The Best Functional Lab Tests for Endometriosis Root Causes
If you’ve been diagnosed with endometriosis—or strongly suspect it—you’ve probably been told your options are limited: birth control, painkillers, maybe surgery. But those don’t address the root causes, and many women still struggle with painful symptoms or fertility challenges after trying them.
Endometriosis isn’t just a hormone issue—it’s a complex inflammatory, immune, and estrogen-sensitive condition that can benefit from a much deeper and more individualized approach.
In this post, we’ll go over the best functional lab tests to understand the root causes of endo and how they can guide your strategy for pain relief, hormone balance, and fertility.
Struggling with endo?
🌿 Why Functional Testing Matters for Endometriosis
Endometriosis affects much more than your reproductive organs. It’s a whole-body condition that can be impacted by:
Hormone imbalances (especially progesterone resistance and estrogen overload)
Gut health and microbiome imbalances
Inflammation and immune dysfunction
Oxidative stress and poor detox capacity
Mineral imbalances and adrenal stress
Functional lab tests go beyond standard hormone panels and can uncover what’s actually driving your symptoms, whether that’s painful periods, fatigue, bloating, or trouble conceiving.
🧪 1. DUTCH Test (Comprehensive Hormone Test)
The DUTCH test is a dried urine test that looks at:
Estrogen levels + how your body metabolizes and clears estrogen
Progesterone production and patterns
Cortisol levels + stress response (often a key factor in endo)
Androgens (DHEA, testosterone) if acne or mood issues are present
Why it’s helpful for endometriosis:
Many people with endo have normal estrogen on bloodwork but poor metabolism through the 4-OH pathway, which is inflammatory
It reveals progesterone resistance, even if serum levels look “normal”
It shows how stress may be suppressing ovulation or increasing inflammation
🔎 Bonus: If you also deal with PMS, irregular cycles, or low libido, the DUTCH test is a great starting point.
🧪 2. GI MAP Test (Comprehensive Gut Health Panel)
The GI MAP is a stool test that looks at:
Gut pathogens (like H. pylori, candida, parasites)
Inflammation markers (like calprotectin and secretory IgA)
Leaky gut indicators
Beta-glucuronidase, an enzyme that recirculates estrogen in the body
Why it’s helpful for endometriosis:
Gut health directly affects estrogen detox and immune balance
Chronic inflammation in the gut can worsen endo symptoms
High beta-glucuronidase = estrogen gets reabsorbed instead of cleared
A compromised gut barrier can trigger more systemic inflammation
🔎 This test is essential if you have both endo + digestive symptoms (bloating, constipation, food sensitivities, nausea).

🧪 3. HTMA (Hair Tissue Mineral Analysis)
HTMA shows your long-term mineral status and stress patterns, including:
Calcium, magnesium, sodium, potassium (key hormone co-factors)
Copper and zinc balance
Heavy metal burden (like mercury or aluminum)
Adrenal patterns (burnout, compensation, etc.)
Why it’s helpful for endometriosis:
Chronic stress depletes magnesium, potassium, and zinc, which are essential for progesterone production and inflammation regulation
Copper imbalances may play a role in estrogen sensitivity
Heavy metals and mineral imbalances can worsen oxidative stress
🔎 HTMA is great for those feeling burnt out, sensitive to supplements, or overwhelmed by symptoms that don't make sense on standard labs.
🧪 4. Bloodwork (Foundational Testing)
While functional tests give deep insight, it’s still important to include comprehensive blood labs for a full picture. These can include:
Vitamin D – low levels increase inflammation and are common in endo
TSH, Free T3, Free T4 – thyroid health impacts cycle regularity and hormone clearance
Ferritin and Iron panel – heavy periods can deplete iron, affecting energy and fertility
CRP or hsCRP – to assess systemic inflammation
Fasting insulin + A1C – blood sugar issues can worsen hormone imbalances and inflammation
🧩 How to Choose the Right Tests for You
Not everyone needs all four tests to start. Here’s a general guide:
Trying to conceive or optimize your cycle? → DUTCH + bloodwork
Pain + bloating + estrogen issues? → GI MAP + DUTCH
Stress, burnout, or supplement sensitivity? → HTMA + DUTCH
Want the full root cause picture? → A bundle of DUTCH, GI MAP, and HTMA offers deep insight into hormone, gut, and mineral balance
Final Thoughts
Endometriosis isn’t just a reproductive issue—it’s a whole-body condition that deserves a whole-body strategy. Functional lab testing helps you move beyond symptom management and finally uncover what your body needs to reduce inflammation, support hormones, and improve your fertility outcomes.
You don’t have to guess, push through, or wait until things get worse. There’s a way to move forward that’s grounded in your body’s data and supported by root cause healing.
