The laboratory received a four-month suspension beginning from Thursday, the China Anti-Doping Agency said in a statement on its website on Friday. It said it would make changes and resume testing after obtaining WADA clearance.
An official who answered the phone at the China Anti-Doping Agency said the laboratory planned to make a further statement through China's official Xinhua News Agency.
WADA said on Friday that it had suspended the laboratory after finding that it had failed to comply with international standards, without giving further details.
