Still haven't heard anything, but it hasn't even been 24 hrs. I just took it yesterday at 2:00. I heard that if it's positive, the MRO will call you in 24 - 48 hrs to ask why, but that if it's negative dilute, they'll just send the results to the employer and they'll either call you to retest, move on to the next candidate, or just accept the results as negative. I'll post my results when I get them. Fingers crossed!
