Division of Residue Chemistry (DRC)
The Division of Residue Chemistry is responsible for the development and evaluation of analytical methods for drug residues in animal tissues, fluids, and feeds. These methods are used in Agency regulatory programs and in the conduct of research studies. The Division conducts metabolism and pharmacokinetic studies that help CVM improve drug availability for minor uses and minor species. The research also aids Center regulatory scientists by developing better models for drug bioavailability and fate and disposition. The Division also is responsible for the review of drug residue diagnostic tests (screening tests). These evaluations determine if the products are accurately labeled and suitable for use by industry and regulators for testing animal-derived foods such as milk.
