Abstract
Disclosed is a method of diagnosing small intestinal bacterial overgrowth (SIBO), irritable bowel syndrome, fibromyalgia, chronic fatigue syndrome, depression, attention deficit/hyperactivity disorder (ADHD), or an autoimmune disease by sampling serum from a human subject having a suspected diagnosis of any of these conditions and analyzing the serum for the presence of ASCA, which corroborates the suspected diagnosis. A method of determining a predisposition for developing Crohn's, in a human subject who does not present a set of symptoms characteristic of the disease and who has small intestinal bacterial overgrowth, involves sampling serum from the subject and analyzing the serum for the presence of ASCA. The presence of ASCA in the serum indicates a predisposition for developing Crohn's disease. Also disclosed is a kit for diagnosing and treating small intestinal bacterial overgrowth, irritable bowel syndrome, fibromyalgia, chronic fatigue syndrome, depression, attention deficit/hyperactivity disorder, or an autoimmune disease, such as multiple sclerosis or systemic lupus erythematosus. The kit is useful to improve symptoms, including hyperalgesia related to SIBO and disorders …
