Functional Lab Testing

Most standard lab panels are designed to detect disease — not optimize health. My functional panels go deeper, and every result is reviewed by me, personally.

These panels are available to anyone, anywhere — no office visit required. If you're a local, established patient, most testing is run through your insurance during a visit instead — see Getting Started on the homepage.

What makes this different

Real biomarkers, reviewed by a real physician.

Standard lab work is built to catch disease once it's already present — using reference ranges wide enough to flag only the most serious problems. My functional panels measure a broader set of biomarkers and interpret them using optimal ranges, so you can see patterns years before they'd show up on a conventional panel.

Every panel here is ordered, reviewed, and interpreted by me — personally. You receive a plain-language explanation of what your results mean — real insight, not just a number on a page with no context.

"Unlike large testing programs where you don't know who's reviewing your results, every panel ordered through my practice is personally reviewed by me — Dr. Barbie — with 15 years of functional medicine expertise behind every interpretation."

Why these panels

Built from what I actually see in practice.

Each panel here reflects markers I've found meaningfully change how a patient understands their own health — not a generic checklist. Some are broad starting points, others are narrow and targeted for a specific concern. Wherever you start, there's a natural next step once you see your results, and I'll point you toward it.
