The Rio de Janeiro anti-doping laboratory which was to be used for the 2014 World Cup and 2016 Olympics in Brazil has had its right to test samples revoked.
The World Anti Doping Agency says it will revoke its status on September 25th for failing to meet international standards.
WADA carries out regular quality controls on its 35 laboratories worldwide to ensure that they are not falsely declaring positive samples and they are reporting abnormal results.
The Brazilian laboratory previously had its accreditation suspended for nine months in 2012 before being reinstated.
