The world of horse race drug testing is constantly evolving. New regulations regarding banned and controlled substances can be found throughout the United States, Europe, Asia and Australia. The need for a reliable and quick SPE method for the determination and separation of a wide variety of drug classes is critical to laboratories certified in this realm of veterinary medicine. In addition to traditional drugs of abuse, horse race drug testing also encompasses drug classes such as bronchodilators, diuretics, antihistamines and non-steroidal anti-inflammatory medications.
