International Standard for Laboratories (ISL)

The International Standard for Laboratories (ISL) sets out the requirements to be followed by WADA-Accredited and WADA-Approved Laboratories for the Athlete Biological Passport (ABP) that wish to demonstrate that they are technically competent, operate within an effective Management System, and are able to produce forensically valid results. The ISL includes, inter alia, requirements for obtaining and maintaining WADA laboratory accreditation and WADA laboratory approval for the ABP, operating standards for the performance of Laboratories and WADA-Approved Laboratories for the ABP and a description of the accreditation and approval processes.

To complement the ISL, WADA also publishes specific technical requirements in a Technical Document or Technical Letter. WADA may also provide laboratories, WADA-Approved Laboratories for the ABP and other stakeholders with specific technical guidance and advice in the form of Laboratory Guidelines or Technical Notes.

The current version of the ISL went into force on 1 January 2021.
