess physiological or pathological processes in various organisms. These biomarkers can include proteins, genes, hormones, metabolites, or other molecules that are indicative of a particular disease or condition. Biomarker analysis is a key component of personalized medicine, as it can help clinicians diagnose diseases, monitor treatment efficacy, and predict patient outcomes. Researchers in this field often use sophisticated techniques such as mass spectrometry, genomic sequencing, and immunoassays to detect and quantify biomarkers in biological samples. Overall, biomarker analysis plays a critical role in advancing our understanding of disease mechanisms and improving patient care.
