ADAMS has four primary functions addressing key activities of anti-doping operations:

Athlete Whereabouts
The Web-based functionality allows athletes to enter information about their location from anywhere in the world; and those without Web access may designate a representative such as their ADO to enter the information for them. This function also helps stakeholders share whereabouts information, crucial for maximizing the surprise effect and the efficiency of unannounced out-of-competition testing. Athletes can also modify their whereabouts by sending SMS (text) messages.

Information Clearinghouse
The clearinghouse is where data is stored, in particular laboratory results, Therapeutic Use Exemption (TUE) authorizations and anti-doping rule violations. It permits the sharing of information among the relevant organizations and guarantees that anti-doping activities are performed with the highest level of transparency.

Doping Control Platform
The ADAMS doping control database provided to ADOs is an essential tool for managing a doping control program, both in- and out-of-competition. Stakeholders can use ADAMS to plan, coordinate, and order tests, as well as manage test results. Coordination of doping control programs in the ADAMS system helps to avoid duplication in doping controls.

TUE Management
ADAMS allows for online management of TUE requests, as well as online notification of those involved in the process.
