Horse Racing: 2017 Michigan Medication Testing Change

Horse Racing: 2017 Michigan Medication Testing Change

MGCB has accepted a bid from a new laboratory to drug test horses racing at pari-mutuel tracks in Michigan. The new laboratory, Industrial Laboratories of Wheat Ridge, Colo., is a national leader in testing, expertise, and capabilities. Industrial Laboratories conducts equine drug testing for regulators in Indiana, Minnesota, and West Virginia among others.

With the new testing capabilities, the MGCB will adopt parts of the Association of Racing Commissioners International (ARCI) and the Racing Medication and Testing Consortium’s (RMTC) National Uniform Medication Program (NUMP).

The National Uniform Medication Program in part includes:

  • Laboratory Accreditation – Industrial Laboratories is fully accredited by the RMTC and to ISO standards
  • Penalty Systems ̶ Guidelines the stewards will consider when ruling on medication violations
  • Controlled Therapeutic Substances – A list of medications commonly used to treat illness while horses are in training, which includes thresholds adopted by the overwhelming majority of racing states. With the thresholds, the ARCI and RMTC offer withdrawal guidelines for the listed therapeutic medications.

NUMP withdrawal guidelines are for informational purposes only. They do not constitute a guarantee. Additionally, this guidance is based upon administration of a single medication. The combination of any of these medications or addition of other substances may substantially affect the withdrawal times.


It’s important to note the withdrawal guidelines are for a specific dosage and route of administration. If a different dosage or administration route is used, the time listed in the withdrawal guideline section will not be applicable. It is always best to consult your veterinarian about specific medication withdrawal requirements.
