I am a union representative on my job and am dealing with a case involving a positive amphetamine test.  The donor tested positive for amphetamines in a non-DOT urine test.  There was a split sample, and he has just asked for sample B to be tested.  My question is this: If the original drug test was conducted on June 1st 2009, and the split sample is just now being sent for testing, how much of the drug/metabolite will deteriorate during storage, if any?  Thanks.
