Beijing test lab suspended

China's anti-doping authority said it is trying to solve the problems that caused the suspension of its testing laboratory and denied that the recent positive drug tests of Chinese swimmers had anything to do with it.

The World Anti-Doping Agency announced on its website on Friday that it has suspended its accreditation of the National Anti-Doping Laboratory in Beijing for a maximum of four months.

The suspension, to take effect immediately, means the lab has to stop carrying out any WADA-related anti-doping activities, including all analyses of urine and blood samples.
