Not sure the equipment that detected it is affected by the scenario you laid out there

The positive test threshold is so low that it's within the margin of error. You're basically getting a result that says 1, +/-1; you can call that a false positive, if you want to be charitable to the group that is making a spectacle of fentanyl at every opportunity, but it sure seems to border on malicious to me.

It absolutely is. Analytical chemistry often requires a trained analyst to be able to correctly interpret results - even then, often the best you can get is "This is consistent with X... but could also by Y or Z or a ton of other things."
