Advanced Functional Testing

DUTCH, microbiome, mold & heavy metal testing

"Your labs are normal" usually means the wrong labs were run. These are the panels that explain the symptoms standard blood work misses — ordered by a physician, interpreted with you, and always tied to a treatment plan rather than a PDF.

DUTCH Test (Dried Urine Hormones)

DUTCH Complete · DUTCH Plus · Cycle Mapping

A dried urine test that measures your sex hormones and — critically — how you metabolize them, plus your daily cortisol curve. Blood tells us the level; DUTCH tells us the pathway.

What it shows

  • Estrogen metabolites (2-OH, 4-OH, 16-OH) and methylation of them
  • Progesterone metabolites, androgens including DHT
  • Free cortisol and cortisone rhythm across the day
  • DHEA-S, melatonin (6-OHMS), and organic-acid markers like B6, B12 and neurotransmitter clues
  • Cycle Mapping for women still cycling with unexplained luteal-phase symptoms

Who it's for

Estrogen-dominant symptoms, heavy or painful cycles, PMS or PMDD, stubborn perimenopause symptoms on hormone therapy, family history of hormone-sensitive cancer, unexplained fatigue with a suspect cortisol pattern, and anyone who wants their estrogen detox pathways checked before or during BHRT.

GI Microbiome / Stool Testing

GI-MAP · comprehensive stool analysis · SIBO breath test

PCR-based stool analysis that quantifies your bacteria, yeast, parasites and gut immune markers — instead of guessing from symptoms.

What it shows

  • Beneficial and opportunistic bacteria, dysbiosis patterns
  • Candida and other yeast overgrowth
  • Parasites, H. pylori (with virulence factors)
  • Leaky-gut and immune markers: zonulin, secretory IgA, calprotectin
  • Digestive function: elastase, steatocrit, beta-glucuronidase (which recycles estrogen)
  • SIBO breath testing when bloating and reflux point upstream

Who it's for

Bloating, reflux, constipation or loose stools, IBS labels, histamine and food reactions, rosacea and eczema, autoimmune disease, stalled weight loss, and estrogen recycling that keeps hormone therapy from settling.

Mold & Mycotoxin Testing

Urine mycotoxins · environmental screening · immune markers

Urine mycotoxin testing identifies specific mold toxins your body is carrying, paired with a look at your building and your immune response.

What it shows

  • Ochratoxin A, aflatoxins, trichothecenes, gliotoxin, zearalenone and more
  • Immune and inflammatory response (TGF-beta1, C4a, MSH where indicated)
  • Environmental correlation — ERMI/HERTSMI dust testing for your home or workplace
  • Detox capacity: glutathione status, liver markers, genetic detox variants

Who it's for

Symptoms that started after a water leak or moving, chronic sinus congestion, air-hunger, unexplained inflammation, MCAS-like reactivity, POTS, ice-pick headaches, tremor or brain fog that no hormone plan touches, and anyone whose whole household got sick together.

Heavy Metal & Toxic Element Testing

Urine (provoked & unprovoked) · blood · hair analysis

Testing for the metals that quietly disrupt thyroid function, mitochondria, fertility and cognition — with the right specimen for the right metal.

What it shows

  • Mercury, lead, arsenic, cadmium, aluminum, thallium, gadolinium
  • Essential mineral status alongside them — zinc, selenium, magnesium, copper
  • Blood levels for recent exposure vs urine for total body burden
  • Sources reviewed: dental amalgam, fish, well water, old paint, occupation, hobbies, cookware, imported cosmetics and supplements

Who it's for

Neuropathy, tremor, memory changes, treatment-resistant thyroid or autoimmune disease, infertility and recurrent miscarriage, chronic fatigue, unexplained anemia, and anyone with a known occupational or environmental exposure.

Good questions

Frequently asked.

Where can I get a DUTCH test near me in Northwest Arkansas?+

Dr. Tammy Tucker, MD orders and interprets DUTCH Complete, DUTCH Plus and Cycle Mapping at Healing Art Centers in Lowell, AR — about 10 minutes from Rogers, 15 from Bentonville and Springdale, and 25 from Fayetteville.

Do I need a doctor to order a DUTCH test?+

Yes — DUTCH is a provider-ordered test. More importantly, the value is in interpretation: metabolite ratios and cortisol curves change the treatment plan, and a PDF with no clinician attached rarely helps anyone.

Where can I get microbiome or GI-MAP stool testing near me?+

We order GI-MAP and comprehensive stool analysis for patients throughout Northwest Arkansas. Collection is done at home; results are reviewed in a follow-up visit with a written gut-repair protocol.

Where can I get tested for mold exposure or mycotoxins near me?+

We offer urine mycotoxin testing plus immune and inflammatory markers, and we can point you toward ERMI/HERTSMI dust testing for your home. Most patients in Rogers, Bentonville, Springdale, Fayetteville and Bella Vista drive in for the initial visit and collect the sample at home.

Where can I get heavy metal testing near me?+

Heavy metal and toxic element testing — urine, blood or hair depending on the metal and the question — is available at our Lowell, AR clinic. We always pair it with essential mineral status, because chelating without replacing minerals causes problems.

Does insurance cover this testing?+

Specialty functional panels are usually not covered by commercial insurance, though many are FSA/HSA eligible and some conventional labs can be run through your insurance. We give you pricing up front — no surprise bills. See why personalized care usually sits outside insurance.

How much does testing cost and how do I start?+

New patients begin with a consultation ($287), where we decide which panels are actually worth your money based on your history — we do not run everything on everyone. Panel pricing is quoted before anything is ordered. Call or text 479-715-3928.

How long do results take?+

Most specialty panels return in 1–3 weeks after the lab receives your sample. We schedule your review visit when we send the kit so there is no waiting around afterward.
