How to Interpret a DUTCH Complete Hormone Panel: A Physician's Guide

At a Glance

The DUTCH Complete — Dried Urine Test for Comprehensive Hormones, developed by Precision Analytical — is the most information-dense single hormone panel available in functional medicine practice. A standard morning serum estradiol and testosterone tells you what was circulating at 8 a.m. on one particular day. The DUTCH tells you how the body makes those hormones, how efficiently it clears them, which metabolic pathways are active, whether adrenal function is sustained through the day, and whether key cofactors are adequate for methylation of potentially genotoxic estrogen metabolites.

This article walks through each section of the DUTCH Complete systematically, with the pattern recognition I use clinically at St. George Hospital. It is not a substitute for the Precision Analytical educational portal or for physician supervision — but it gives patients and referring clinicians the vocabulary to hold a meaningful conversation about what the numbers mean.

Section 1: Sex Hormones — Estrogens

The DUTCH reports three estrogens: estradiol (E2), estrone (E1), and estriol (E3), expressed as creatinine-adjusted daily output in nanograms.

Estradiol is the dominant premenopausal estrogen and the most potent. Low E2 with symptoms (hot flashes, vaginal dryness, mood instability, poor sleep) supports hormone therapy; high E2 in a peri-menopausal woman with heavy periods points toward relative progesterone deficiency. Neither is visible from a random serum draw.

Estrone rises relative to E2 after menopause because peripheral fat tissue converts adrenal androgens to E1. An E1/E2 ratio above 2.5 in a symptomatic post-menopausal woman suggests inadequate E2 supplementation is being partially compensated by adipose conversion — clinically relevant when dosing transdermal estradiol.

Estriol is often the forgotten estrogen. It is produced primarily in the placenta during pregnancy and otherwise reflects conversion from E2 in the liver. Low E3 relative to E1 is a minor finding on the DUTCH but matters in the context of vaginal microbiome and mucosal protection.

Estrogen Metabolite Pathways — The Most Clinically Critical DUTCH Section

The liver hydroxylates estrogens into three competing metabolites, and which pathway dominates has material consequences for long-term cancer risk:

• 2-OH-estrone (2-OHE1): The protective pathway. 2-hydroxy estrogens bind estrogen receptors weakly and are readily methylated and cleared. High 2-OHE1 relative to 16-OHE1 is the desired pattern.
• 4-OH-estrone (4-OHE1): The genotoxic pathway. 4-hydroxy estrogens can be oxidized to quinones that form DNA adducts. Elevated 4-OHE1 is associated with increased breast cancer risk in epidemiological studies and is the primary target of DIM (diindolylmethane) supplementation.
• 16-OH-estrone (16-OHE1): Proliferative but not directly genotoxic. High 16-OHE1 is associated with heavier periods and greater estrogenic stimulation of breast tissue; some data link it to endometrial proliferation.

The 2:16 ratio (2-OHE1 divided by 16-OHE1) should ideally be above 2.0. Values below 1.0 suggest meaningful estrogen pathway imbalance. Cruciform vegetables (broccoli, cauliflower, Brussels sprouts) and I3C/DIM supplementation shift hydroxylation toward the 2-OH pathway.

Methylation of 2-OHE1 to 2-MeOE1 is the step most commonly impaired in patients with MTHFR variants or B12/folate deficiency. The DUTCH reports the 2-OHE1-to-2-MeOE1 ratio; a low ratio means the protective 2-OH metabolite is not being efficiently methylated and cleared. This is one reason methylation support is central to estrogen detoxification protocols.

4-OHE1 methylation to 4-MeOE1 follows the same logic. When methylation is impaired, 4-OHE1 accumulates and has more time to oxidize to quinones. The DUTCH reports both the raw 4-OHE1 level and its methylation efficiency, which together determine actual genotoxic exposure more accurately than either number alone.

Section 2: Androgens — Testosterone and DHEA

The DUTCH reports testosterone, DHEA-S, and their downstream metabolites (androsterone and etiocholanolone) plus 5α-androstanediol and 5β-androstanediol, which reflect 5α-reductase and 5β-reductase activity respectively.

Why metabolites matter: A man with normal serum testosterone but elevated 5α-androstanediol has high 5α-reductase activity — meaning more testosterone is converting to DHT, which drives prostate proliferation and hair loss. A woman with high androsterone and normal DHEA may have elevated adrenal androgen output not fully captured in serum DHEA-S. These distinctions shape treatment.

DHEA and DHEA-S reflect adrenal androgen production. Low values are common with HPA axis dysfunction, chronic stress, aging, and post-COVID syndromes. High values in a woman with irregular cycles and acne point toward adrenal androgen excess — potentially PCOS or late-onset congenital adrenal hyperplasia — even when serum DHEA-S is borderline.

Clinical pattern: Low total androgens with normal serum testosterone. This occurs when serum testosterone is measured in the morning at peak (which is normal) but 24-hour urine output is low, suggesting insufficient sustaining production. These patients often report afternoon energy crashes and reduced exercise tolerance.

Section 3: Progesterone Metabolites

Serum progesterone is only useful when drawn on day 21 of a regular cycle — a condition rarely met in perimenopause. The DUTCH reports pregnanetriol and pregnanediol, the two major progesterone metabolites, which reflect cumulative daily progesterone production rather than a single draw.

Low pregnanetriol and pregnanediol in a woman with estrogen dominance symptoms (breast tenderness, bloating, mood swings in the luteal phase, sleep disruption) confirms relative progesterone deficiency. The ratio of estrogen to progesterone metabolites guides dosing of bioidentical progesterone more precisely than serum alone.

Post-menopausal women on progesterone therapy can use DUTCH to assess whether transdermal or oral progesterone is achieving adequate tissue levels — serum measurements after oral micronized progesterone are confounded by rapid hepatic first-pass metabolism.

Section 4: Cortisol and the HPA Axis

This is where the DUTCH is most often misread. The test reports four distinct cortisol measures, each answering a different clinical question:

4a. Free Cortisol (Four Urine Collection Points)

Free cortisol reflects active, unbound cortisol at each collection time. A healthy pattern shows an elevated morning value (the cortisol awakening response) that declines through the day.

Pattern: High free cortisol throughout → active HPA activation; may reflect ongoing stress, subclinical hypercortisolism, or poor stress resilience.

Pattern: Low free cortisol across all points → classic “adrenal fatigue” picture. Common in ME/CFS, post-COVID fatigue syndromes, and longstanding burnout. Note: this is HPA axis dysregulation, not primary adrenal insufficiency (Addison’s disease) — the DUTCH is not a substitute for a stimulation test when true adrenal insufficiency is suspected.

Pattern: High morning, low afternoon and evening → normal rhythm. This is the goal.

Pattern: Low morning, normal or high evening → reversed rhythm. Seen in shift workers, PTSD, insomnia, and chronic inflammatory conditions. Associated with immune dysregulation and metabolic syndrome risk.

4b. Free Cortisone

Cortisone is the inactive form of cortisol, interconverted by 11β-HSD enzymes. The ratio of free cortisol to free cortisone reflects the balance between 11β-HSD1 (cortisone → cortisol, activating) and 11β-HSD2 (cortisol → cortisone, inactivating).

A high cortisol/cortisone ratio suggests upregulated 11β-HSD1 activity — seen in visceral obesity and metabolic syndrome, where excess cortisol regeneration in fat tissue drives insulin resistance independent of adrenal output. This is actionable: targeted weight loss and certain plant compounds (licorice root reduces conversion; carbenoxolone blocks it) modify this ratio.

4c. Total Cortisol Metabolites (THF + 5α-THF + THE)

Cortisol metabolites — tetrahydrocortisol (THF), 5α-tetrahydrocortisol (5α-THF), and tetrahydrocortisone (THE) — represent total hepatic cortisol clearance. This is the measure most clinicians should prioritize for chronic fatigue assessment.

Key insight: Free cortisol can be low even when total production is normal if hepatic clearance is impaired. Conversely, someone can have low total metabolites (low production) but normal free cortisol if clearance is also reduced. Looking at metabolites alongside free cortisol resolves this ambiguity.

Clinical pattern: Low free cortisol + low total metabolites → genuine low production (HPA hypoactivation). Clinical pattern: Low free cortisol + normal total metabolites → normal production with increased clearance (often seen with thyroid hyperthyroidism or vigorous exercise).

4d. Cortisol Awakening Response (CAR)

The DUTCH PLUS and Complete include four salivary cortisol samples at waking, +30 min, +60 min, and bedtime. The CAR is the magnitude of cortisol rise in the first 30-60 minutes after waking.

A healthy CAR is a rise of 50-100% above waking levels. The CAR is driven by the suprachiasmatic nucleus and is largely independent of the HPA axis feedback loop — making it a sensitive biomarker of resilience and anticipatory coping. Blunted CAR is one of the most reproducible findings in ME/CFS, burnout, PTSD, and post-COVID syndrome. Restoration of CAR often precedes clinical improvement and can be used to track treatment response.

Section 5: Melatonin (MT6s)

MT6s (6-sulfatoxymelatonin) is the primary urinary melatonin metabolite. The DUTCH reports total overnight MT6s production.

Low MT6s is common in blue-light-exposed modern patients, shift workers, and anyone over 60 (production declines approximately 50% per decade after 40). In the context of the DUTCH, low melatonin alongside a disrupted cortisol rhythm confirms circadian misalignment — a pattern that responds to light therapy, chronobiotic protocols, and melatonin supplementation before sleep improvement programs.

Section 6: Organic Acid Markers (OATs)

The DUTCH Complete includes several organic acid test (OAT) markers that fall outside the hormone axes but provide cofactor and neurotransmitter context:

These OAT markers are not replacements for a full Organic Acids Test (Great Plains/Mosaic) but give rapid cofactor insight that directly informs hormone metabolism. B6, B12, and folate deficiencies impair COMT-mediated estrogen methylation — meaning no amount of I3C or DIM will optimize the 2-OH pathway if methylation cofactors are depleted.

How I Use the DUTCH Clinically

At St. George Hospital, the DUTCH Complete is part of my standard workup for patients presenting with:

• Fatigue with normal CBC, CMP, and TSH: the CAR and cortisol metabolites frequently reveal the HPA dysregulation pattern missed by standard labs
• Perimenopausal hormone assessment: progesterone metabolites and estrogen pathway ratios guide bioidentical hormone dosing more precisely than serum panels
• Breast cancer prevention counseling in high-risk women: the 2:16 ratio, 4-OHE1 levels, and methylation efficiency quantify modifiable risk
• Post-COVID recovery: cortisol awakening response and 8-OHdG are the two markers I track most closely for recovery trajectory
• PCOS differential: DHEA metabolite patterns distinguish adrenal from ovarian androgen excess, which changes management

A common mistake I see with DUTCH reports from other clinicians: treating each number in isolation rather than reading the cross-section. A low cortisol reading means nothing without the total metabolites; an elevated 4-OHE1 is only concerning in context of its methylation ratio. The DUTCH rewards the clinician who reads the full pattern.
