WebDec 4, 2024 · Every biological product such as vaccines, hormones, antibodies, cell therapies, complex therapeutic proteins, and gene therapies all need a bioassay or multiple bioassays to measure biological activity. A bioassay is an interesting combination of science and statistical methods to determine potency or relative potency. WebToxicity can be measured by its effects on the target (organism, organ, tissue or cell). Because individuals typically have different levels of response to the same dose of a toxic substance, a population-level measure of toxicity is often used which relates the probabilities of an outcome for a given individual in a population.
