Hello

If they did not send the sample for confirmatory testing [GC/MS] then they can not say it was positive.

If they tested specifically for cocaine and its metabolite, or if they did confirmatory testing, then the test is not inaccurate. At this point, the only explanation would be that samples were mixed up. Lab error.
