DUTCH Test vs Blood Test: Which Hormone Test Do You Need?

Blood, dried urine and saliva measure different things. Blood measures the hormone circulating when it is drawn. DUTCH measures what you made and processed over the preceding hours. Saliva measures the free fraction in one fluid at one moment, with caveats that make it the least useful of the three. For most questions in perimenopause and menopause, blood is the best starting point; DUTCH has narrower uses.

The short version

Question	Best test
Am I in perimenopause or menopause?	Usually no test; symptoms and period pattern. If needed, blood FSH and estradiol
Is my thyroid, iron or vitamin D the problem?	Blood
Is my hormone therapy dose right?	Symptoms first; blood estradiol when a level is needed
What is my cortisol doing across the day?	DUTCH (or a four-point saliva cortisol)
How am I metabolising estrogen?	DUTCH
Did I ovulate this cycle?	Blood progesterone about a week before the period
What do my hormones do across a whole erratic cycle?	DUTCH Cycle Mapping
Is my testosterone low, and is my testosterone treatment at a safe level?	Blood

Blood (serum)

What it measures. The concentration of the hormone in your bloodstream at the moment of the draw: estradiol, FSH, LH, progesterone, total and free testosterone, SHBG, DHEA-S, TSH and free T4, prolactin, morning cortisol, and the general labs (blood count, ferritin, D, B12, glucose) that matter as much at midlife.

Why it’s the standard. Every guideline, reference range and dosing recommendation in menopause medicine is built on serum measurements. When a clinician needs to know whether your patch is delivering enough estradiol, whether your testosterone is within the female range, or whether your fatigue is thyroid, blood is the only measurement that maps onto the evidence.

Limits. It’s a snapshot. Hormones that cycle over the day (cortisol) or the month (estrogen, progesterone in a cycling woman) can be caught at a misleading moment, which is why timing matters and why a single FSH doesn’t diagnose perimenopause. Our hormone testing guide covers when to draw what.

Finger-prick kits. Home blood-spot kits from accredited labs measure the same hormones and agree well with venous blood when the sample is collected properly. The weakness is everything around the number: cycle timing and interpretation.

DUTCH (dried urine)

What it measures. Hormone metabolites, the processed forms your kidneys excrete, from four or five dried-urine samples across a day: estrogens and the pathways used to break them down, progesterone metabolites, androgens and their pathways, free cortisol and cortisone at each time point plus total metabolised cortisol, and a set of organic-acid markers. Our DUTCH explainer lists them and how to read the results goes section by section.

Where DUTCH adds information.

• Patterns over a day. Because samples are spread from waking to bedtime, the cortisol curve is visible in a way one blood draw can’t show.
• Metabolism. Blood tells you how much estrogen; urine tells you which pathways your body used to break it down and how well the next step worked. Whether that changes treatment is debated, but blood can’t show it at all.
• Erratic cycles. With cycle mapping, DUTCH can chart a whole cycle when you can’t predict the right day for a blood test.

Limits of DUTCH.

• Your current level. Metabolites over hours aren’t the same as circulating hormone now.
• On hormone therapy. Estradiol through the skin or vagina barely shows in urine, so DUTCH underestimates it; oral progesterone floods the progesterone metabolites. Dose decisions on treatment need blood.
• Guidelines. The major menopause and endocrine societies don’t recommend urine testing to diagnose menopause or guide hormone therapy, because it hasn’t been shown to improve outcomes over symptoms and blood. Many integrative clinicians use it for the narrower questions above.
• Cost and volume. It’s more expensive than a blood panel, and the report’s length encourages treating numbers.

Saliva

What it measures. The free, unbound fraction of a hormone in saliva at the moment of collection.

Where it’s reasonable. A four-point salivary cortisol across the day is an accepted way to look at the cortisol rhythm, and late-night salivary cortisol is a standard screening test for Cushing’s syndrome.

Where it isn’t. Estrogen and progesterone in saliva correlate poorly with blood levels and with symptoms, the amounts are tiny and easily disturbed, and any hormone cream used on the hands or face contaminates the sample dramatically. The Menopause Society specifically advises against salivary testing for diagnosing menopause or adjusting hormone therapy. If a clinic’s plan depends on a saliva estrogen or progesterone result, ask why.

Side by side

	Blood	DUTCH (dried urine)	Saliva
Measures	Circulating hormone now	Metabolites over hours	Free hormone now
Collection	Venous draw or finger-prick	4–5 dried samples over a day, by post	Spit tubes, by post
Best for	Diagnosis, thyroid/iron, HT monitoring, testosterone	Cortisol rhythm, estrogen metabolism, erratic cycles	Cortisol rhythm, Cushing’s screening
On transdermal estrogen	Accurate	Underestimates	Contaminated, unreliable
On oral progesterone	Accurate	Inflated metabolites	Poor
Guideline standing for menopause care	Standard	Not recommended for diagnosis or dosing	Advised against
Typical cost	Lowest	Higher	Moderate

What happens after the results

Whatever a DUTCH report shows, it leads to a treatment conversation:

• Erratic estrogen with low progesterone in perimenopause opens the question of cyclic progesterone or hormone therapy for mood, sleep and bleeding.
• Low estrogen after menopause with symptoms is the ordinary case for hormone therapy, decided on how you feel, with blood levels as the check once you’re on it.
• A flattened or late-peaking cortisol curve points to the sleep and stress work on our fatigue and sleep pages, and sometimes to treating the night sweats that are driving it.
• Androgen pathway findings inform the options for hair thinning and low libido.

The test informs the conversation, which starts with a $99 video visit, with pricing published. Already have a DUTCH report? Bring it to your first visit and a clinician will go through it with you.

What we recommend

Start with no test if the picture is clear. Over 45 with changing periods and typical symptoms, perimenopause is a clinical diagnosis and treatment is decided on symptoms. When testing helps, start with blood because it catches thyroid, iron and other midlife look-alikes and is used to monitor hormone therapy. Add DUTCH for a specific question it can answer, such as a cortisol pattern behind “wired but tired”, an estrogen-metabolism concern or cycles too erratic to time. Skip saliva for sex hormones.

Golden Leaf Health orders blood panels when they’ll change a plan, can order and interpret DUTCH for the narrower questions above, and doesn’t sell the DUTCH kit online. Whatever you’ve already had done, bring it; results from another practice are usable. Book a first visit if you’d like help deciding what, if anything, to test.
