Our Company

Commonwealth Diagnostics International (CDI), Inc.  is an international diagnostic service provider that specializes in bringing cutting-edge and innovative diagnostic products to patients and healthcare providers worldwide. Our services assist physicians and patients with the diagnosis of some of the common sources of digestive distress and functional gastrointestinal disorders.

Our hydrogen and methane breath testing services provide a fast, reliable and convenient diagnostic tool for identifying Small Intestinal Bacterial Overgrowth (SIBO), a leading cause of the symptoms associated with Irritable Bowel Syndrome (IBS). We also offer diagnostic tests for other common digestive disorders including: Lactose Intolerance, Fructose Intolerance, and Sucrose Intolerance. CDI’s affiliated laboratories provide an easy-to-use, take-home test kit that allows patients to administer the test and collect the specimen in the comfort of their own home.

Most recently, CDI introduced IBSchek™, a new blood test designed to help physicians quickly and reliably diagnose Irritable Bowel Syndrome. IBSchek is based on the scientific findings of Mark Pimentel, MD, Director of the Gastrointestinal Motility Department at Cedars Sinai Medical Center in Beverly Hills, California. Dr. Pimentel’s findings established that anti-vinculin and anti-CdtB are effective biomarkers for the diagnosis of diarrhea-prominent IBS. IBSchek utilizes a proprietary, ELISA-based blood test, and CDI provides results to the healthcare provider within 24 hours of receiving a patient specimen at CDI’s affiliated laboratories.
