What is the International Standard for Testing and Investigations?

The International Standard for Testing and Investigations (ISTI) is one of the mandatory International Standards of the world anti-doping system. The International Standards set out the technical detail of implementing the Code, and compliance with them is mandatory for all Signatories to the Code. This Standard determines the procedure for test planning, notification of the athlete, sample collection, sample storage and transport, as well as the gathering of information and the conduct of investigations.

Who this document matters to

A procedural challenge to the sample collection procedure is one of the most common lines of defence in doping cases, and its basis is this text: from the manner of notification and chaperoning of the athlete to the chain of custody of the sample. The rules on whereabouts information are also set out in detail in this document.

Each case is governed by the edition of this Standard that was in force at the time of the events; for that reason earlier editions are kept available on this page. The official text is published in English and French and, in the event of a conflict, the English text prevails.
