DUTCH Test: What to Expect
What it measures
The DUTCH test (Dried Urine Test for Comprehensive Hormones) measures sex hormones like estrogen, progesterone metabolites, and testosterone, plus cortisol and cortisol metabolites — showing not just hormone levels but how your body is processing them. That metabolite view is why many practitioners choose it over a single blood draw.
How collection typically works
Collection happens across one day at set points — commonly around dinner time, bedtime, overnight if you wake, and upon waking, with the exact schedule printed on your kit's collection cards. For each sample, you saturate a filter-paper card with urine and leave it to dry openly, usually for 24 hours, before packaging. Many kits advise moderating fluid intake in the hours before and during collection so samples aren't diluted — your kit's card will state its specific guidance.
Timing and preparation
For women who are cycling, practitioners commonly schedule collection in the luteal phase — often around a week after ovulation — so progesterone is measurable; confirm your target day with whoever ordered the test. Some supplements and medications can influence results, so your practitioner may advise on what to pause and when. Note your collection times accurately on the cards — the daily pattern is a large part of what the test reads.

Frequently asked questions
- How many samples does the DUTCH test take?
- Typically four to five dried-urine samples collected at set points across one day and the following morning, per the schedule on your kit's collection cards.
- What day of my cycle should I take the DUTCH test?
- For cycling women, collection is commonly scheduled in the luteal phase — your practitioner will confirm the exact day based on your cycle.
- Can I drink water during DUTCH collection?
- Kits generally allow normal moderate hydration but advise against large fluid intake that could dilute samples. Follow the specific guidance printed on your kit.
