Irish Horseracing Board

    The Irish Horseracing Regulatory Board initiated an Elective Testing process, which offers an analytical service to Trainers/Handlers that wish to establish if medication, given during essential veterinary treatment, has cleared from the animal’s system prior to racing. Furthermore, this service can be utilised by trainers if there is a suspected case of cross contamination/inadvertent medication which is causing concern.


    Elective Testing is available to licenced Trainers/Handlers only and is conducted upon receipt of an official request form being submitted. The cost of the sampling kit and the laboratory fee currently stands at €306 including VAT. This fee is at the Trainers/Handlers own expense and must be settled directly from their Horse Racing Ireland Account. Any transport/courier costs incurred, if applicable, will be invoiced separately by the IHRB Accounts Department.


    Any Trainer/Handler wishing to avail of an Elective Test should contact the IHRBs Anti-Doping Department on 045-445 600 and request an Elective Test Sample Submission Form. Each section of the form should be completed and returned to the IHRB Anti-Doping team via fax (045) 445 601 or email [email protected].


Elective Sampling Procedure

Elective Sampling Procedure
  • Following the request form being received by the IHRB, a urine sampling kit can be collected from the IHRB office or from the team at a race meeting.
  • The urine sample for analysis must be a minimum of 100 millilitres.
  • Urine must be collected in a clean, leak-proof container. Thoroughly washing hands prior to sample collection is essential and wearing disposable latex gloves during the collection process is advised. Lining the collection container with an unused polythene bag is a good way to minimise the risk of contaminating the sample.
  • The sample will be analysed only for the named drug and/or its metabolites.
  • Quantitative measurement of threshold substances is not included in the standard Elective Testing service because of the time constraints of this procedure. The laboratory report will be based on the results of a single analysis only. A full, unequivocal confirmatory analysis will not be carried out. The results and cost of the test relate only to the named drug and apply only to the sample received.
  • Sample drop off should be arranged via the IHRB Veterinary Department and, to avoid incurring transport costs to the laboratory, every effort will be made to arrange drop off at a scheduled race meeting to allow the elective sample to be transported with a pre-scheduled courier.
  • Results are known within four working days of the laboratory’s receipt of the sample. Results are reported to the IHRB, who communicate with the Trainer.
