While the final outcome of my pre-employment screen is still pending, I'm freaking out from an invalid result that's been sent for more testing. It's been almost a month, I'm in N.C. so that might influence results. Followed directions perfectly, temp was great, no hiccups. Company I bought from was dumbfounded. After more and more research, it appears the Canadian version is the best one to use. But I doubt I'll ever use synthetic again. Frozen or freeze-dried/powdered options are best next to abstinence, especially for unsupervised screenings. From the research I've come across, it's a 50/50 chance I could get a retest, probably supervised. Any words of reassurance appreciated. Anyone else have something like this
