bioassay

A bioassay is a scientific test used to measure the effects of a substance—such as a drug or chemical—on living organisms. By observing how these organisms respond, researchers can determine the potency, effectiveness, or toxicity of the substance being tested. For example, a bioassay might involve giving a specific dosage of a medication to a group of animals and then monitoring their health and reactions. The results help scientists understand how substances work in biological systems and guide the development of new therapies or safety assessments for existing products.
