Who CDI Serve | Commonwealth Diagnostics International


As the healthcare paradigm continues to shift in the US, gastroenterology as a specialty is facing many of the same challenges and obstacles that the rest of the medical community is coming to grips with. As the delivery and reimbursement of health care become more value-based, invasive and expensive methods of diagnosis like colonoscopies and endoscopies are receiving lower reimbursements and increasingly substituted or supplemented with less costly and less invasive specialty diagnostics. At the same time, patient needs and expectations for comprehensive care, information and monitoring, and symptom management are increasing. One of the leading challenges for gastroenterologists today is setting themselves apart by creating value and delivering quality services to their patients in a timely and cost-efficient manner. We support your ability to provide complete, accurate, and thorough care for patients with gastrointestinal conditions, which distinguishes gastroenterologists from other physicians that provide some similar services.

Primary Care Physicians

As a primary care physician (PCP), you are the first line of medical defense for millions of patients entering the healthcare system with gastrointestinal ailments and symptoms of chronic stomach conditions. Your patients count on you to treat, manage, recommend steps to help them improve their health, and refer them to qualified specialists when appropriate. We appreciate the value of patient-centered medicine and a PCP’s role in helping patients get an early diagnosis leading to expedited therapy and better clinical outcomes. We are committed to empowering you with the most reliable, simplest, and highest quality diagnostic tools to help you identify some of the most common gastrointestinal disorders that patients may walk into your practice with.

Integrative Physicians, Naturopaths & Dietitians

Integrative physicians, naturopathic doctors (NDs), and registered dietitians (RDs) receive extensive training in understanding the complexities and interrelations of digestive wellness and overall body health. The holistic approach to health, wellness, and nutrition strongly emphasize disease prevention. A central tenant of this approach is that good health starts with good digestion. Impaired nutrient absorption and energy creation can lead to a host of other issues down the road for patients. Our at-home diagnostic tests can help identify functional GI disorders including dietary sensitivities and help steer you and your patient’s approach to dietary modification, homeopathic remedies, nutritional supplementation, immune support, high-quality probiotics, and additional testing.

Clinical Researchers

One of the driving forces at CDI is our company-wide desire to contribute to ongoing research and development activities relating to the treatment, diagnosis, and prevention of functional GI disorders. Our laboratory management team has had extensive experience in establishing and developing analytical methods and protocols specific to clinical trials to accommodate both small and large-scale studies while maintaining all regulatory requirements. Using our state-of-the-art laboratory and expertise in clinical trial management, our experienced biochemical and analytical scientists have supported clinical trials for international sponsors, contract research organizations, and principal investigators to reach successful outcomes of their trials and research studies.

The type of diagnostic approach you take for your patients depends on each individual patient case, and we know that the accuracy and speed with which data is delivered to you to guide that approach is critical to your ability to be effective. CDI has the tools to give every provider the important clinical data that both you and your patients are looking for, and we are committed to delivering our services in the most convenient, customer-centric, and effective manner available.
