It's not for sure. It's an A sample. A samples are very fuzzy and really aren't all that acurate. If you remember Lance Armstrong tested positive for high testosterone levels in his A sample but it never went reported. Then his B sample cleared him of any wrongdoing. Years later a French newspaper found the positive A sample and tried to use it as evidence to prove he doped. The B sample is what counts. Landis is disputing the positive test. EVERY SINGLE time a rider has disputed a positive A sample, the B sample has came up clean. Let's not jump to any conclusions just yet.
