Afin déviter tout doute, la Directive 5 (i) des ''Directions for Security 2017'' a été amendée comme suit :
5. (i) Elective tests may be requested at the expense of the Stable concerned. Completed application forms must be submitted to the Chief Security Officer such that results are available before declarations. Applications for elective tests will close at 9 a.m. on Tuesdays for Saturday meetings and at 9 a.m. on Wednesdays for Sunday meetings.
