Precision Analytical Inc. Announces Unprecedented Peer-Reviewed Publication for 25 Hormone, Organic Acid, & Melatonin Metabolites in Dried Urine


McMinnville, OR — (March 18, 2021)

Today, Precision Analytical Inc., creators of the DUTCH Test® (Dried Urine Test for Comprehensive Hormones), announced the publication of their latest study, Reliability of A Dried Urine Test for Comprehensive Assessment of Urine Hormones and Metabolites, demonstrating their dried urine profile for reproductive hormones and their metabolites, an array of organic acid, and melatonin metabolite results correlate with liquid and traditional 24-hour urine (the current gold standard).

Mark Newman, MS, Founder and President of Precision Analytical said, “These 25 hormone, organic acid, and melatonin metabolites now have their validation data in mainstream publications. With our previous research for progesterone, estradiol, and cortisol and its metabolites, we are close to having the entire Dutch Test panel’s data validated against gold-standard methodology in peer-reviewed literature. Precision Analytical continues to set the bar as the functional leader for dried urine technology for hormone testing.”

This new study also demonstrated that measurements of reproductive hormones in a collection of four dried-urine samples over a 15-hour span throughout the day would accurately reflect the measurement of these hormones in a 24-hour urine collection. The DUTCH Test 4-spot dried collection method can be collected at home and is overwhelmingly preferred by patients over a traditional 24-hour urine collection or even serum (blood) tests. For providers, DUTCH is a useful clinical testing tool for hormone dysregulation and is becoming a desired method for determining hormone health. Precision’s research has continued to expand the DUTCH model of testing to include a comprehensive overview of male, female, and stress-related hormones along with markers for related vitamin deficiencies and neurotransmitter balance.
