Many conventional hormone tests use a single blood sample taken at one point in the day, which takes a snapshot but misses the bigger picture of how hormones rise, fall, and metabolize over 24 hours. The DUTCH test was developed to bridge that gap. What it actually measures, how it differs from conventional testing and where its real value lies
DUTCH = Dried Urine Test for Complete Hormones. Rather than a single blood draw, it utilizes multiple dried urine samples taken at predetermined times over an entire day, enabling the detection of patterns, such as the diurnal variation of cortisol, rather than a solitary figure.
The core panel includes sex hormones (estrogen, progesterone, testosterone) and their metabolites (breakdown products). It also monitors the cortisol rhythm during the day, following the natural morning rise and evening decline that a single blood draw can’t show. Depending on the panel ordered, it may also include markers such as melatonin or organic acid markers related to nutrient and neurotransmitter metabolism.
A blood or saliva test generally measures a snapshot of hormone levels. The multiple timed samples of the DUTCH test show the hormone pattern over the day, which can be particularly useful for assessing cortisol, where a flat or inverted pattern can differ greatly from a single high or low reading. It also measures hormone metabolites — the byproducts of how the body breaks down hormones — which standard panels typically don’t report at all.
Results can highlight relevant patterns: a blunted or inverted cortisol rhythm, sex hormone levels outside the applicable reference range, or a pattern of metabolites that indicates hormones are being processed in a particular way. These patterns are often considered alongside other symptoms, such as ongoing tiredness, sleep problems, mood changes, or irregular cycles, to get a fuller picture of what might be causing them.
Let's be clear here: the DUTCH test is not a diagnostic test. It does not diagnose conditions such as PCOS, thyroid disorders, adrenal insufficiency or endometriosis, and the results are not a substitute for the traditional medical testing needed for those conditions. It provides detailed hormone and metabolite patterns that must be interpreted in context—it does not provide a diagnosis. But the real value lies in interpreting those patterns in light of a person’s real symptoms and health history—not in the raw numbers alone.
A DUTCH panel by itself is just data. What makes it useful is the interpretation, cross-referenced with symptoms, history, and other testing, to find patterns that might contribute to fatigue, mood changes, cycle irregularities, or other persistent symptoms. That’s where a functional medicine approach is different from just ordering the test: the results are one piece of a larger puzzle, not an answer in and of themselves.
A DUTCH test can show patterns that regular blood work will not detect—especially when it comes to cortisol rhythm and hormone metabolism. The value of the data depends entirely on the context in which you interpret them. The first step in using the test well is to know what it can and cannot tell you.
Infinity Wellness takes a holistic and evidence-based approach to hormone and metabolic health, using tools like the DUTCH test as part of a broader effort to identify factors that may contribute to persistent symptoms, rather than treating them in isolation. If you’ve been trying to understand persistent fatigue, mood changes, sleep issues or hormone-related symptoms, contact Infinity Wellness to see if DUTCH testing is right for your evaluation.
No. The DUTCH test is not a diagnostic test for PCOS, thyroid disease, or other similar endocrine disorders; these require appropriate clinical evaluation and diagnostic testing. It can provide information on your hormone and metabolite patterns that can add context to those evaluations, but it is not a diagnosis on its own.
Most blood tests measure hormone levels at a single point in time. The DUTCH test involves taking samples throughout the day, which can show the rhythm of hormones like cortisol, and it includes metabolite information we don’t get from a standard blood panel.
The most common reasons people come in for hormone testing as part of a larger workup are complaints of constant tiredness, poor sleep, mood swings and irregular cycles. It is usually used alongside symptoms and history rather than as a single test.
