exactly...thats the reason to take a B sample. Scientists like to have duplicate samples....not only in the world of cycling, but in all areas too. Since we are dealing with exceedingly small amounts of a compound, we always have to be concerned with sample integrity. Hence the "B" sample. If "B" comes back with the same unusually high ratio, then it is confirmed to be high. Investigation proceeds forward.... If "B" ratio comes back drastically different, i.e., "normal" then we lean more towards a lab issue. Sadly, that would cloud all results from the lab designed to keep athletes clean.
