Toxicity Testing

toxicity testing
Toxicity testing determines toxicity level and time it takes to see negative effects when exposed to a toxin.

Imperative to the drug and product development process, toxicity testing exposes the toxic effects of products on living organisms. A substances toxicity can be observed through in-vivo and in-vitro tests which establish safe exposure levels. Toxicity testing is performed on many consumer products such as pharmaceuticals, pesticides, food additives, cosmetics, and more.

Toxicology is the science of studying effects and treatments of toxins and poisons and dates back as far as the 1500’s to Paracelsus, a physician and alchemist famously quoted as saying, “All substances are poisons; there is none which is not a poison. The right dose differentiates a poison and a remedy.” Toxicity is the potential of a substance to cause harm or have an adverse effect.

Toxicity testing helps determine the toxicity level as well as the time it takes to see negative effects when exposed to a toxin. Two types of effects are observed, acute effects which occur rapidly from short-term exposure and chronic effects that occur after repeated long-term exposure.

Toxicity tests are performed to generate data about the negative effects on health or the environment. These tests are performed in vitro or outside a living organism on tissues, cell lines, stem cells, etc., or in vivo, using the whole living organism. Toxicological testing is important for the development of new pharmaceutical drugs and for identifying the potential of existing molecules.
