DUTCH Complete

A standard blood draw can tell you how much estrogen or testosterone is circulating right now. What it cannot tell you is what happens next. Your body breaks hormones down through specific chemical pathways, and the route matters. Two people with identical blood estrogen levels can face very different health risks depending on which breakdown pathway dominates. The same logic applies to cortisol: a single morning blood draw captures one snapshot, but your stress hormone system operates on a 24-hour rhythm that one reading cannot reveal.

The DUTCH Complete (Dried Urine Test for Comprehensive Hormones) captures this fuller picture. By collecting four dried urine samples across a single day, it measures not only your hormone levels but also how your body breaks them down, how your adrenal rhythm behaves from morning to bedtime, and whether key nutrient helpers are sufficient to keep those pathways running properly.

What This Panel Reveals

The panel covers five distinct clinical domains, each telling a different chapter of the same story. Together they explain how your hormonal system is functioning as a whole, from production through processing to elimination.

Estrogen Production and Metabolism

Your body makes three forms of estrogen. The panel measures all three, but the real value lies in the next layer: the breakdown products. Estrogen is processed through three main pathways, each involving a chemical modification called hydroxylation, where the body adds an oxygen-hydrogen group at a specific position on the estrogen molecule. The 2-hydroxylation pathway is generally considered the most favorable. The 4-hydroxylation pathway produces breakdown products that can directly damage DNA by forming highly reactive compounds. The 16-hydroxylation pathway creates a breakdown product with strong estrogenic activity that stays active longer than the parent hormone.

In a large European prospective study (EPIC cohort) of postmenopausal women, those with more activity through the 2-hydroxylation pathway relative to the 16 pathway had a lower risk of breast cancer. The ratio between these pathways matters because it reflects the balance between less active and more active estrogen breakdown products. The panel also measures whether methylation, a protective chemical tagging step that neutralizes the reactive 2- and 4-hydroxylated breakdown products, is keeping pace. If the 2-methoxy metabolite is low relative to the 2-hydroxy metabolite, methylation may be lagging behind.

Androgen Production and Metabolism

Blood testosterone tells you the supply. Dried urine tells you what your body does with it. Testosterone can be converted by an enzyme called 5-alpha-reductase into its more potent form, 5-alpha-DHT (dihydrotestosterone), or it can be inactivated through a different route. The panel shows both pathways. In women, this matters for acne, hair thinning, and polycystic ovary syndrome (PCOS). Research using urinary androgen profiles in women with PCOS has revealed abnormal 5-alpha-reductase activity that serum testosterone alone did not detect. In men, the balance between testosterone, DHT, and their downstream breakdown products helps clarify whether symptoms stem from low production, excessive conversion, or rapid clearance.

The panel also measures DHEA-S (dehydroepiandrosterone sulfate), the most abundant androgen precursor made by the adrenal glands. DHEA-S declines steadily with age, dropping roughly 80% between ages 25 and 75 in both sexes. Tracking it alongside downstream androgens shows whether the adrenal contribution to your androgen pool is adequate.

Progesterone Metabolites

Serum progesterone is notoriously unreliable for confirming ovulation or assessing luteal phase (the second half of the menstrual cycle, after ovulation) adequacy, because it fluctuates in pulses throughout the day. Urine metabolites of progesterone (pregnanediol) reflect cumulative production over hours rather than a single pulsatile moment. This makes the dried urine measurement more stable and, in many clinical contexts, more informative for evaluating whether ovulation occurred and whether progesterone output was sufficient.

The Cortisol Story: Rhythm, Total Output, and Clearance

Cortisol follows a predictable daily curve: highest shortly after waking, declining through the afternoon, and reaching its lowest point around midnight. The panel captures this rhythm across four time points. But it adds two layers that saliva testing alone does not provide.

First, it measures cortisone alongside cortisol at every time point. Cortisone is the inactive storage form of cortisol, and the ratio between them reflects the activity of an enzyme called 11-beta-HSD that converts one to the other. If cortisol is low but cortisone is high, the issue may not be low production but excessive inactivation. This distinction changes the clinical approach entirely.

Second, it measures total metabolized cortisol, the sum of cortisol breakdown products processed by the liver. Some people show low free cortisol on saliva tests but normal or high metabolized cortisol, meaning their adrenals are producing plenty but their liver is clearing it rapidly. Without the metabolized cortisol measurement, these individuals might be misdiagnosed with adrenal insufficiency.

Nutrient and Neurotransmitter Markers

The panel includes a set of organic acid markers that act as functional nutrient sensors. Methylmalonate rises when vitamin B12 is insufficient at the cellular level, even when serum B12 looks normal. Research on elderly populations has shown that a meaningful proportion of those with serum B12 in the low-normal range have elevated methylmalonate, indicating functional deficiency that standard blood tests miss. Xanthurenate is a marker of vitamin B6 status, and pyroglutamate reflects demand for glutathione, a protective molecule your body uses to neutralize harmful compounds. These nutrients serve as essential helpers for the hormone metabolism pathways measured elsewhere in the panel. If B6 is low, for example, the methylation step that neutralizes reactive estrogen breakdown products may be impaired.

Homovanillate (HVA) and vanilmandelate (VMA) are breakdown products of the brain chemicals dopamine and norepinephrine, respectively. Their ratio provides a window into the balance between these two chemical messengers. The melatonin metabolite (6-hydroxy-melatonin-sulfate) reflects overnight melatonin production, connecting sleep quality to the hormonal picture.

How to Read Your Results Together

The real power of this panel is pattern recognition. Individual values matter, but the combinations tell the clinical story. Here are the most actionable patterns to look for.

When Results Can Be Misleading

Hydration status directly affects dried urine concentration. The panel includes creatinine at each collection point to adjust for this, but extreme dehydration or overhydration can still skew results. Oral contraceptives suppress the body's own hormone production and will produce artificially low values across most sex hormone metabolites. Bioidentical hormone replacement will elevate specific metabolites depending on the formulation and route of administration, so results must be interpreted in that context.

Acute illness, poor sleep the night before collection, or unusual physical stress can alter cortisol rhythm and neurotransmitter metabolites for that day. If your collection day was atypical, consider retesting. High-dose biotin supplements can interfere with some testing methods, though this is less of a concern with the analytical methods used in dried urine panels.

Working with Your Results

Many findings from this panel, particularly the nutrient markers, are directly addressable with targeted supplementation that can be confirmed on retesting. Unfavorable hormone metabolism patterns and cortisol rhythm abnormalities warrant discussion with a practitioner trained in functional or integrative endocrinology. The dried urine methodology and metabolite ratios are not yet part of standard conventional endocrinology guidelines, so choosing a provider who understands the test format matters.
