If MDMA is used, and ~7 days later drug test hits for amphs, what will GC/MS show?

Title. A buddy of mine took a really clean, well reputed roll a few days back. His drug test is 7 days following. He's aware that MDMA can be detected in urine up to 3 days in most cases, but that a standard 8-panel may hit positive for amphetamines or methamphetamines up to 5 days after MDMA usage.

Considering he is a heavy drinker and estimates that about ~48 hours of the 7 day span was spent primarily metabolizing alcohol rather than other substances, he is concerned his test will indeed test positive for amp/methamp.

So the question is, if it were to, and they were to send it off for GC/MS confirmation, would they just consider it a false positive with no distinct results, or would there be any way for them to get back in the results that it was caused by MDMA? Or is there a third option here?

Cheers!

I'm sorry but bluelight doesn't allow drug testing questions as you can read in the rules you agreed to when you signed up. It's next to impossible to accurately answer these and doing so is of questionable legality, which may bring negative law enforcement attention to this forum. Closing this
