Biological assays, also known as bioassays, involve the measurement of an animal or organ’s response to specific substances. These assays are utilized to evaluate the effects of drugs or to quantify hormone levels, among other applications. By observing and analyzing the response of biological systems, bioassays provide valuable insights into the interactions and impacts of various substances.
