PEER-REVIEWED RESEARCH

Scientific literature has much to say about the viability of measuring hormones in urine. In a newly released publication in the peer-reviewed journal, BMC Chemistry, a new study 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.

A journal published in 2020 featured DUTCH in a study to determine the utility of dried urine sampling in obtaining measures of cortisol and cortisol metabolites. Additional aims were to evaluate if a 4-spot urine collection is representative of a 24-hour urine collection and if expected diurnal cortisol patterns can be observed in samples from both urine and saliva.

DUTCH’s first peer-reviewed journal submission was published in 2019 in BMC Chemistry. It was completed collaboratively with the University of Southern California Reproductive Endocrine Clinical Laboratory and shows that analysis of urine samples dried on filter paper provides results correlating with serum (blood) results. The research also shows a collection of four samples during the day (4-spot method) can be substituted for a 24-hour collection and the analysis of urine from dried samples is equivalent and is as adequately stable as liquid urine samples.

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.

More peer-reviewed journal submissions featuring DUTCH are in process.

RESEARCH COLLABORATIONS AND CLINICAL TRIALS

DUTCH testing was recently used in tandem with the Oura Ring to explore a potentially new method for predicting and defining the fertile window for women. This study was completed collaboratively with researchers from The Helen Wills Neuroscience Institute, University of California Berkley. Mark Newman, MS, president and founder of Precision Analytical Inc. was a coauthor of this paper which demonstrates how ultradian rhythms of distal body temperature and heart rate variation, measured using the Oura Ring, were able to anticipate the LH surge “at least two days prior to its onset in 100% of individuals.” This finding has the potential to lead to the full development of a novel fertility awareness tool that would be extremely useful for both women trying to conceive, as well as those seeking a natural contraception method.

DUTCH-BASED RESEARCH

It is important to remember that many of the concepts used in the DUTCH test® are already established in the literature. The relevance, for example, of measuring estrogen metabolites in spot urine samples is found both in the scientific literature and is offered by other labs. For this test, we are simply using dried samples, which show excellent correlation to liquid urine and great stability for months at room temperature. One challenge to serum hormone testing is the fact that reproductive hormones change somewhat unpredictably throughout the day. Filicori, Butler and Crowley showed in the Journal of Clinical Investigation that serum progesterone values are highly variable throughout the day in premenopausal women. One advantage of the DUTCH collection and testing methodology is that the four urine samples used represent over half of the day, instead of just one moment in time.

Precision Analytical Inc. maintains a transparent approach to discussing the strengths and challenges of all testing modalities. Some competing labs and even a few healthcare practitioners have circulated questions about the DUTCH Test®. We asked ourselves many of the same questions when we began exploring the DUTCH concept. These papers give an overview of the challenges and questions to using dried, spot-urine samples for hormone analysis, and address some of the questions regarding DUTCH, hormone testing in general, and even hormone replacement therapy:
