Elective Testing and Detection Times
The IHRB offers an elective analytical service to Trainers and Handlers.
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.
