Our Commitment to Provide Top-Tier Testing

The DUTCH Test® (Dried Urine Test for Comprehensive Hormones) helps practitioners answer complex clinical questions by providing the most comprehensive hormone monitoring results with simple patient collection. Our rigorous pursuit for the truth in hormone testing has produced multiple peer-reviewed studies proving the effectiveness of dried urine testing as an alternative to serum (blood) or saliva for monitoring a variety of hormone therapy applications. We use the most accurate method available (LC-MS/MS) and our tests are used by thousands of healthcare providers and their patients all over the world.

At DUTCH, we are committed to providing you with an evidence-based approach to integrative care. We know that questions exist in the integrative medicine community about the best way to provide hormones to patients as well as the best way to monitor dosing. This study, peer-reviewed by the rigorous team at Menopause, highlights the accuracy of urine metabolite testing for monitoring of estrogen replacement therapies.

  • The first peer-reviewed study to compare FDA approved patches and gels to compounded estrogen creams, a key therapeutic choice for many providers in the integrative medicine community.
  • Estrogen exposure from compounded transdermal E2 creams increases in a dose-dependent manner; however, the amount of estrogen exposure associated with compounded creams is significantly lower than estrogen exposure associated with FDA-approved transdermal E2 patches and gels.
