    Faecal occult blood test (FOBT) screening - failed one sample

    Hi My doctor called me the other day relating to my routine Government FOBT screening informing me that one of the samples came back positive for blood. We discussed the option of doing a second test or going for a colonoscopy, and the doctor suggested the latter, as doing a second test may still cast doubt if it came back negative. The day of the sample that came back positive, I was constipated and did not pass much movement. I think that I have had a small haemorrhoid which may be the culprit and I mentioned this to the GP. However, he did not examine for this. Rather than go in feet first, I was hoping that I could get some guidance as to whether I should consult with the specialist prior to going for the colonoscopy, as I have already booked it in, or should I go for a second test? Your thoughts would be greatly appreciated.
