Define GI bleeding: Melena, by definition, is passage of dark stools stained with denatured blood but all dark stool is not melena. Your doctor, or even an over-the-counter test that you can purchase, can check to see if your dark or maroon-colored stool contains blood. False positive results can occur based on diet ; stool additives. Taking Lovenox (enoxaparin) raises the stakes that you may indeed be slowly bleeding from gut.
