What Is the DUTCH Test — and Why Is It Better Than a Standard Blood Panel?
Standard hormone blood panels give you a snapshot
what your hormone levels look like at a single point in time, in the bloodstream. The DUTCH test does something more complex and more clinically useful: it shows what happens after those hormones enter your cells and how your body is breaking them down. For many patients, this is the difference between a partial answer and a complete picture.
What is the DUTCH test?
DUTCH stands for Dried Urine Test for Comprehensive Hormones. It is a hormone testing method that uses dried urine samples — collected at specific times over a 24-hour period to measure both hormone levels and their downstream metabolites. Unlike a single blood draw, the DUTCH test captures the pattern of cortisol and sex hormone activity across the day and analyzes how the body is processing and excreting those hormones. This reveals information about estrogen metabolism pathways, adrenal function, and hormone imbalances that standard blood tests simply cannot capture.
What Does the DUTCH Test Measure?
The DUTCH test measures a comprehensive panel including:
Sex hormones and their metabolites:
Estradiol, estrone, estriol — and critically, their metabolic breakdown products (2-OH, 4-OH, 16-OH estrogens), which indicate whether estrogen is being metabolized through protective or potentially problematic pathways
Progesterone metabolites
Testosterone and its metabolites (including DHT conversion)
DHEA and DHEA-S
Adrenal hormones:
Free cortisol — across four collection points to reveal the diurnal cortisol rhythm (how cortisol rises and falls through the day), not just a single level
Cortisone — the inactive form cortisol converts to
DHEA as an adrenal marker
Organic acids (in extended panels):
Markers of B12, B6, and glutathione status
Melatonin metabolite (to assess sleep quality)
Oxidative stress markers
Neurotransmitter metabolites (dopamine, norepinephrine, serotonin)
How Is the DUTCH Test Different From a Blood Test?
Why is the DUTCH test better than a standard hormone blood panel?
Blood tests measure the amount of hormone circulating in the bloodstream at a single moment. This misses several critical dimensions:
Hormone metabolism: Blood tests show how much estrogen you have. The DUTCH test shows which estrogen metabolic pathway your body is using — and some pathways are associated with increased cancer risk while others are protective. This matters enormously for clinical decisions about hormone therapy.
Cortisol rhythm: A single cortisol blood draw tells you your cortisol level at that moment. The DUTCH test's four-point collection maps whether your cortisol rises appropriately in the morning, sustains through the day, and falls at night — or whether it's flat, inverted, or dysregulated in a pattern that explains fatigue, anxiety, sleep problems, or immune suppression.
24-hour picture vs. snapshot: Hormones fluctuate. A single blood draw can be misleading depending on time of day, recent stress, sleep quality the night before, and where a woman is in her cycle. The DUTCH test's multi-point urine collection captures a more representative picture.
Tissue-level activity: Urine metabolites reflect what happened after hormones were processed inside cells — giving insight into intracellular hormone activity that blood levels don't reveal.
Who Should Consider the DUTCH Test?
At DNA Wellness, Dr. Katherine Ortiz uses the DUTCH test for patients who:
Are experiencing symptoms of hormone imbalance but have been told their blood work is normal
Are already on hormone therapy and want to confirm hormones are being metabolized appropriately (particularly important for estrogen safety monitoring)
Have unexplained fatigue, anxiety, sleep disruption, or mood instability that hasn't been explained by standard testing
Are dealing with PMS, PMDD, irregular cycles, or suspected estrogen dominance
Want a baseline comprehensive hormonal assessment before starting any hormone or peptide protocol
Are concerned about estrogen metabolism and breast cancer risk
How Do You Do the DUTCH Test?
The collection process is straightforward. Patients receive a test kit with filter paper strips and instructions. Urine is collected at four to five time points over a 24-hour period — morning, evening, and overnight — by urinating onto the strips, which are then dried and mailed to the DUTCH laboratory. Results are typically returned within 5–7 business days.
At DNA Wellness, Dr. Ortiz reviews DUTCH results in the context of your full clinical picture — symptoms, health history, and any concurrent blood work — rather than interpreting the numbers in isolation. The test generates substantial information; the clinical value is in knowing how to apply it.
Frequently Asked Questions About the DUTCH Test
Is the DUTCH test covered by insurance? The DUTCH test is typically not covered by standard insurance plans and is an out-of-pocket cost. Contact DNA Wellness directly for current pricing.
How accurate is the DUTCH test compared to blood tests? The DUTCH test and blood tests measure different things — they are complementary rather than directly comparable. Blood tests reflect circulating hormone levels; the DUTCH test reflects hormone metabolism and adrenal rhythm. Both have clinical validity. For patients on hormone therapy or those with complex hormone symptoms, the DUTCH test often provides clinically actionable information that blood testing alone does not.
Can men take the DUTCH test? Yes. The DUTCH test is valuable for men as well — particularly for assessing cortisol rhythm, adrenal function, testosterone metabolism (including DHT conversion, which is relevant for hair loss and prostate health), and estrogen metabolism.
Do I need to stop hormone therapy before taking the DUTCH test? Not necessarily. The DUTCH test can be run both before and during hormone therapy. When run during therapy, it helps confirm that hormones are being absorbed, metabolized, and cleared appropriately — which is important for safety monitoring, particularly with estrogen. Dr. Ortiz will advise on timing based on your specific situation.
How long does it take to get DUTCH test results? Results are typically returned within 5–7 business days of the lab receiving the sample. A follow-up consultation is scheduled to review results and apply them to your protocol.
If you've had hormone symptoms that standard blood work hasn't explained — or you want a comprehensive view of how your body is processing hormones before or during therapy — the DUTCH test at DNA Wellness and Longevity Institute in Bonita Springs offers the depth of information that changes clinical decisions.
