It is funny that you ask that because this came up a few weeks ago and we all thought it was a somewhat-humerous situation. Anyway, we weren't sure and used the materials for stool just for the heck of it. It came back positive. When we realized that we needed to send the emesis to the lab for a different test, that came back positive also. So, I guess it can work.

Do you used the same guaic materials to guaic emesis that you would to guaic stool?
