3. Getting a Diagnosis
First, it needs to be determined if there's blood in the stool before investigating the cause. A medical professional should provide a diagnosis, which is normally done by analyzing a fecal sample provided by the affected individual. Rectal exams are another diagnostic tool used to determine melena.
When the diagnosis is confirmed, a physician may order a few tests to pinpoint the location of the bleeding. Tests may include an EGD, colonoscopy and X-rays.2Tresca, Amber J. ‘What Are the Causes of Black Stool?’ Verywell Health, www.verywellhealth.com/causes-of-black-stool-1941711.
