Protecting the Right to Enjoy Doping-Free Sport

Sample Collection Procedures for Minors

You are considered to be a minor if you are under the age of 18.

Minors will be tested in the same way as other athletes, except for a few modifications to the sample collection process.


If you are selected for doping control you must be notified in the presence of another adult. The other adult could be: another member of Doping Control Personnel, a representative from a National Governing Body, a coach or manager.

As with all athletes, you have a right to have a representative present with you throughout the testing process, and we recommend that you take that opportunity, particularly if this is your first test.

Your representative must be able to be present for the duration that you are in the Doping Control Station, and sometimes this can take some time. If you are tested at a competition, the Doping Control Station might be in an area that requires accreditation, so you may need to select a representative who has this.

If you decide not to have a representative, two members of the Doping Control Personnel will be present throughout the testing process.

Urine Sample Collection Process

When you provide the sample you will be observed by one Doping Control Officer (DCO) or Witnessing Chaperone. This DCO will be observed by another member of the Doping Control Team (a Second Observer) and your representative (if you have requested one). You will not be directly observed by the Second Observer or your representative unless you request them to do so.

Before giving the sample the athlete will be asked to either wear gloves or wash and dry their hands.
The athlete will be asked to remove enough clothing so that the DCO can directly observe the passing of the urine from the body into the collection vessel. This is necessary to avoid any possibility or suggestion of manipulation.

As much urine as possible should be passed (at least 90mls) into the vessel unless otherwise advised by the DCO.

If the DCO is concerned about the integrity of the sample or the behaviour of the athlete, an additional sample will be requested. Athletes must comply with this request or they could be liable for an Anti-Doping Rule Violation.

Chaperones and DCOs should never physically touch a minor, or any athlete, during the sample-collection procedures.

Blood Collection Process

If you are selected for a blood test, you must be accompanied by a representative throughout the sample-collection procedures.

Only a person trained in the collection of blood will be able to perform the blood collection procedure.

The Blood Control Officer (BCO) shall assess the most suitable vein for sample collection and clean the site. They will then unseal the hypodermic needle and attach the vaccutainers (self-sealing secure containers) and withdraw blood to fill the required number of tubes. No more than three attempts will be made per session.
