DUTCH test vs blood hormones — when each one actually wins.
The DUTCH test (Dried Urine Test for Comprehensive Hormones) shows hormone metabolites; blood pathology shows the active hormones with validated ranges. Here is when each is the right tool — and how Her Form decides.
Short answer: for diagnosing perimenopause, menopause, ovarian reserve, thyroid disease, iron, vitamin D, fertility status and metabolic health — blood wins. The DUTCH test is not validated against those questions, and most international insurers will not reimburse it.
DUTCH genuinely adds value in two narrow cases: mapping estrogen metabolism pathways (2-OH vs 4-OH vs 16-OH) when estrogen-dominance symptoms or family history warrant it, and reading cortisol's diurnal rhythm across the day when adrenal-stress patterns dominate the picture.
When blood is the right tool
- · Perimenopause and menopause — FSH, LH, estradiol against cycle day
- · Fertility & ovarian reserve — AMH, FSH, LH, estradiol, prolactin, thyroid
- · Thyroid disease — TSH, free T3, free T4, TPO antibodies (validated only in blood)
- · PCOS — total/free testosterone, SHBG, LH:FSH ratio, fasting insulin, HbA1c
- · Iron, vitamin D, B12, lipids, glucose — only validated in blood
- · Insurance reimbursement — itemised pathology receipts
When the DUTCH test can add value
- · Symptoms or family history pointing at estrogen-metabolism issues (heavy periods, fibroids, breast tenderness, family history of estrogen-driven cancers)
- · Adrenal-stress / cortisol-rhythm pictures where one morning blood cortisol won't capture the daily curve
- · As a second step after validated bloods have answered the diagnostic question
How Her Form decides
We always start with a validated blood panel shaped around your question — perimenopause, fertility, PCOS, thyroid, full-body. If the result, your symptoms or your family history opens an estrogen-metabolism or cortisol-rhythm question, our health specialists flags it and an optional 1:1 consult with Robyn is available to talk through whether DUTCH is worth adding in your specific case.
Start with the right blood panel
Three places most women start: full female hormone work-up, perimenopause panel, or fertility insights.
What is the DUTCH test?+
DUTCH (Dried Urine Test for Comprehensive Hormones) measures hormones and their downstream metabolites in dried urine collected over a day. It excels at showing how your body processes hormones — particularly estrogen metabolism and cortisol rhythm.
When does blood beat the DUTCH test?+
For most medical questions. Diagnosing perimenopause, menopause, ovarian reserve (AMH), thyroid disease, iron, vitamin D, fertility work-up and metabolic health all rely on validated blood reference ranges. The DUTCH test is not validated for these.
When does the DUTCH test add something blood doesn't?+
Two specific situations: (1) mapping estrogen metabolism (2-OH vs 4-OH vs 16-OH pathways) when you have estrogen-dominance symptoms or family history, and (2) reading cortisol's diurnal pattern across the day when adrenal-stress symptoms dominate.
Should I do both?+
Sometimes. The order we recommend: start with a validated blood panel to answer the diagnostic questions. If estrogen-metabolism or cortisol-rhythm questions remain, add DUTCH as the second step. Don't start with DUTCH for a perimenopause or fertility question.
Is DUTCH covered by insurance?+
Almost never. International insurers reimburse validated blood pathology with itemised receipts; specialty urinary metabolite panels are typically classified as wellness testing and excluded.
How is Her Form's approach different?+
We run validated, accredited-lab blood pathology with cycle-timed draws, women's-hormone-shaped panels and written specialist review. If your picture would genuinely benefit from DUTCH on top, we say so.
