March 19 - Brazilian authorities need to "act quickly" and "take the opportunity" to get their doping control laboratory accredited in time for the Rio 2016 Olympics and Paralympics.
The laboratory in the Olympic host city was revoked of its accreditation in August last year because of "repeated failures".
Speaking exclusively to insidethegames, World Anti-Doping Agency director general David Howman said: "Rio is being given every opportunity to get fast-tracked and accredited.
"They need to take that opportunity and do it quickly."
When he was asked what the deadline was, Howman responded: "Yesterday."
Because the laboratory will not be ready in time for this summer's World Cup, football governing body FIFA is planning to fly around 900 samples to Lausanne in Switzerland for testing.
But Howman said a 24-hour process becoming a "36 or 30-hour process" was of no concern.
The Federal University of Rio de Janeiro doping control laboratory, also known as LADETEC, is currently adding to its facility.
"They're looking to open their new building so they can do it all under one roof, which I can understand," explained Howman, who spoke earlier at the Tackling Doping in Sport conference here.
"If it was me, I'd be running around to get it done."
