The United States Anti-Doping Agency (Usada) says a new self-administered doping test could help protect clean athletes, as the agency tries to ensure no one gets a "free pass" from reduced testing during the Covid-19 pandemic.

Athletes were able to administer the blood and urine tests themselves while being monitored live by a doping control officer via FaceTime or Zoom in the voluntary pilot programme, Usada said.
