Abstract

Hair analysis has been evaluated as a retrospective non-invasive diagnostic technique to identify and quantify drug administration and exposure to mycotoxins and plant toxins in horses. The purpose of this review is to describe and discuss in detail the development and application of this technique to equine hair, and to interpret data generated thus far. Particular attention is paid to both extrinsic and intrinsic factors, including pigmentation and hair growth-rates, that impinge on the conduct of hair analysis and which can be potential sources of error. In the absence of research specific to the horse, this review draws upon comparative data in humans and other species, on hair analysis and potential toxins of particular relevance to the horse.
