Detecting coffee spiked with xanax?

Can xanax dissolved in coffee be detected by a regular urine test? There's some background information on the question inside.

I should note that this question is mostly hypothetical. The acquaintance who posed it to me tends to be...an unreliable narrator, at times. That said:
An acquaintance of mine says that his friend -- who used to use xanax, but detoxed off it some time ago -- called him a few days ago, saying she was feeling a bit weird and loopy. She asked if he could test her for xanax, and came up positive. She suspects spiking of the office coffee.
Here's what he asked me, and what I'm asking: would it be possible, using an ordinary urine test, to determine whether the coffee is, indeed, spiked?
My thinking is that these tests screen for *metabolites*, i.e. the resulting chemical after your body is done processing the drug, rather than the drug itself. However, I'm not sure of this; perhaps some amount of the drug goes into urine unprocessed, and the normal tests *do* detect straight xanax.
So, does anyone have more definitive information on these tests that would clarify whether testing the coffee would work?
[I told this guy that the whole story sounds unlikely to me -- but that if any of it is true, a very serious crime is being committed and authorities should be involved (and they would do proper lab tests). He made some vague reassuring noises.
Just to be clear: This guy could be bullshitting me, his friend could be bullshitting him, heck his friend could be imaginary for all I know. At this point, I'm just curious...call it story research. Any answers appreciated]
