Much of the work carried out by DTT is in support of the National Toxicology Program (NTP), an interagency partnership of the Food and Drug Administration, National Institute for Occupational Safety and Health, and NIEHS.
Office of Program Operations
The Chemistry and ADME (absorption, distribution, metabolism, excretion) Resources Group (CARG) designs and directs the work of contract study laboratories conducting chemistry activities and ADME and toxicokinetic studies. CARG coordinates with other Offices and Branches in DTT so that the timelines for these activities efficiently augment other programmatic activities, ensuring that the needs of the DTT are met, the best available methods and techniques are used, and the results are appropriately and accurately described and reported.
