Once they receive the sample, I usually will get results to my inbox in 2-4 days. I like to use the UPS prepaid sample kits because they only take 2 days to deliver to them from my location. My job has a daily UPS pickup, so I just bring my sample to work, UPS picks up in the afternoon, and 2 days later, I get delivery notification. My most recent sample was picked up by UPS last Monday, delivered to OAI on Wed morning, and I got results by Monday morning (Memorial Day). Yeah, they sent my results on Memorial Day morning.
