Timothy Garrett, Ph.D., associate professor of the UF Department of Pathology, Immunology and Laboratory Medicine, led a study examining the consistency and potency of insulin purchased at U.S. retail pharmacies. The researchers found that all human and analog insulins measured contained the expected quantity of active insulin. Other UF Diabetes Institute members on the research team were Michael Haller, M.D., professor and chief of the Division of Pediatric Endocrinology in the UF College of Medicine, and Mark Atkinson, Ph.D., director of the UF Diabetes Institute.
