WADA says the EPO Urine test has shown no false positives, so that would make the percentage zero. (It has, however, shown false negatives). This was based on an emphrical study of 1152 elite athletes.
Ah, there seems to be some confusion here. The 1,152 athletes were used to establish the model used in the blood test. They had nothing to do with the urine test which, as the WADA report on the blood test notes, is the only means of establishing the presence of rhEPO in the body.
The urine test is the one being used to determine an athlete's guilt or innocence.
But we still don't know if and how the urine test was validated to ensure against false positives. There is no mention of any validation study -- let alone a validation study published in a peer-review journal -- in any of the WADA documents, at least as far as I can tell.
