DUTCH Test

Also known as:

Dried Urine Test for Comprehensive Hormones

The DUTCH test (Dried Urine Test for Comprehensive Hormones) maps sex hormones, cortisol rhythm, and metabolites that standard blood and saliva testing miss.

SLOT: Full Definition

What the DUTCH test measures

The DUTCH test — short for Dried Urine Test for Comprehensive Hormones — is a specialty hormone test performed on dried urine samples collected over 24 hours. Unlike a standard blood draw, which captures a single moment, DUTCH measures hormones and their metabolites across the day, giving a much more complete view of how the body produces and processes hormones.

A standard DUTCH panel covers:

  • Sex hormones: estrogen (E1, E2, E3), progesterone, testosterone, DHEA, and their metabolites
  • Cortisol rhythm: 4 timed cortisol readings plus cortisone — the full diurnal curve
  • Estrogen metabolism pathways: the 2-OH, 4-OH, and 16-OH pathways and how well your body methylates them
  • Androgen metabolites: including 5-alpha vs 5-beta pathways, which clarify Polycystic Ovary Syndrome and androgen excess
  • Organic acids (on the DUTCH Plus): markers of B vitamin status, neurotransmitter turnover, and oxidative stress

At Modern Thyroid Clinic, DUTCH is one of the most useful tools we have when sex hormones, cortisol, and detoxification all need to be evaluated together — particularly in perimenopause, Estrogen Dominance, unexplained fatigue, and persistent hormone symptoms despite normal blood labs.

Why it matters

Blood tests for estrogen and progesterone show only the 'parent' hormone at one moment. They cannot tell you:

  • Whether you are metabolizing estrogen down a protective or potentially carcinogenic pathway
  • Whether your cortisol rhythm rises and falls correctly through the day
  • Whether testosterone is being shunted into DHT (linked to acne and hair loss)
  • How well methylation is clearing used-up hormones

These pathways matter clinically. Two women with identical estradiol levels can have very different breast cancer risk, mood, and perimenopause symptom profiles depending on how they metabolize estrogen.

Reference range vs. functional/optimal range

DUTCH provides its own reference ranges based on sex, age, and menopausal status, with functional targets layered on top. There is no single 'normal' number — interpretation is pattern-based, looking at:

  • Estrogen metabolism balance (favoring the 2-OH pathway)
  • Adequate methylation of metabolites
  • A robust morning cortisol awakening response with a smooth decline
  • Appropriate progesterone-to-estrogen ratio for cycle phase or menopausal status

What abnormal results suggest

A DUTCH test can reveal estrogen dominance, poor estrogen detoxification, low progesterone, androgen excess driving acne or hair loss, blunted or reversed cortisol rhythm, and B-vitamin or methylation issues feeding into hormone problems. It is particularly useful when standard labs are 'normal' but symptoms are not — and when planning bioidentical hormone therapy, because the metabolite picture often guides which form (oral, transdermal, vaginal) is safest for an individual woman. Results should always be interpreted with a clinician trained in functional hormone testing.

Common questions

DUTCH vs. blood vs. saliva — which is best?

Each has a place. Blood is best for thyroid, fasting metabolic markers, and a one-time snapshot of total hormone levels. Saliva is good for the cortisol curve and free (unbound) hormones. DUTCH offers the most comprehensive view — free hormones plus metabolites plus the cortisol curve in one panel — which is why we use it heavily in perimenopause and complex hormone cases. None of them replaces a thoughtful clinical history. The right test depends on the question being asked, which is why we choose testing case by case rather than running everything reflexively.

When in my cycle should I test?

If you are still cycling, DUTCH is best collected during the **luteal phase**, ideally days 19–22 of a 28-day cycle (or about a week before your expected period). This is when progesterone peaks and the estrogen-to-progesterone relationship is most clinically informative. If you are in perimenopause with irregular cycles, your clinician can help time the test or use a cycle-mapping version. In menopause or on continuous hormone therapy, timing matters less — collection can happen on any day.

Is the DUTCH test covered by insurance?

DUTCH is typically not covered by insurance and is paid out of pocket. Pricing varies by panel, with the DUTCH Complete and DUTCH Plus being the most commonly ordered. Many patients find the depth of information justifies the cost, especially when standard labs have not explained their symptoms or when planning hormone therapy. At MTC we only order DUTCH when we believe it will meaningfully change the treatment plan — not as a routine screen — so the cost translates into actionable answers.
