WADA bans world's biggest lab
The World Anti-Doping Agency (WADA) has partially suspended its accreditation of the UCLA Olympic lab for three months.
WADA said in a statement Monday the lab's procedures were not in keeping with "best practice".
WADA says the UCLA Olympic Analytical Laboratory can continue its normal anti-doping testing during the suspension, but must get a second opinion from another WADA-accredited lab before reporting certain findings.
UCLA was notified of the decision last week and has 21 days to appeal.
The lab says it is the world's largest WADA-accredited drug-testing facility and analyses 45,000 urine specimens a year. The lab did not immediately return requests for comment.
