The A sample was tested in 1999 but was not frozen.
Drug tests are divided into an A sample and a B sample for testing.
The results of their A samples were confirmed by positive B samples.
If the A sample is positive, the B is tested to confirm the initial result.
Another unusual aspect of the case is the disclosure that the first test - the A sample - was positive.
The A samples, which were destroyed in 1999, must also be tested for a valid result, Bisceglia said.
The laboratory tests the A sample.
Last week, the anti-doping agency said it had informed athletes of positive A samples.
For these assessments, the A sample is the operational (national main and/or state) assessment.
I am kind of surprised that five days after the fact they are talking about the A sample without the B sample.
