This product is all about marketing and has nothing to do with "exact science." The box that showed up had enough information on it that let the whole UPS team what was shipped. My 12 y/o son was asking about "human specimen" written on the box. I received at least 3 texts, 3 emails and a phone call from these clowns. That's when I decided to check what it was all about. Terrible reviews, too many false positives, I mean no wonder it is RX only, clinics probably get a cut for pushing colonoscopies for people not comfortable with it due to all false positives these clowns are known for. They should be sued for malpractice. Total scam!
