The PADLS Toxicology Laboratory at New Bolton Center provides a full veterinary diagnostic toxicology service to the Commonwealth of Pennsylvania. The Laboratory provides:

• A broad spectrum of analyses for both natural and man-made toxicants including mycotoxins, drugs, environmental contaminants, insecticides, rodenticides, anions, and metals performed on a variety of sample matrices.

• A broad spectrum of analyses for nutritionally relevant compounds including metals (selenium, copper, zinc, etc.)and vitamin E in animal samples.

• Case consultation.

• Assistance in field investigation of possible toxicoses.

• An active method development program for new or emerging toxicants, markers of nutritional status and chemical food contaminants.

Description of Research Expertise
