An important centerpiece of USADA's anti-doping efforts is sample collection, also known as doping control. This section explains the sample collection process that athletes chosen for doping control will undergo, including both urine and blood testing.

The sample collection process is designed to be a safe process, and as comfortable as possible for athletes, while ensuring that maximum 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.
