MONTREAL (AP) — The World Anti-Doping Agency has reinstated the drug-testing lab in Rio de Janeiro, the host city of the 2016 Olympics.

The lab had been suspended since Jan. 18 from conducting a type of testing called isotope ratio mass spectometry, or IRMS. WADA suspended the lab after it mistakenly accused a Brazilian beach volleyball player of using testosterone.

WADA said Friday that it had monitored the lab and ensured that "proper corrective actions had been implemented."

The Rio lab is expected to test samples from the 2014 World Cup and 2016 Rio Olympics.
