Sample Collection Process

An important piece of any anti-doping program is sample collection or the process of securing an athlete’s blood and/or urine sample, completing paperwork, as well as preparing and shipping the sample to a laboratory accredited by the World Anti-Doping Agency (WADA). USADA is a signatory to the World Anti-Doping Code (Code), and USADA’s sample collection process is fully compliant with the Code and International Standard for Testing & Investigations.

The sample collection process is designed to be a safe process, and as comfortable as possible for athletes, while ensuring that the sample integrity is maintained throughout. The sample collection process is a standard procedure, from notification of the athlete to the shipment of the sample to the laboratory.
