In vivo evaluation is a research area that involves the testing and evaluation of biological processes, functions, or responses within a living organism. This type of research often involves studying the effects of drugs, treatments, or interventions on animals or human subjects to understand their efficacy, safety, and mechanism of action. In vivo evaluations can provide valuable insights into how substances interact with living organisms and help researchers make informed decisions about potential therapeutic strategies. This research area is crucial for advancing our understanding of disease physiology, drug development, and personalized medicine.
