DUTCH Testing

What is a DUTCH Test?

The DUTCH test is a dry urine test for hormones. All 3 estrogens, progesterone, testosterone, DHEA, cortisol, and their metabolites.

Why use DUTCH testing?

The Easiest Patient Collection:

Patients collect just four or five dried urine samples over a 24-hour period. Dried samples are stable for several weeks making them convenient to ship worldwide.

Analytical and Clinical Validation:

Precision Analytical’s testing methods go through a rigorous validation process to verify accuracy, recovery, and linearity. We pride ourselves in relentlessly pursuing the most accurate and precise techniques available for testing. See the data on the next page to support the analytical and clinical validation of this powerful new testing model.

Effective HRT Monitoring:

DUTCH testing was designed to be optimally effective for most forms of hormone replacement therapy. Unique methods are used for improved monitoring of oral progesterone and vaginal hormones. 

What are the symptoms of needing a DUTCH test?
  • Changing body
  • Night sweats and hot flashes
  • Fogginess
  • Fatigue
  • Changing menstruation patterns
  • Vaginal dryness
  • Erectyle disfunctions
  • Weight gain/ muscle loss
  • Abdominal weight gain
  • Low energy
  • Moodiness and MORE “not feeling like myself”

Why DUTCH VS. other methods?

DUTCH vs. Saliva Testing – While the free cortisol pattern in saliva has clinical value, there is a significant missing piece to surveying a patient’s HPA-Axis function with saliva testing – measuring cortisol metabolites. To properly characterizea patient’s cortisol status, free and metabolized cortisol should be measured to avoid misleading results when cortisol clearance is abnormally high or low. Likewise with sex hormones, measuring estrogen and androgen metabolites gives a fuller picture for more precise clinical diagnosis of hormonal imbalances and HRT monitoring.

DUTCH vs. Serum Testing – While the most universally accepted testing method (due to the availability of FDA- cleared analyzers that are reliable and inexpensive), serum testing is lacking in some areas. Adrenal hormones cannot be effectively tested in serum because free cortisol cannot be tested throughout the day. There is also a lack of extensive metabolite testing (especially for cortisol and estrogens).

DUTCH vs. 24-Hour Urine Testing – There are two primary drawbacks to 24-hour urine testing of hormones. First, the collection is cumbersome, and as many as 40% of those who collect, do so in error (Tanaka, 2002). Secondly, dysfunction in the diurnal pattern of cortisol cannot be ascertained from a 24-hour collection. Some providers add saliva for daily free cortisol. DUTCH eliminates the need for two tests. 

How do we administer the DUTCH Test?

The DUTCH test can be purchased directly from Immunity and taken home OR we can have the test mailed to client. Either option, payment is collected prior to handing out or mailing. Provider will inform client how to do the test and there are instructions inside the test kit. 

How to receive your results?

Results typically take 3 – 5 weeks to come back. The day client puts the test kit in the mail, they will need to call Immunity to schedule their follow up appointment.
