Athlete Test History

All samples collected from athletes conducted for USADA’s Olympic, Paralympic, Pan American, and Parapan American testing programs, as well as any for-pay client testing for which USADA is the testing and/or results management authority.

Please note that the number of samples USADA has collected is typically not the number of test sessions an individual athlete has been selected for during a given period, as multiple samples (e.g., blood, urine, dried blood spot) are often collected during a test session. Thus, the number of samples collected typically does not equate to the number of times an athlete has been selected for an in-competition or out-of-competition test session with a USADA Doping Control Officer.

A search result may include:

This search will not include:

Data that is more than 10 years old

This resource is intended to show the total number of samples USADA has collected from an individual athlete and is not an accurate representation of USADA’s total testing sessions or the total number of anti-doping tests an athlete will undergo because it does not include data from other organizations with testing jurisdiction (e.g., International Federations, major games organizers). For questions or clarifications, please contact media@USADA.org.

This database is updated weekly.

USADA regularly audits its testing data to ensure accuracy and transparency, and this may occasionally cause fluctuations in total testing numbers for some athletes. Please note that testing activity was also temporarily reduced from March – August 2020 due to the COVID-19 pandemic.

As noted, the number of samples USADA has collected is typically not the number of test sessions an individual athlete has been selected for during a given period, as multiple samples (e.g., blood, urine, dried blood spot) are often collected during a test session. Thus, the number of samples collected typically does not equate to the number of times an athlete has been selected for an in-competition or out-of-competition test session with a USADA Doping Control Officer. Please see above for more information about what is and is not represented in this database.
