The DUTCH Test for PCOS: What It Measures and Whether It Changes Treatment

What Does the DUTCH Test Actually Measure?

DUTCH stands for Dried Urine Test for Comprehensive Hormones. A person collects four or five urine samples on filter-paper strips across a single day, mails them to the manufacturer’s lab, and receives a report covering estrogens, progesterone metabolites, androgens including testosterone breakdown products, and a multi-point free cortisol and cortisone curve meant to approximate the day’s cortisol rhythm. The manufacturer states the panel reports dozens of individual hormone metabolites — more than a standard blood panel lists — which is the basis of its “comprehensive” name.

Note: in May 2026, PCOS was renamed polyendocrine metabolic ovarian syndrome, or PMOS, by a global consensus of more than 50 organisations. Same condition, same diagnostic criteria — only the label changed, and that includes what counts as evidence for a test like this one. This article uses PCOS, since that is still the term most readers search.

Is the DUTCH Test the Same Thing as a Blood Test?

No — a DUTCH panel and a standard hormone blood panel use different sample types, different laboratory chemistry, and were built to answer different questions. Serum testosterone measured by liquid chromatography-tandem mass spectrometry (LC-MS/MS), or by a well-validated extraction immunoassay, is the method an Endocrine Society position statement recommends for women, specifically because standard direct immunoassays were designed and calibrated around the much higher male range and become unreliable at the low concentrations typical in women. A 2018 review in the European Journal of Endocrinology makes the same point about hyperandrogenism testing generally: the pitfalls are in assay quality and collection timing, not just in which body fluid gets tested. What a standard PCOS blood panel actually orders, and in what sequence, is worth reading before deciding whether an additional urine panel adds anything to it.

Does Any Guideline Recommend the DUTCH Test for PCOS?

No. The current international PCOS guideline directs clinicians to measure free and total testosterone from serum, using a reliable assay method, as part of confirming biochemical hyperandrogenism — one of the three Rotterdam criteria a PCOS diagnosis is actually built from. It does not mention dried urine or saliva testing anywhere in its diagnostic recommendations. Neither does the Endocrine Society’s own position statement on measuring testosterone in women, which exists specifically to steer clinicians away from assay methods that produce unreliable numbers at female-range concentrations. A test that is absent from both documents is not an oversight; it simply has not been evaluated against the standard those guidelines are built on.

Does the Manufacturer’s Own Research Support It?

This is the honest complication: most of the published research that even mentions the DUTCH test’s methodology comes from the company that sells it, Precision Analytical, and its founder is a named author. A 2026 review by that company’s own scientists — examining testosterone monitoring during hormone therapy, not PCOS diagnosis — concluded that serum remains the most accurate, validated method, that saliva testing produces misleadingly high results during transdermal hormone use, and that urine testosterone “may not be as reliable as serum,” especially in people with a common genetic variant (UGT2B17 deletion) that changes how testosterone is excreted in urine. A separate company-run study used the same lab’s own client database — a self-selected group of supplement users, with no independent serum comparison arm — to describe how DUTCH-measured urinary estrogens shift with a supplement, not to validate the panel against blood testing in a PCOS population. Even research funded and authored by the people who sell the test does not claim it outperforms serum for hormone measurement. That is a meaningfully different claim than “comprehensive.”

What About the Argument That Urine Catches More Than a Snapshot?

The case some practitioners make for DUTCH-style testing is that a single blood draw captures one moment, while urine collected across a day reflects total hormone production over that stretch of time. It is a reasonable-sounding argument, and it is not the one the evidence actually settles. A 2019 review of testosterone measurement in Maturitas walks through what actually drives inaccurate results in women: assay choice, collection timing relative to the menstrual cycle, and cross-reactivity with other steroids in cheaper immunoassays — not the sample being a single point in time. A well-timed serum sample, run on a properly validated assay, is a reliable enough snapshot for diagnostic purposes precisely because normal circulating testosterone in women does not swing wildly hour to hour the way cortisol does. The “one moment versus a full picture” framing borrows credibility from cortisol testing, where timing genuinely matters, and applies it to androgens, where the argument does not hold in the same way.

What Might the Cortisol Curve Be Useful For?

The one piece of the panel with a plausible edge over standard bloodwork is the multi-point cortisol and cortisone curve — a single serum cortisol draw only captures one moment, while four or five urine points sketch a rough daily pattern. Some functional-medicine practitioners use that curve to look at diurnal rhythm alongside other findings. Even there, though, this is not a PCOS-specific measurement, it is not part of the Rotterdam criteria, and no trial has shown that acting on a DUTCH cortisol curve changes PCOS outcomes.

Who Is the DUTCH Test Not For?

• Anyone trying to get or confirm a PCOS diagnosis. It is not part of the Rotterdam criteria and does not replace the standard hormone panel or pelvic ultrasound your workup actually needs.
• Anyone expecting results to change a treatment plan. No trial has shown that DUTCH results alter management decisions in PCOS. Guideline-based treatment — metformin, combined hormonal contraception, letrozole for fertility, lifestyle changes — is chosen from clinical findings and standard labs, not urine metabolite ratios.
• Anyone on hormonal contraception, HRT, or any exogenous hormone. Like other hormone tests, these distort results — and the manufacturer’s own published data shows non-serum testing can swing unpredictably during hormone therapy.
• Anyone price-sensitive. This panel is almost always paid out of pocket, and prices change. Check the current price directly with the lab or ordering provider rather than trust a number printed anywhere else, including here.

Should You Ever Get One Anyway?

If a functional-medicine practitioner suggests it as an add-on for exploring symptoms your standard workup has not explained, that is a reasonable thing to discuss with them — but it should sit alongside guideline-based testing, never replace it. Bring any outside results to the clinician managing your Ferriman-Gallwey scoring or hormone bloodwork so they can put the numbers in the context of what your actual diagnostic workup requires, and expect that confirming a PCOS diagnosis properly takes weeks to months regardless of which extra tests get added along the way.

Worth knowing before that conversation: DUTCH results are typically compared against ranges built from the lab’s own client population, not the diagnostic reference ranges your prescribing clinician uses for serum testosterone or DHEA-S. Two practitioners looking at the same DUTCH report can reasonably disagree about what counts as “high” or “low,” because the ranges themselves were never designed to answer a diagnostic question — they describe where a result falls relative to other people who have taken the same test, which is a different thing from a validated clinical cutoff. That distinction is easy to miss on a colourful, detailed-looking report, and it is the main reason a DUTCH result should travel with you to a clinician rather than be acted on alone.
