I had a false positive cologuard. My first, at 55, was negative. The second, at 58, was positive. That result I received via email. There was some small print that basically said 4% of positive cologuard results = CRC. The rest (51%) are either polyps (benign or pre-cancerous) or "no colorectal neoplasia" (45%). My colonoscopy found nothing at all. From the positive result to the procedure was exactly one month.
