Are they taken from the same sample and just tested at different labs? Are they different samples?

Not 100% sure but I think what they do is take your urine or blood sample and split it in half. Send off the "A" half, if negative for everything, no worries. If positive for something, they then send of the B sample to confirm the first positive. Probably done because these tests are not cheap so to double test each sample would be cost prohibitive.
You're right.look271

It is also done to ensure accuracy and to help eliminate false-positives. If the second test comes back negative, they are considered negative.
How they do it.Sherpa23

A and B samples are from one peeing. When you get called for drug testing, you go to the controls. The two (always more than one) doctors call you and you have to pick one testing kit from three to seven kits. You pick and they ask you to inspect the seals to make sure they have not been tampered with and to give your approval. The doc's do the same. This inspection happens several more times throughout the procedure. The docs open the kit and pull out a cup that is sealed and you do the inspection again and give your approval. Then you go into the bathroom and pee in the cup while one doctor watches. Then you go back into the other room and two sealed medical containers are pulled from the kit - one marked "A" and on marked "B". Inspection on A and you pour enough into "A" until it reaches the mark. You then seal it and give your approval and give it to the doctors. Then repeat process on "B". Then you seal it all up and pack it. Again, you must give your approval. Then you leave and if you are clean, you don't hear anything again. The whole thing takes almost 45 minutes of things are going smoothly but it can take up to two hours. The "A" is tested and if something comes up, they test the "B" to make sure that it was not a contaminated sample. Yes, I have done it several times. Every top finisher at a World Cup or World Championship has to do it and certain places in other UCI sanctioned races.
