Blood Sample Collection PRocess
Athletes who compete in events sanctioned by, are members or license holders of a National Governing Body, or who fall under the USADA testing jurisdiction as defined in the USADA Protocol for Olympic and Paralympic Movement Testing, are subject to blood testing. Blood testing allows for the detection of additional substances that in some cases may not be able to be detected in urine. Additionally, blood samples allow for the use of longitudinal data collection, often called the athlete biological passport. Longitudinal data collection monitors certain bio markers over time to detect the use of performance-enhancing substances and/or methods.

Athletes can be selected for testing at anytime and at any location.
When USADA develops its plan to allocate testing resources, a number of considerations factor into the approach to testing athletes. They can include the physical demands of the sport, the history of doping in the sport, training periods and the competition calendar, and many other key considerations. When athletes are selected for testing, they may be required to provide a urine sample, a blood sample, or both. Athletes are not selected for testing by the Doping Control Officers.
Athletes selected for an in-competition test may be selected based on rules that the international federation or a local organizing committee has established. This could include a place finish within the competition as well as being randomly selected or target tested. Click here for more information on test distribution planning.
