Precision Analytical is a CLIA certified laboratory based in Oregon, USA. It is run by a team of dedicated scientists with over 50 years combined experience in performing laboratory testing and the development of innovative testing methodology. After extensive experience working within numerous well-known hormone testing laboratories, Precision Analytical was established by Mark Newman to address the need for better clinical accuracy, convenience and relevance compared with existing conventional hormone testing methods. Subsequently developing one of the most advanced and comprehensive models for testing a patient’s steroid and adrenal hormones.

DUTCH (Dried Urine Testing for Comprehensive Hormones) was the result of this extraordinary endeavour.

In the process of developing this unique testing process, Precision Analytical has harnessed almost all primary hormone assessment methods available (including immunoassay/ELISA, colorimetric, GC-MS, LC-MS, LC-MS/MS, GC-MS/MS), to arrive at a process that uses each where they are most appropriate and accurate for the specific hormones in question, and for the purposes of clinical assessment (including where supplementation occurs). As a result practitioners can be confident in offering their patients the most accurate and comprehensive hormone testing available.

KBMO is one of the few breakthrough labs to measure Complement as part of their Food Inflammation Testing, acquiring a more complete look at the patient’s reaction level compared to IgG testing alone. As a CLIA certified lab, KBMO track reproducibility to ensure reliable results, every time. Under founder Dr. Dorval’s leadership, KBMO’s approach to quality, accuracy and reproducibility has been based on their roots in the HIV testing arena, where there is no room for error.

Located in Byron Bay, NSW and founded by Dr. Nirala Jacobi, BHSc, ND (USA), who graduated from Bastyr University in 1998 with a doctorate in naturopathic medicine. Dr Jacobi is considered one of Australia’s leading experts in the natural treatment of small intestine bacterial overgrowth (SIBO), a common cause of IBS.

Labrix was founded by clinicians Jay H. Mead, MD, FASCP and Erin T. Lommen, ND with the goal of raising the bar on quality hormone testing. With Dr. Mead’s 25 years in laboratory medicine, plus the doctors combined 40 plus years in clinical practice, Labrix founders were well positioned to achieve their goal. In a few short years, Labrix has become recognised for setting a new standard for saliva testing in accuracy, reliability and turnaround times.

Dunwoody Labs is A CLIA licenced laboratory located in Dunwoody, Georgia, USA.

The birth of Dunwoody Labs came out of a clinical need for certain testing profiles that were not currently on the market. Founded by Dr. Cheryl Burdette, ND, a clinical healthcare practitioner who noticed that many tests exist in academia or research settings, but may lag in commercial availability to clinicians.

As much as modern healthcare is directed at defining a disease process and blocking it, Dunwoody saw the need to more effectively evaluate systems in the body, and provide these insights to practitioners. The analytes that Dunwoody bring to the market have been extensively studied in 1000s of published papers – to put well-researched lab methodologies in the hands of clinical healthcare practitioners.
