Try not to worry too much, if you usually only have a bm once a week with dulcolax, it's highly unlikely that everything in you made it out with this BM. I had a small BM during my sitzmark test and all of the markers were still in me. And you can always tell your doctor your concerns about eating a bad meal and getting sick. If you feel your results are not accurate you can ask to repeat the test. And don't worry about what the doctors will think...they know that most people wouldn't lie about something like constipation.
So try not to worry too much!
