Any Player can be tested for doping control purpose in- and out-of-competition, at any time and at any place, with no advance notice by any Anti-Doping Organization with authority to do so, such as ITTF, a National Anti-Doping Organization (NADO), NPC, IPC or WADA.

In- or Out-of Competition?

For ITTF Table Tennis International Events and Para Table Tennis Table International Events, ie the list of events under ITTF’s jurisdiction, “In-Competition” means the period commencing twelve (12) hours before a Competition in which the Athlete is scheduled to participate through the end of such Competition and the Sample collection process related to such Competition.

By default, “Out-of-Competition” is any period which is not “In-Competition”.

The Doping Control Process

Below are links to a WADA video and leaflet describing what Players need to know from the time of notification for testing until the end of the process:

Whereabouts Information

No-notice, out-of-competition testing is the cornerstone of efficient doping control. Whereabouts information allows doping control officers (DCOs) to find athletes for unannounced out-of-competition tests.

Players are required to submit whereabouts information when they belong to a testing pool.

Thus, ITTF defines pools of top-level players who are required to submit whereabouts information through the WADA online ADAMS system, the Registered Testing Pool (RTP), and the Testing Pool (TP).

Whereas Players in the RTP are subject to the mandatory requirements set out the in the International Standard for Testing and Investigations, including sanctions for whereabouts failures anti-doping rules violations, Players in the TP are required to submit less detailed information, mostly on training and competition activities.

In Table Tennis, for each calendar year, based on the General Ranking List in the preceding December month, the ITTF primarily defines a RTP composed of the best 5 ranked men and women, and a TP composed of the top 5 ranked men and women and the top 5 U21 boys and girls that are not otherwise in the RTP.

In Para Table Tennis, for each calendar year, based on the relating ranking lists of the preceding December month, ITTF primarily defines a TP composed of the 1rst ranked men and women in the 3 most populated standing Classes (Classes 6-10) and 2 most populated sitting classes (Classes 1-5).

In principle, the standard RTP and TP would not include more than 2 players representing the same National Association per category. However ITTF may, at its discretion, include at any time any players in the RTP and TP. Players will be always notified in writing, through their National Association and/or National Paralympic Committee, if they are designated to be part of, or to be removed from a RTP or TP.
