Negative. Keep in mind that THC metabolite levels can fluctuate from day to day with the ebb and flow of your body. But if you're consistently testing clean, using the first urination of the day, you should feel very confident you'll pass. Just don't try to cheat by diluting for your home test. You want to test under a worst case scenario, if you can pass that, you should be good to go. Personally, I'd still send in the FirstCheck sample just for more reassurance.
