Last December 2022 I took the test. It came back negative. This August I started having problems. Went to the emergency room. They did a CT scan. A tumor was detected. On August 28 I had a tumor and part of my colon removed. Luckily it was stage two and had not spread. I would suggest doing a colonoscopy first, then later do the box. I was told it can't detect cancer when there is no blood in the stool. Take this seriously. I'm 68 and the first in my family to have colon cancer. My sister is having a colonoscopy Monday October 2 2023.
