All equine post-race testing in Kentucky is performed to the standards established by the Thoroughbred Owners and Breeders Association's North American Graded Stakes Committee—often referred to as 'super testing'. We make no distinction between bottom level claiming races and graded stakes as we believe that integrity is not associated with a specific class of race. The dollar wagered on a $5,000 claiming race is worth no less than the dollar wagered on the Kentucky Derby.
I apologize for the delay in my reply. Please do not hesitate to contact me if I can be of further assistance.
