The 2003 test results were supposed to remain anonymous and the samples destroyed. However, a coded master list of 104 players was seized during the BALCO investigation, turning up in a 2004 federal raid on Comprehensive Drug Testing's facility in Long Beach, California. A month later, the physical samples were seized by federal agents raiding Quest Diagnostics in Las Vegas, Nevada. The list of the 104 positive-testing players was released to the Major League Baseball Players Association (MLBPA) in 2004. The players' union later said that the 104 positive samples were in the process of being destroyed when they were subpoenaed by federal authorities in November 2003, making continued destruction "improper."
