Doctor's Data

Since 1972, Doctor's Data, Inc. (DDI) has been providing innovative specialty testing to healthcare practitioners worldwide from their advanced clinical laboratory. As specialists and pioneers in essential and toxic elemental testing, they offer a wide range of functional tests to support decision-making and enhance patient outcomes. Their mission is to research, develop, and offer innovative tests that help healthcare practitioners identify health risks and improve outcomes for patients with chronic conditions. They also focus on educating and supporting healthcare professionals, aiming to improve lives through science. DDI assists in assessing and treating heavy metal burden, nutritional deficiencies, gastrointestinal function, hormone status, cardiovascular risk, liver and metabolic abnormalities, and more.

Research Commitment

DDI supports cutting-edge research in collaboration with prominent global institutions. Their research focuses on raising awareness of the role of elements in clinical biochemistry and medicine. They have participated in studies on:

  • Intellectual and neurological development and behaviour in children
  • The adverse effects of toxic waste and heavy industrialisation on hypertension, cardiovascular disease and other conditions
  • The biochemical connection between aberrant behaviour and violence in juveniles and adults
  • Zinc deficiency and suppression of growth in humans

They have partnered with Argonne National Laboratory, Brookhaven National Laboratory, Johns Hopkins Hospital, the European Commission Joint Research Centre, the United States Navy, the California Criminal Justice System, the Oklahoma Department of Health and Human Services, and the universities of California, Florida, Illinois, and Texas, among others.

Clinical Laboratory and Technologies

Doctor's Data has created a modern facility equipped with the most advanced instrumentation to support their scientific team. The laboratory is designed to ensure optimal cleanliness, contamination control and streamlined specimen flow. The team uses advanced instruments such as dynamic reaction cell inductively coupled plasma mass spectrometry (DRC-ICP/MS) for elemental analysis, DNA amplification assays, and automated identification and antimicrobial sensitivity instruments for detecting bacterial resistance mechanisms and phenotypes in their clinical microbiology department.

Pioneering Technologies

Committed to accurate, sensitive, and cost-effective analysis, DDI employs the best available techniques. They were among the first clinical reference laboratories to use ICP-MS and high-resolution ICP-MS and are leaders in GC/MS, UHPLC, LC/MS QQQ, and the latest automated microbiology systems.

As a doctor dedicated to providing the highest level of care, I rely on Regenerus for my testing needs. Their GI360 stool test is simply unrivalled, and the Dutch test has been a game-changers for treating my patients. The Regenerus platform makes ordering tests and accessing results seemless, and their customer service is top-notch, always ready to support with any queries. I also appreciate their ongoing educational resources, which keep me informed about the latest advancements. Regenerus sets the standard in functional medicine testing.

Sara Bayley

When I have a client concerned about their cholesterol levels I always suggest the Doctors Data Cardiometabolic test. It allows us to see what's happening at a much deeper level by properly assessing the risk of atherosclerosis and whether there is any developing insulin resistance playing a part. This is one of the most empowering tests that my clients can do and allows them to take exactly the right action for longterm cardiovascular health.

Ellen McCallum

In cases of suspected digestive issues it is a first port of call but also I will often run it when clients present with mixtures of symptoms with no obvious cause, frequently when there are energy, inflammation or cognitive issues. It enables me to see the health of the microbiome as well as microbiology and parasitology. The section on Stool chemistry often yields very helpful information on absorption, immunology, metabolism and localised inflammation. When there is anything urgent to look at the lab will issue an interim report.

Cynthia De Maria

Regenerus' portal is one of the easiest portals to order and retrieve results for my clients, There is a broad selection of tests including the GI360 and Methylation which are common tests I use at the clinic, The support team are very helpful, And I always look forward to any practitioner training they may have.

Juliana Bernardes

With the GI360 stool test, I get clear insights into markers like gut flora balance, digestive function, inflammation levels and more. In a time when gut issues are so common among clients, this test takes the guesswork out of identifying root-cause problems like, for example, dysbiosis or reduced digestive capacity. It helps me create precise, effective treatment plans and ultimately leads to better client results
