The global in-vitro toxicology testing market size valued at USD 8.92 billion in 2020 and expected to reach USD 18.03 billion by 2027, growing at a CAGR of 11.0% during forecast period 2021 to 2027. The technique of determining the potential for dangerous compounds is known as in-vitro toxicity testing. It's also utilised to check for the presence of specific hazardous properties in useful substances like agricultural chemicals, therapeutic medications, and food additives. Toxicity testing is required in the development of new compounds since detecting possible toxicity earlier in the drug development process can save time and money, as well as reduce the risk of late-stage failure. In vitro toxicology testing is used to determine whether hazardous substances or poisons are present in an organism's cells. In vitro toxicology testing is an analysis of effects of the toxic substances on cultured mammalian cells or bacteria. These techniques are primarily employed for identification of potential hazardous chemicals in order to confirm the certain toxic properties at early development stages of therapeutic drugs. In vitro toxicology testing market is highly fragmented due to presence of many market players, expected to offer lucrative growth during the forecast period. Market players are concentrated on development of new software solutions, introduction of innovative technologies, enhancing in silico simulation methods in toxicological profiling. Companies are adopting various growth strategies such as new product launches, acquisitions and mergers in order to enhance the product portfolio and market presence.
