The diagnosis of EB (Epidermolysis Bullosa) is based on a combination of factors. Option a, endoscopy and biopsies of the distal esophagus, may be used to evaluate the involvement of the esophagus in certain types of EB. Option b, blood tests and imaging exams, can help identify specific markers or abnormalities associated with EB. Option c, physical examination and medical history, are important for assessing the clinical manifestations and identifying characteristic signs and symptoms of EB. It is important to note that the diagnosis of EB is usually made by a dermatologist or a specialist in genetic disorders.
