Excellence You Can Trust
Beyond Standard Labs
Why Root Cause Testing?
Standard blood panels often tell you what's wrong without explaining why. Our specialized functional tests dig deeper—evaluating hormones, gut health, toxin exposure, food sensitivities, and metabolic function to reveal the underlying factors influencing how you feel.
Each test is selected based on your symptoms, history, and goals. The results guide personalized protocols designed specifically for your unique biochemistry.

Questions & Answers
Testing FAQs
During your initial consultation, we'll review your symptoms, health history, and goals to recommend the most relevant tests. We only suggest testing that will provide actionable insights—not a one-size-fits-all panel.
Coverage varies by insurance plan and specific test. Some tests may be partially covered, while others are typically out-of-pocket. We'll provide cost estimates upfront and can help you understand your options before testing.
Turnaround times vary by test—typically 1-3 weeks depending on the laboratory and complexity. We'll give you an estimated timeline when ordering and schedule your results review appointment in advance.
Many of our tests—including urine, stool, and saliva collections—can be completed at home with kits we provide. Some blood tests require a visit to our office or a local lab. We'll provide clear instructions for each test.
We'll schedule a comprehensive results review where we explain your findings in plain language and present a personalized protocol based on your unique results. This includes dietary recommendations, supplements, lifestyle changes, and any additional interventions needed.
Standard labs typically check if you're within "normal" ranges—which are based on population averages, not optimal health. Our functional tests look deeper at hormone metabolism, gut microbiome, toxin exposure, and cellular function to identify why you feel the way you do.
