Most products are designed for direct use by humans, but may contain chemicals and materials toxic to humans. Traditional toxicity screening has been deficient for a variety of reasons, including inaccurate and irrelevant rodent studies. An LD50 is rats is a crude measure, and often misleading. Toxicology studies on actual human tissues has greater relevance, and now that CAP organs reproduce important aspects of organ function, improved toxicological evaluations can be conducted. Our panel of organ models also provides advanced data on effects in multiple organs. Human culture models are in the processs of replacing older toxicological methods, making it expedient to switch to CAP organ toxicological testing.
