Are negative reports allowed?

In the spirit of adventure and enquiry I have completeda liver flush, and I had intended to send the green blobs to the lab. I have changed my mind because I would never live it down. When I put the blobs in the Normal saline in a pathology jar the saline clouded and it was obvious that these were not gallstones. I crushed one and the structure was not like a gallstone would be. Food was mixed into the blobs.
