Most hormone panels give you a snapshot. The DUTCH gives you the story. Here's why that difference matters more than most people realize — and how I use it in practice.
I've been practicing integrative and functional medicine for over 18 years, and if there's one thing I've learned, it's that a single hormone number tells you almost nothing.
I can't tell you how many patients have walked into my office carrying a thyroid panel, a basic estradiol level, and a testosterone reading — and a doctor who said "everything looks normal." Meanwhile, they're exhausted, gaining weight around the middle, sleeping terribly, and feeling like a stranger in their own body.
The problem isn't always that the hormones are deficient. Sometimes the problem is what your body is doing with them.
That's exactly what the DUTCH test is designed to show. It's one of the most clinically useful tools I have for patients whose standard labs come back unremarkable — but who are anything but fine.
If you've been told your hormones are normal and you've accepted that answer — I want you to know there is likely more to the story.
DUTCH stands for Dried Urine Test for Comprehensive Hormones. It was developed by Precision Analytical and has become one of the most valuable tools in my practice for building a complete hormonal picture — one that standard blood draws simply can't provide.
Instead of a single blood draw at a single point in time, you collect dried urine samples over the course of 24 hours — a few filter paper strips at specific intervals throughout the day. You mail them to the lab and results come back typically within two to three weeks.
It's not complicated. And what it shows is far more nuanced than most panels I've seen.
The critical distinction — and the reason I reach for this test over standard blood work in many situations — is that the DUTCH doesn't just measure hormone levels. It measures hormone metabolites. And that difference changes everything about what we're actually able to see.
The DUTCH test is comprehensive in a way that changes the clinical picture. Here's what it gives me that I can't get anywhere else.
Estrogen, progesterone, androgens including testosterone and DHEA — those are all here. But the DUTCH also shows how your body is metabolizing estrogen. There are several estrogen metabolites, and some are protective. Others — particularly when they're high and not being cleared effectively — are associated with a higher risk of hormone-related conditions. This is information you simply cannot get from a standard estradiol level.
This is where things get really interesting. The DUTCH gives me a cortisol pattern throughout the day — not just a single reading. Adrenal dysfunction is rarely about flatly high or low cortisol. It's about the rhythm being off. You can have average cortisol that looks acceptable on paper, but a pattern that shows you wake up exhausted, crash at 2pm, and then get a second wind at 11pm that keeps you from sleeping. That pattern shows up here.
Sleep disruption is one of the most common complaints I hear, particularly in women going through perimenopause. The DUTCH includes a melatonin marker that adds one more data point when sleep is part of the clinical picture. When someone is exhausted but can't stay asleep, or wakes at 3am every night without fail, having that marker matters.
This is the piece most people don't expect. The DUTCH also includes select organic acid markers — indicators for B vitamin status, glutathione production, and neurotransmitter metabolism. When I see a patient with unexplained fatigue, mood changes, or poor stress resilience, these markers often point me in the right direction when everything else looks normal.
I want to stay on this point because it's the core of why I find this test so valuable.
Say a woman's estradiol comes back in normal range on a standard blood test. Her doctor says she's fine. But on the DUTCH, I can see that she's shunting estrogen down a pathway that produces a more aggressive, less favorable metabolite — and her methylation markers, which help clear that metabolite, are suboptimal. Her number looked fine. What her body was doing with that number was not.
Or consider a patient whose total cortisol looks acceptable, but the pattern shows she's dumping cortisol in the evening when it should be low — keeping her wired, anxious, and completely unable to wind down at night. She's been told she doesn't have adrenal fatigue because her number is normal. But the rhythm tells a very different story.
This is the kind of clinical picture I need to build a truly personalized protocol. Hormone metabolite patterns inform how I approach estrogen metabolism support, methylation, liver detox pathways, and adrenal restoration. Without that, I'm working with half the map.
It's not that previous testing was wrong. Standard testing was designed to answer different questions than the ones functional medicine asks. The DUTCH just lets us ask more of them.
I order the DUTCH when standard labs haven't given us enough to work with, or when the clinical picture warrants a deeper look at hormonal patterns. These are the situations that come up most often in my practice.
Honesty matters more to me than selling a test. So here's the part I always make clear with my patients.
The DUTCH is not a standalone diagnostic. It doesn't replace bloodwork for thyroid function, FSH, LH, blood glucose, or a full metabolic panel. I use it alongside traditional testing, not instead of it. If you're new to my practice, we're still going to build a complete clinical picture — and that includes standard labs.
The results also require careful clinical interpretation. This is not a test you should order on your own through a direct-to-consumer service and then try to make sense of from a Google search. The patterns are nuanced, and context matters enormously — your age, where you are in your cycle if you're still cycling, your symptoms, your history, your current medications and supplements.
In my practice, DUTCH results inform the conversation. They tell me where to dig deeper. They explain the "why" behind symptoms that looked like a mystery on standard labs. That's exactly what I need them to do — and in the right hands, they do it well.
That's the message I want to leave you with. "Normal" on a standard hormone panel is not the same as optimal. And optimal is what we're after.
The DUTCH test is one of the tools I use to ask better questions — and get real answers about what's actually driving your symptoms. When we understand not just your hormone levels but how your body is processing and clearing those hormones, we can build a protocol that actually makes sense for your specific biology.
Whether you're navigating perimenopause, struggling with fatigue and broken sleep, managing PCOS, dealing with estrogen-related symptoms that no one has been able to explain, or already on hormone therapy and wondering if your protocol is truly dialed in — this kind of testing is often the piece that finally makes the picture clear.
If it sounds like it might be relevant to what you're experiencing, I'm happy to talk through whether it makes sense for you. That's what the inquiry call is for.
How do I collect the sample?
The DUTCH test uses dried urine, not blood or saliva. You collect urine samples at four points over one day by saturating filter paper strips and letting them dry. The kit includes instructions, and Dr. Sherri's team walks you through the process before you start.
Is the DUTCH test covered by insurance?
Most insurance plans do not cover the DUTCH test. It is a cash-pay functional lab. The cost is discussed during your consultation with Dr. Sherri.
How is this different from a standard hormone panel?
A standard panel shows hormone levels at a single point in time. The DUTCH measures hormone metabolites — how your body is actually processing and clearing those hormones — along with your cortisol pattern across the day. It answers questions that standard blood testing was not designed to ask.
Can I do the DUTCH test if I'm on hormone therapy?
Yes, and it is often very useful if you are. The DUTCH can show how your body is metabolizing exogenous hormones and whether your dosing and delivery method are working. Timing matters, and Dr. Sherri will give you specific guidance based on your protocol.
When in my cycle should I collect the sample?
For pre-menopausal women with regular cycles, the ideal window is days 19 to 22 of a 28-day cycle. For post-menopausal women or those without a regular cycle, timing is more flexible. Dr. Sherri will advise based on your situation.
