Vino positive!!!

[Eden]

So did Landis actually test positive, and were his levels just below the threshold for an illegal substance?

Landis tested as having abnormal testosterone to epitestoterone ratios
Now any use of outside testosterone would be banned, but the tests for this are tricky and it is a naturally occuring substance in the body. Though I haven't read all of the defense I believe that there are some arguments for suspect testing procedures in there. The mass spectrometer (sp?) test that proved the T was not natural sounds like a fairly hard one to counter though.

I think you may be remembering a Lance Armstrong test - it was for a very low level of a steroid, under the threshold for a positive doping test (as this is also a substance that naturally occurs in the body) and was also explained by possible contamination by a legal topical saddle sore cream.

The test for homologous blood doping is also tricky and actually quite subjective, so lets wait for the testing of the B sample (and Vinokurov himself has requested B sample testing) before we make any condemnations.
