Biofluid analysis is a research area that involves the study of various biological fluids in the body, such as blood, urine, saliva, and cerebrospinal fluid. This analysis aims to understand the composition, properties, and functions of these fluids in health and disease. Researchers in this field use various techniques, such as mass spectrometry, chromatography, and immunoassays, to identify and measure the presence of biomarkers, metabolites, proteins, and other molecules in biofluids. Biofluid analysis has applications in disease diagnosis, monitoring treatment efficacy, and discovering new therapeutic targets. It is also used in fields such as personalized medicine, clinical research, and drug development. Overall, biofluid analysis plays a crucial role in advancing our understanding of human biology and improving healthcare outcomes.
