Yep, exactly what I don't want to happen.

I had the impression that medical privacy ethics and laws were supposed to forbid that transfer of information. I thought the lab was only to tell your HR department about an actual failure of the screen, and that false positives would be suppressed.

But, obviously, people don't always stick to ethics and laws.

Any idea why they would look for Prozac? Usually they're only after commonly abused and illegal drugs. I'm not a lawyer, but an employer digging into your body to determine that you're using Prozac doesn't even sound legal (disability laws and whatnot).
