A complete clinical guide to Dried Urine Testing for Comprehensive Hormones — what it measures, who should be tested, how to interpret findings, and how Mitotics supports patients through every step of the process.
The DUTCH Test (Dried Urine Test for Comprehensive Hormones) is the most advanced and clinically comprehensive hormone assessment available in functional and integrative medicine. Developed by Precision Analytical Inc., the DUTCH test measures not just hormone levels but their downstream metabolites — providing a uniquely complete picture of how your body produces, uses, and clears hormones. Standard serum panels miss the majority of this information.

Standard hormone panels tell you how much of a hormone is circulating at a single moment — the DUTCH test tells you where it came from, where it's going, and whether your body is processing it safely. This is the difference between knowing that a river exists and knowing whether the dam is holding, where the water is going, and whether there are toxins in the sediment downstream.
For patients on HRT, BHRT, or with symptoms unexplained by standard labs, the DUTCH test frequently reveals the mechanism driving their presentation. Select a section from the navigation above to explore DUTCH testing in depth.
The DUTCH Complete measures 35+ hormones and metabolites across six primary hormone families. Understanding each category — and what its metabolites reveal — is essential for clinically meaningful interpretation. Unlike a simple hormone level, each metabolite is a window into enzyme function, nutrient status, genetic variants, and downstream health risk.
All steroid hormones originate from cholesterol. The DUTCH test maps production and conversion at multiple points along this cascade.
Consider two patients with identical estradiol levels. Patient A converts most of her estradiol down the 2-OH pathway, methylates it efficiently via COMT, and excretes it safely. Patient B converts a disproportionate amount down the 4-OH pathway, has impaired COMT methylation (COMT V158M polymorphism), and accumulates genotoxic 4-OH quinones in breast tissue. Standard serum panels show them as identical. The DUTCH test reveals a fundamentally different risk profile — and a clear, actionable intervention pathway (methylation support, DIM, cruciferous vegetables, targeted supplementation).
The DUTCH test is clinically indicated across a wide range of presentations — from perimenopausal women with unexplained symptoms to male patients with fatigue and low libido, athletes with HPA dysfunction, and anyone on hormone replacement therapy who needs metabolic monitoring beyond serum levels.
The gold standard for perimenopausal assessment. Captures declining estrogen AND progesterone metabolites, reveals whether estrogen dominance is present despite falling levels, and maps cortisol burden often worsening menopausal symptoms.
Serum testing cannot accurately reflect topical or transdermal HRT. The DUTCH test is the preferred and most accurate method for monitoring all forms of BHRT — ensuring therapeutic levels, preventing over/under-dosing, and tracking safety metabolites.
The 4-point cortisol diurnal pattern reveals HPA dysregulation patterns invisible to a single cortisol reading. Flat curve, inverted curve, high bedtime cortisol — each has a distinct clinical pathway and targeted intervention.
Maps the full androgen cascade in PCOS — distinguishing adrenal vs ovarian androgen sources, assessing 5α-reductase activity driving DHT (acne, hair loss), and revealing whether high androgens are primary or secondary to HPA activation.
Low MT6s (melatonin metabolite) combined with high bedtime cortisol is a common, missed pattern. Low allo-pregnanolone (progesterone metabolite) reduces GABA-A activity — a biochemical explanation for progesterone's sedative effect and sleep disruption in peri-menopause.
Free testosterone, DHEA, androstenedione, DHT metabolites — combined with cortisol pattern revealing whether HPA suppression is driving low T. Men on TRT benefit from DUTCH monitoring to assess testosterone-to-estrogen conversion and DHT levels.
The 2-OH/4-OH/16-OH estrogen metabolite profile is a direct window into estrogen-related cancer risk. The 2:16 ratio and 2-MeO:4-MeO ratio guide targeted interventions. Particularly valuable in BRCA carriers, women on estrogen therapy, and anyone with strong family history.
Total metabolized cortisol reveals total HPA output burden — often massively elevated in endurance athletes. The balance between DHEA and cortisol (anabolic/catabolic ratio) is a precise recovery and adaptation marker not visible in standard labs.
High cortisol patterns on DUTCH directly suppress TSH and impair T4→T3 conversion. Patients with normal thyroid panels but persistent hypothyroid-like symptoms often have high cortisol as the primary driver — an intervention pathway missed without DUTCH.
DUTCH is not appropriate for all patients or clinical scenarios. The following situations require different testing approaches or clinical context adjustments before ordering.
Precision Analytical offers several DUTCH test variants — each optimized for different clinical scenarios. Selecting the right test version is essential for getting actionable data without unnecessary cost. Mitotics helps patients identify the most appropriate version based on their clinical presentation.
Mitotics Clinical Recommendation: For most patients seeking a comprehensive first assessment, the DUTCH Complete provides the best balance of clinical depth and value. DUTCH Plus is recommended when there is any suspected nutritional depletion, chronic fatigue, or when oxidative stress markers are clinically relevant. Cycle Mapping is reserved for premenopausal patients with cycle-specific concerns or fertility workup.
The DUTCH test uses a simple dried urine collection method — 4 to 5 filter paper strips saturated with urine over a 24-hour period. Unlike blood draws, the collection is done entirely at home, on the patient's own schedule. Understanding how to do this correctly is critical — collection errors are the most common source of inaccurate results.
4 urine collections over 24 hours. All done at home. Results typically returned within 5–7 business days.
Collect at bedtime (10pm–midnight). Urinate on strip for 5 sec, let dry fully overnight. This is also the melatonin sample.
Collect immediately upon waking — before eating, drinking, or exercise. First CAR sample.
Second CAR sample — 30 minutes post-waking. Critical for measuring cortisol awakening response (CAR spike).
Collect between 11am and 1pm. Normal activity day — avoid intense exercise the day of collection.
Collect between 4pm and 6pm. Continue same low-stress day. All strips air dry for 24h before mailing.
Mail prepaid kit. Results in 5–7 business days. Online portal + practitioner report. Mitotics interprets with you.
Certain substances interfere with DUTCH results and require specific timing or avoidance:
The correct day of collection is the single most important variable for premenopausal women:
The collection day should represent a typical day — not an extreme. These factors distort cortisol patterns:
Urine concentration directly affects all DUTCH measurements. Precision Analytical applies creatinine correction but extreme dilution affects accuracy:
DUTCH test interpretation requires clinical training and integration with the patient's full picture — symptoms, medications, cycle phase, lifestyle, and other lab findings. The raw report contains over 35 data points; clinically meaningful interpretation means understanding which patterns are driving symptoms and which interventions are most likely to shift them.
High morning → gradual decline → low bedtime. The CAR spike (30–45 min post-wake) should be 50–100% above baseline. Total metabolized cortisol in the mid-reference range. This pattern reflects healthy HPA resilience, good stress adaptation, and intact circadian rhythm. Sleep should be normal. Energy/mood typically stable throughout the day.
Low across all four time points. Minimal or no CAR. Total metabolized cortisol also low. Classic "adrenal fatigue" pattern (more accurately: HPA hypoactivation or downregulation). Associated with severe burnout, prolonged stress, chronic illness, morning non-function, inability to exercise, salt cravings, dizziness on standing. DHEA:cortisol ratio should be checked — often DHEA is also low. Intervention: cortisol support, adaptogenic herbs, sleep prioritization, pacing.
High across multiple time points. High total metabolized cortisol. Often with high bedtime cortisol. Pattern of chronic activation — body stuck in high-output state. Associated with anxiety, insomnia, difficulty relaxing, abdominal weight gain, high blood pressure, immune suppression, and insulin resistance. This pattern suppresses thyroid function and sex hormone production. Intervention: HPA downregulation, phosphatidylserine, ashwagandha, sleep hygiene, parasympathetic activation.
Low morning, high afternoon/evening. Disrupted circadian regulation. Associated with night shift workers, chronic pain, and late-stage burnout. These patients often feel their best late at night and worst in the morning. Evening cortisol elevation drives insomnia and prevents natural sleep onset. Melatonin suppression is common in this pattern. Intervention: light therapy, morning cortisol stimulation, strict sleep hygiene, blue light elimination at night.
Normal daytime, high bedtime cortisol. Extremely common pattern in modern high-stress individuals. Often presents as "can't wind down," lying awake with racing thoughts, difficulty transitioning from work to rest. Cortisol should be at its physiological nadir at bedtime to allow melatonin rise. When elevated at bedtime, melatonin is suppressed and sleep onset is delayed. Intervention: evening routine structure, dinner timing, phosphatidylserine, cortisol-modulating adaptogens (Relora, ashwagandha).
High 2-OH estrone. High 2-MeO estrone. Low 4-OH. Low 16-OH. Optimal detoxification pathway. 2-OH estrone is the preferred clearance route — anti-proliferative. High 2-MeO indicates functional COMT enzyme activity (adequate magnesium, B2, SAMe). This pattern is associated with lower estrogen-sensitive cancer risk. Common in patients with adequate cruciferous vegetable intake and methylation nutrient sufficiency.
Elevated 4-OH estrone. Low 4-MeO estrone. The 4-OH estrone pathway generates catechol estrogens capable of forming genotoxic quinones that can directly adduct DNA — particularly in breast and endometrial tissue. COMT methylation of 4-OH to 4-MeO is the protective step: if 4-MeO is low despite elevated 4-OH, COMT is insufficient. COMT V158M polymorphism is the most common cause. Intervention: methyl donors (methylfolate, methyl-B12, SAMe), magnesium, DIM, sulforaphane, I3C.
High E1/E2 relative to progesterone. High 16-OH estrone. Estrogen dominance is a ratio problem — not always an absolute elevation. It can occur with normal or even low estrogen if progesterone is proportionally lower. Symptoms: heavy periods, breast tenderness, bloating, mood instability, weight gain at hips. 16-OH dominance (without 4-OH elevation) is less genotoxic but more proliferative — associated with uterine fibroid growth and endometriosis. Intervention: DIM, fiber (microbiome estrogen recirculation), liver support, weight management (adipose aromatization).
Low E1, E2, E3. Minimal metabolites throughout. Postmenopausal or hypoestrogenic presentation. Estrogen insufficiency drives hot flashes, vaginal atrophy, cognitive changes, bone loss, cardiovascular risk, and mood disruption. When estrogen is this low, metabolite ratios become less clinically urgent — the primary intervention is establishing adequate estrogen levels before optimizing pathway ratios. HRT is the foundation; DUTCH monitoring then guides metabolic safety.
Before ordering a DUTCH test — or helping a patient proceed with one — there are critical clinical, analytical, and contextual considerations that determine whether the results will be interpretable, accurate, and actionable. These are the conversations that separate a well-ordered test from an expensive piece of paper.
The form of hormone therapy a patient is using fundamentally changes how DUTCH results must be interpreted:
The gut microbiome significantly modulates estrogen levels through the estrobolome — a subset of gut bacteria producing β-glucuronidase enzyme:
Several common genetic variants directly affect DUTCH interpretation:
All hormone metabolites require hepatic Phase I and Phase II detoxification. Impaired liver function distorts every section of the DUTCH report:
The DUTCH cortisol diurnal pattern is highly sensitive to the prior sleep environment:
Body composition meaningfully influences DUTCH estrogen results:
Several common supplements directly affect DUTCH results — clinicians and patients must be aware:
The DUTCH test provides maximum value when used serially to track intervention response:
The Most Overlooked Consideration: A DUTCH test ordered without a trained interpreter is a waste of resources. The raw Precision Analytical report contains clinical recommendations, but it cannot integrate the patient's full clinical picture, medication list, genetic context, and symptom presentation. Mitotics provides complete, personalized DUTCH interpretation as part of our service — ensuring every data point is translated into actionable clinical guidance.

A single test is a snapshot. We build your longitudinal hormone monitoring calendar — tracking response to interventions and identifying when patterns are shifting toward or away from optimal health.
Intervention target: COMT enzyme support. Methylfolate (5-MTHF) 400–800 mcg/day, methylcobalamin (B12), SAMe 400–800 mg, magnesium glycinate 300–400 mg (COMT cofactor), riboflavin (B2) 25–100 mg (COMT cofactor). DIM 150–300 mg/day (shifts toward 2-OH pathway). Cruciferous vegetables (broccoli sprouts for sulforaphane). COMT V158M genetic variant suggests lifelong need for these interventions. Retest at 3 months to confirm methylation improvement.
Intervention target: HPA downregulation without suppression. Phosphatidylserine 200–400 mg/day (cortisol blunting effect, well-validated in RCTs). Ashwagandha KSM-66 300–600 mg (most evidence for cortisol modulation). Relora (magnolia + phellodendron) for high bedtime cortisol specifically. L-theanine 200–400 mg (anxiolytic without sedation). Prioritize sleep architecture, parasympathetic activation practices, and HPA load reduction (exercise calibration, boundary setting). Rule out thyroid dysfunction and insulin resistance as co-drivers.
Intervention target: HPA support and restoration. Adaptogens that support (not suppress) cortisol: Rhodiola rosea 200–400 mg AM (energizing adaptogen), eleuthero, licorice root (short-term, elevates cortisol via 11β-HSD inhibition). Salt loading (unrefined salt) for orthostatic symptoms. Vitamin C 500–1000 mg (adrenocortical support). Rule out primary adrenal insufficiency with AM cortisol and ACTH stimulation testing first. Pacing, gradual exercise reintroduction, sleep non-negotiable. This pattern requires the most time to resolve — typically 6–12 months of consistent intervention.
Intervention target: 5α-reductase inhibition. Saw palmetto extract (standardized 85–95% fatty acids) 320 mg/day. Zinc 30–50 mg/day (5α-reductase inhibitor). Lycopene (tomato extract) — anti-androgenic at prostate tissue. Beta-sitosterol. Spearmint tea (anti-androgenic effect in women). In men: discuss finasteride/dutasteride with prescriber if DHT-driven hair loss or prostate symptoms are significant clinical concerns. Nettle root (supports SHBG, reduces free androgen). Iron out PCOS vs adrenal androgen source — determines treatment approach.
Intervention target: progesterone pathway support and oral route consideration. If serum/DUTCH progesterone is low: bioidentical progesterone (prescription) is the foundation. Route matters: oral micronized progesterone (Prometrium) converts more to allo-pregnanolone centrally than transdermal cream — patients with anxiety, PMDD, or sleep as primary concern often prefer oral route. Magnesium glycinate reduces neuronal excitability (GABA support, independent mechanism). Taurine, glycine, L-theanine support GABAergic tone. Discuss progesterone timing: taking progesterone at bedtime leverages its sedative effect via allo-pregnanolone.
Intervention target: circadian restoration and melatonin support. Blue light blocking glasses after 8pm. Strict sleep-wake consistency (within 30 minutes). Eliminate screens from bedroom. Melatonin supplementation: 0.5–3 mg immediate-release for sleep onset, time-release for sleep maintenance. Tryptophan/5-HTP (serotonin → melatonin precursor) — with caution if on SSRIs. Ensure dark sleep environment (blackout curtains). Morning bright light (10,000 lux, within 30 min of waking) anchors the circadian clock and indirectly improves nighttime melatonin output.
