Functional Lab Testing

For Hormones, Gut Health, & Root Cause Healing.

Functional Labs help us to get a closer look at what is happening inside the body, to best identify and address the root causes of your symptoms

Personalized, Integrative Testing to Understand What Your Body Is Really Telling You

If you’ve ever been told “your labs are normal” but you still don’t feel like yourself—you’re not alone.

At Whole Lifecycle Nutrition, we believe that lab work should validate your experience, not dismiss it. That’s why we use functional lab testing to go deeper and uncover what’s really going on beneath the surface. Whether you’re struggling with hormonal imbalances, chronic fatigue, digestive issues, inflammation, or mood swings, functional labs give us the insight to create a personalized, whole-body healing plan—based on data, not guesswork.

Why Functional Testing?

Conventional lab tests often focus on disease diagnosis and are designed to detect problems once they’re severe enough to fall outside a “normal” range. But what’s considered “normal” isn’t always optimal—especially when it comes to female hormone health, thyroid function, stress response, and gut integrity.

A Functional, Female-Centered Approach

As an integrative and functional nutrition practice, we specialize in helping women understand their bodies at a deeper level. Whether you’re navigating PCOS, PMS, perimenopause, postpartum depletion, or mystery symptoms no one else has been able to explain—functional lab testing gives us a roadmap to guide your healing.

We don’t guess. We test, interpret, and support the whole person—mind, body, and gut.

Functional Medicine Tests help us:

✓ Detect subtle imbalances in estrogen, progesterone, cortisol, thyroid hormones, and other key pathways

✓ Assess gut microbiome diversity, leaky gut, pathogens (like parasites or H. pylori), and inflammation

✓ Identify nutrient deficiencies impacting energy, mood, metabolism, and immune function

✓ Understand how your body is processing hormones, detoxing, and managing stress

We use cutting-edge tests like:

✓ DUTCH Complete™ for a full picture of hormone patterns and adrenal health

✓ GI-MAP or Comprehensive Stool Analysis for gut microbiome, digestion, and immune markers

✓ Organic Acids Testing (OAT) for mitochondrial function, neurotransmitter metabolites, and detox

✓ Nutrigenetics Testing to get the “why” behind your personal health and create a “genes first” approach to your health plan.

✓ Micronutrient Panels, food sensitivity testing, and more

I did the 3×4 genetic testing and it was so cool and interesting! I learned a lot about myself, but I also feel like it reinforced a lot of what I knew. It feels good to have real answers about my health and not just a guess. Rachel put together a list of custom supplement and food recommendations for me based on my results. I highly recommend the test.

DUTCH Hormone Testing

The DUTCH Complete is a noninvasive test that uses dried urine to provide a comprehensive look into how a person’s sex and adrenal hormones are functioning. The test also looks at organic acids, metabolites in the urine which provide insight into nutritional deficiencies, oxidative stress, gut dysbiosis, melatonin, neurotransmitters, and inflammation.

DUTCH Cycle Mapping

The DUTCH Cycle Mapping test combines the DUTCH Complete with a map of the progesterone and estrogen patterns throughout the entire menstrual cycle. This is the best test to take a deeper dive into fertility, PMS, irregular cycles, PCOS, and other hormone imbalances. This test is not indicated for postmenopausal women or women taking hormonal birth control.

GI Map

The GI Map stool testing uses quantitative polymerase chain reaction technology to detect parasites, bacteria, and fungi by targeting the specific DNA of gut microbiome organisms. This test provides an in-depth look at the richness and diversity of the gut microbiome, which is associated with dozens of health conditions and overall wellness. Stool tests are not only for people experiencing GI symptoms. Identifying gut dysbiosis and treating it may play a key role in preventing chronic disease. The GI Map not only assesses the condition of the gut microbiome, but digestion and absorption of nutrients, and inflammation.

SIBO Testing

Small intestinal bacterial overgrowth breath test kits by Commonwealth Diagnostics and Genova Diagnostics can diagnose SIBO by measuring fermented gasses methane, hydrogen, and carbon dioxide. Lactulose or glucose is used as a substrate. The test takes place over two to three hours and involves blowing gas into a collection tube. SIBO may cause unwanted weight loss, malnutrition, and uncomfortable symptoms like diarrhea and painful bloating after meals. These noninvasive tests can help to identify or rule out SIBO to get relief faster.

Nutrition Panels

There are a variety of excellent options to choose from. These tests help to assess the functional need for antioxidants, B-vitamins, minerals, digestive support, fatty acids, and amino acids. The Metabolomix+ test analyzes key nutritional biomarkers, including organic acids, amino acids, and oxidative stress markers. This is a go-to test for clients experiencing chronic stress, fatigue, mood disorders, or inflammation. Micronutrients testing can evaluate the extracellular and intracellular levels of vitamins and minerals. Organic acids testing provides a metabolic snapshot of a patient’s overall health.

Metals, Molds, and Toxins

There are opportunities for most people to be exposed to environmental toxins and heavy metals every day. Many people are exposed through their occupation. They may be inhaled, or absorbed through the skin. Too much exposure can lead to toxicity and damage to our bodies. Testing may use blood, urine, fingernails, or hair. The best treatment is usually to identify and remove the source of exposure.

Fatty Acids Testing

There are several tests that measure the Omega-3 Index, the Trans Fat Index, the Omega-6/Omega-3 ratio, and the AA/EPA ratio. Many studies have shown that people with higher (vs. lower) omega-3 index levels are at a decreased risk for disease. Testing can identify omega-3 status to help make precise nutrition recommendations.
