Hi aaron,
I wasn't able to locate any specific details on this, but from what I could gather, 'askdocweb' mentions that, "Metronidazole can cause interference on EMIT assays that invalidates results."
I've been trying to figure out what exactly this means, but you can see where I referenced it from here:
askdocweb.com/falsepositives.html
NOTE: Just scroll down to 'Metronidazole', as the drug list is in alphabetical order.
Other than this, I haven't heard or read any statements involving this medication and false positives.
I hope this helps!
