The accreditation of the anti-doping laboratory in 2016 Olympic host city Rio de Janeiro has been suspended, the World Anti-Doping Agency said Friday.
The suspension prohibits the lab from carrying out any WADA-related anti-doping activities and took effect on Thursday.
It's the second action against the lab in two years. The facility was barred from conducting isotope ratio mass spectrometry (IRMS) testing -- used to measure testosterone levels -- from January to October of last year.
WADA did not specify what standards the lab has failed to meet to warrant the latest suspension, but said a "further decision regarding possible revocation of the laboratory's accreditation" would be made by the global anti-doping body's executive committee.
The lab, one of 35 worldwide with WADA accreditation, can appeal the suspension via the Court of Arbitration for Sport.
