Using Bodily Waste Smells To Test For Bowel Conditions

Wouldn't it be great if this means we don't have to go through scopes anymore? It makes sense because I heard that c-diff infections have a particular odor. I've heard of a nurse who dxd a patient with it because of the smell and when they got the official test results back, she was right. Not a very fun job though. Maybe they could train dogs like they do for sniffing out illegal drugs???
