Study programs tailored to regulatory requirements
Labcorp has been working with global regulators and scientific bodies on ED testing for many years. From the outset it is important to understand the science and regulation relevant to your substance, to optimize its regulatory journey. Our study directors and regulatory experts combine their expert insight and knowledge to advise on the optimum approach. That may mean leveraging existing data and QSARs to make weight of evidence arguments or it may require a new study program for your substance. Our dedicated technical team ensure any studies run efficiently and to the necessary standards, and our analytical chemists deliver verifiably results. This is then wrapped into a final dossier with our team supporting your final submission. Beyond submission, our regulatory team can support you by engaging with regulators to advocate for your substance.

Conceptual level 1 testing capabilities
QSAR modelling and read-across form a vital part of weight of evidence arguments for endocrine disruptor endpoints. They also signal appropriate in vitro and in vivo testing strategies. Data-driven insights are key to the successful use of QSAR model predictions. You can rely on our expertise and experience in leveraging model predictions in your submissions.
