Professor Richard Mellanby was invited to present the recent research findings from the VitDAL at the ACVIM conference this week which is one of the largest veterinary conferences in the world. Prof Mellanby presented an overview of recent work which ranged from case studies describing how measuring vitamin D metabolites guided management of individual cases through to our murine experimental work. It also provided an opportunity for VitDAL to highlight our expanding capacity to measure vitamin D metabolites in samples from veterinary patients.
