Not if melena: Melena is dark stools stained with denatured blood, but all dark stool is not melena. False positive hemoccult results can occur based on diet & stool additives. However, colonoscopy can result in bleeding due to biopsies, scope abrasion/trauma, post-polypectomy oozing, etc. By all means, call your colonoscopist now & alert them to your concern--they know your risks & will be eager to assist you..
