Good find. So LA was tested five times during the TdS that year, including three times for EPO. All three tests were reported negative, but two were further described as strongly suspicious. At that time, and at that lab, 80% of the bands had to be in the basic area for a test to be considered positive. One of LA's tests exhibited 75% basic, which is in the strongly suspicious area, whereas another was 70%, just below the cutoff for strongly suspicious (though it was still described as such in the report).
Since LA's confession, the whole significance of this report, of course, is whether it supports the charge that UCI covered up a positive. UCI is using this report to argue that it shows that it didn't, since there was no official positive. Based on these documents, it's pretty hard to argue against them.
However, the article also notes that LA was tested ten times at the TDF that year, five of them for EPO, all of them of course reported at the time as negative. The most suspicious of his samples registered at 72, though apparently the French used a different criterion and this was not reported as strongly suspicious. Taken together, though, this shows that at least 3/8 EPO tests LA had at that time were strongly suspicious, by the Swiss standards, including the one at the lower bounds of the criterion.
Though it doesn't matter now, results like this would be pretty strong evidence of EPO use. I'm pretty sure a large majority of samples with over 70% of the bands in the basic area are positive, but are scored negative to avoid occasional false positives. The odds of getting 3/8 tests like this from a clean rider would have to be pretty low. UCI certainly should have been suspicious of LA, but without a legitimate positive, they couldn't have sanctioned him.
