See What Standard Blood Work Never Shows You
Conventional labs are designed to detect disease — not to find the root causes of how you feel. Our curated panel of advanced functional tests can help you uncover unnderlying stressors driving symptoms: hidden infections, toxin burden, hormonal imbalances, metabolic dysfunction, and more.
Why Functional Testing
Conventional Lab Work Doesn't Catch Everything
Standard blood panels use reference ranges based on the statistical average of a largely unhealthy population. You can fall within "normal" while your thyroid is underperforming, your gut is leaking, your hormones are imbalanced, and your toxic burden is quietly driving inflammation throughout your body. Functional lab testing uses tighter, optimal ranges — and tests for things conventional labs rarely do. The result is a completely different picture of your health.
Root Cause Identification
These tests are designed to find the underlying drivers of your symptoms.
Optimal vs. Normal Ranges
Results are interpreted at functional ranges that reflect optimal physiology, not just the absence of disease.
At-Home Convenience
Most tests use at-home collection kits — urine, dried blood spot, or stool — shipped directly to you with clear instructions.
Practitioner-Guided Review
Every test purchase includes a private 1-on-1 education session with Jacob and personalized wellness recommendations.
Featured Tests
Precision Tools for Root-Cause Discovery
Each test below has been selected because it reveals information that standard blood work cannot — and because it directly informs the root-cause protocols we use in practice.
FIT 176 + Gut Barrier Panel
Find out which foods are silently inflaming your body — and whether your gut wall has already been compromised.
Most food sensitivity tests only measure one type of antibody. The FIT 176 uses a patented dual-detection method that measures both IgG antibodies and immune complexes (C3d) against 176 foods, colorings, and additives — making it significantly more accurate at identifying delayed inflammatory reactions. The included Gut Barrier Panel adds four critical leaky gut markers: Zonulin, Occludin, LPS, and Candida. Together, these two panels reveal not just what you're reacting to, but whether your intestinal wall has already been breached.
What It Measures
- IgG1–4 + C3d reactivity to 176 foods, additives & colorings
- Zonulin & Occludin (intestinal tight junction integrity)
- LPS (lipopolysaccharide — bacterial endotoxin leakage)
- Candida antibodies (fungal overgrowth marker)
Organic Acids Test (OAT)
A metabolic snapshot of what's happening inside your cells — including hidden yeast, bacterial overgrowth, and mitochondrial dysfunction.
The Organic Acids Test is one of the most information-dense tests available in functional medicine. By analyzing 76 metabolic byproducts in a single urine sample, it reveals whether your mitochondria are producing energy efficiently, whether yeast or bacteria are overgrowing in your gut, how your body is metabolizing neurotransmitters, and whether you have critical nutritional deficiencies in B vitamins, CoQ10, or antioxidants. Particularly valuable for chronic fatigue, brain fog, and mood disorders.
What It Measures
- Yeast & fungal overgrowth (Candida, Aspergillus, and others)
- Bacterial dysbiosis markers
- Mitochondrial function & energy production pathways
- Neurotransmitter metabolites (dopamine, serotonin, norepinephrine)
- B vitamin, CoQ10, and antioxidant status
- Oxalate levels and oxidative stress markers
MycoTOX Profile
If you've ever lived or worked in a water-damaged building, this test may explain everything.
Mycotoxins — the toxic compounds produced by mold — are among the most potent biological toxins on earth. They are fat-soluble, cross the blood-brain barrier, and accumulate in fatty tissues. The MycoTOX Profile tests for 11 different mycotoxins in urine, including Ochratoxin A (linked to kidney damage and neurological dysfunction), Aflatoxin M1 (a known carcinogen), and Gliotoxin (an immune-suppressing toxin). Most conventional doctors never test for mycotoxins — yet mold illness is one of the most commonly missed root causes of chronic illness.
What It Measures
- Ochratoxin A (OTA) — kidney, brain, and immune toxin
- Aflatoxin M1 (AFM1) — IARC Group 1 carcinogen
- Gliotoxin — Aspergillus-derived immune suppressor
- Trichothecenes: Roridin E, Verrucarin A
- Zearalenone (ZEA) — estrogenic mycotoxin
- Mycophenolic Acid, Sterigmatocystin, Chaetoglobosin A, Citrinin
TruAge COMPLETE
Your birth certificate tells you how old you are. This test tells you how old your body actually is.
Biological age, measured through DNA methylation patterns across 900,000+ sites in your genome, reflects the cumulative impact of your lifestyle, toxin burden, stress, sleep, and nutrition on your cells. The TruAge COMPLETE measures not just your overall biological age, but your speed of aging (DunedinPACE), the biological age of 11 individual organ systems, and telomere length. For anyone doing a detox protocol, this provides the most objective measure of whether those changes are actually reversing biological aging at the cellular level.
What It Measures
- Overall biological age vs. chronological age
- DunedinPACE — speed of aging per calendar year
- Biological age of 11 organ systems (immune, metabolic, liver, kidney, heart, brain, and more)
- Telomere length
- Intrinsic vs. extrinsic biological age
- Immune cell composition and immune age
DUTCH Plus
The most complete hormone test available — measuring not just your hormone levels, but how your body is processing and clearing them.
Standard hormone blood tests measure total hormone levels — a single snapshot that misses most of what matters. The DUTCH Plus measures sex hormones and their metabolites in dried urine, revealing the full picture of how estrogen, progesterone, testosterone, and cortisol are being produced, converted, and eliminated. The DUTCH Plus uniquely adds the Cortisol Awakening Response (CAR) — the single most sensitive measure of HPA axis function and adrenal resilience available.
What It Measures
- Estrogen metabolites: E1, E2, E3 + 2-OH, 4-OH, 16-OH pathway breakdown
- Progesterone and testosterone metabolites
- DHEA-S and its metabolites
- Free and metabolized cortisol and cortisone
- Cortisol Awakening Response (CAR) — 5-point morning curve
- Melatonin (6-OHMS) and neurotransmitter metabolites
GI-MAP + Zonulin
The gold standard in stool testing — using DNA-based detection to identify exactly what is living in your gut.
The GI-MAP uses quantitative PCR technology — the same DNA-based detection method used in clinical infectious disease testing — to identify and quantify the microorganisms in your gut with precision that conventional stool culture cannot match. It detects H. pylori with virulence factors, pathogenic bacteria, parasites, fungi, and measures beneficial bacteria levels. The Zonulin add-on measures intestinal permeability directly — the leaky gut marker that explains how gut dysfunction becomes systemic inflammation and autoimmunity.
What It Measures
- H. pylori with virulence factors (CagA, VacA, OipA, DupA)
- Pathogenic bacteria: C. diff, E. coli O157, Salmonella, Shigella, Campylobacter
- Parasites: Cryptosporidium, Giardia, Entamoeba histolytica, and more
- Fungi and yeast (Candida species)
- Beneficial bacteria: Lactobacillus, Bifidobacterium, Akkermansia
- Immune markers: SIgA, calprotectin; Zonulin (leaky gut)
Comprehensive Blood Work — Men
A complete functional blood panel interpreted at optimal ranges — not just the disease thresholds your doctor uses.
Standard blood work is designed to detect disease — not to optimize health. This comprehensive panel is interpreted using functional ranges — tighter windows that reflect optimal physiology. It covers thyroid function (including the often-omitted Free T3 and Reverse T3), sex hormones, blood sugar and insulin resistance markers, inflammatory markers, iron status, key vitamins and minerals, and a full metabolic and cardiovascular assessment.
What It Measures
- CBC with differential, CMP
- Full thyroid panel: TSH, Free T3, Free T4, Reverse T3, TPO antibodies
- Sex hormones: total & free testosterone, SHBG, estradiol, LH, FSH
- Inflammatory markers: hs-CRP, homocysteine
- Metabolic/insulin: fasting glucose, fasting insulin, HbA1c
- Vitamin D, B12, folate, RBC magnesium; advanced lipid panel
Comprehensive Blood Work — Women
A complete functional blood panel for women — including the hormone and thyroid markers most doctors skip.
Women's health is uniquely complex — hormones fluctuate across the menstrual cycle, thyroid dysfunction is far more common in women than men, and the symptoms of hormonal imbalance and nutritional deficiency overlap significantly. This panel includes a complete thyroid assessment with antibodies (because Hashimoto's is the most common autoimmune condition in women and is routinely missed), sex hormones, AMH (ovarian reserve), and all foundational metabolic and inflammatory markers — interpreted at functional ranges.
What It Measures
- CBC with differential, CMP
- Full thyroid panel: TSH, Free T3, Free T4, Reverse T3, TPO & Tg antibodies
- Sex hormones: estradiol, progesterone, testosterone, SHBG, LH, FSH, prolactin
- AMH (anti-Müllerian hormone / ovarian reserve)
- Inflammatory markers: hs-CRP, homocysteine
- Vitamin D, B12, folate, RBC magnesium; iron panel
