Toxicology

The recognition of a possible intoxication and the identification of specific toxicants can be challenging, especially in the absence of historical clues to specific toxicant exposure. Obtaining a comprehensive history that includes possible toxicants in a horse’s environment is critical. The mere presence of a toxicant, however, does not mean that there has been exposure to the compound. Evidence of exposure, occurrence of compatible clinical signs, and possible laboratory testing are necessary components to a toxicologic diagnosis.
