1. The ISL is a mandatory level 2 International Standard developed as part of the World Anti-Doping Code (WADAC). The ISL includes requirements for WADA accreditation of doping laboratories, operating standards for laboratory performance and description of the accreditation process. Its main purpose is to ensure laboratory production of valid test results and evidentiary data. It is also intended to ensure that the accredited laboratories achieve uniform and harmonized results and reporting thereon. The ISL, including all Annexes and Technical Documents, is mandatory for all Signatories to the WADAC. The ISL is therefore not directly applicable to athletes but rather to the signatories to the WADAC.
