The Horseracing Integrity & Welfare Unit (HIWU) reminds horsemen and veterinarians that Covered Horses are subject to testing at any time, including following routine timed workouts (Post-Work testing). Testing following workouts is not limited to Vets’ List workouts.
Please note that Post-Work samples are not collected after all routine timed workouts. Trainers will be notified of selection, and sampling will be performed, within one hour of the completion of the workout.
The following substances are prohibited in Post-Work samples:
All other Controlled Medications, including furosemide, are permitted to be present in a Post-Work sample, regardless of the horse’s age or class.
Horsemen and their veterinarians are encouraged to consult the published Detection Times when considering treatments in advance of a routine timed workout.
More information about the differences in testing and procedures between routine timed workouts and Vets’ List workouts can be found here.
