I was mixing fake stool for my students to do an occult blood test out of chocolate pudding and applesauce. I was surprised it came up positive. Multiple times. I'm trying to place what would cause a positive. Any ideas? For some reason I'm blanking rationale of what would cause a positive.

At my hospital training, they made fake poop out of chocolate for both the negatives and the positives. Just added some (real) blood for the positive samples.
