Small Animal Expertise & Technology

Minimizing variation within PBI research efforts is critical for generating interpretable data. Our team of scientists, small animal surgeons and animal care staff is trained on industry-leading surgical, instrumentation and animal husbandry techniques. Inter- and intra-operator variance is monitored to ensure reproducibility of data. Multiple quality control measures are captured and evaluated across all aspects of research project execution, giving justification and confidence in all data provided. Internal self-policing systems keep our error rate at an extraordinarily low level.
