About the Lab

Precision Analytical (DUTCH) conducts advanced hormone testing using an innovative method that analyzes dried urine specimens.

Dried Urine Test for Comprehensive Hormones (DUTCH) was developed to provide the most comprehensive and reliable information on hormones without compromising accuracy in results.

The DUTCH test, an acronym for Dried Urine Test for Comprehensive Hormones, has become a cornerstone in understanding complex hormonal landscapes, offering invaluable insights into patient health.

About Precision Analytical (DUTCH)

Precision Analytical began in 2012 and is headquartered in McMinnville, Oregon. They ensure testing methods' accuracy, precision, and reproducibility by fulfilling certification requirements and internal laboratory criteria.

Precision Analytical is a distinguished laboratory known for its development and implementation of the DUTCH test that utilizes dried urine samples for comprehensive hormonal analysis.

Development of the DUTCH Test

The Dried Urine Test for Comprehensive Hormones (DUTCH) was developed by the founder and president of Precision Analytical, who was motivated by the desire to overcome the limitations of existing hormone tests.

Traditional methods often required multiple types of samples and could not provide the comprehensive data that clinicians needed to treat complex hormonal imbalances effectively. 

The DUTCH test was designed as an alternative, capable of extracting extensive hormone data from a single dried urine sample.

What is a DUTCH Test?

DUTCH stands for Dried Urine Test for Comprehensive Hormones, and specializes in the assessment of hormone health. 

The Methodology Behind the DUTCH Test

The DUTCH test accomplishes hormone testing by analyzing dried urine samples. This method is specifically designed to capture and measure a wide range of hormonal metabolites from a single dried urine specimen. 

The innovative collection technique is both convenient and also effective in stabilizing the hormones until analysis, which can be crucial for accurate results. This method provides a comprehensive view of a patient’s hormonal balance over a complete 24-hour period, providing insights into the diurnal patterns of hormone release.

Comprehensive Hormone Analysis

Unlike traditional blood serum tests, the DUTCH test measures a broad spectrum of hormones and their metabolites including cortisol and melatonin alongside sex hormones like estrogen and testosterone. 

This analysis helps in diagnosing complex conditions related to hormone imbalances such as adrenal disorders, menstrual irregularities, and sleep disturbances.

By providing detailed information on hormone production and metabolism, the DUTCH test offers a deeper understanding of various body functions, enabling more targeted and effective treatment strategies.

Benefits of the DUTCH Test

The test is minimally invasive and can be conducted in the comfort of their own home, making it significantly easier than blood draws which often require visits to a clinic. 

For healthcare providers, the DUTCH test offers detailed insights into the hormonal milieu of their patients, aiding in crafting personalized treatment plans.

Popular Tests Offered by Precision Analytical

Precision Analytical offers a variety of advanced diagnostic tests through its DUTCH (Dried Urine Test for Comprehensive Hormones) product line, each designed to provide specific insights into hormonal health. These tests are tailored to meet diverse needs, ranging from comprehensive hormonal assessments to focused analyses of adrenal or sex hormones. This section will explore the most popular tests provided by Precision Analytical, highlighting their purposes and unique features.

DUTCH Complete™

The DUTCH Complete™ is one of the most comprehensive tests available, assessing sex and adrenal hormones along with their metabolites. It also includes the daily free cortisol pattern, organic acids, melatonin, and 8-OHdG. This test is ideal for a broad hormonal overview to diagnose various conditions, from stress response to sleep disorders. The requirement for a written prescription in certain states underscores the regulatory compliance and professional standards maintained by Precision Analytical.


Expanding on the capabilities of the DUTCH Complete™, the DUTCH Plus™ incorporates both urine and saliva samples to measure the Cortisol Awakening Response (CAR), alongside the standard sex and adrenal hormone assessments. This test is particularly valuable for understanding the body’s response to stress upon waking, which can be crucial for patients dealing with anxiety, depression, or chronic stress conditions.

DUTCH Sex Hormone Metabolites

This test focuses specifically on estrogen, progesterone, and androgen hormones and their metabolites. It is an excellent tool for obtaining a baseline reading of these hormones or for monitoring hormone replacement therapy. This targeted approach allows for precise adjustments in hormone therapy, enhancing treatment efficacy and safety.

DUTCH Adrenal

The DUTCH Adrenal test provides an analysis of free cortisol patterns that are comparable to saliva testing but with the added benefit of measuring cortisol metabolites. This provides a more complete picture of adrenal health and can be especially helpful in diagnosing adrenal fatigue or dysfunction.

DUTCH Cortisol Awakening Response (CAR)

Offered exclusively through saliva samples, the DUTCH CAR test measures the cortisol awakening response, daily patterns of free cortisol, and includes an insomnia cortisol sample. This test is particularly useful for patients experiencing sleep-related issues or abnormal stress responses.

DUTCH Cycle Mapping and Bundles

For a detailed hormonal analysis throughout the menstrual cycle, Precision Analytical offers the DUTCH Cycle Mapping™ and various bundle options like Cycle Mapping + Complete or Cycle Mapping + Adrenal. These tests are invaluable for investigating menstrual irregularities, fertility issues, or cyclical mood disorders. By combining different tests, these bundles provide a comprehensive overview of hormonal fluctuations throughout the cycle.

Add-On Extra Cortisol Marker

This add-on allows for the measurement of cortisol at additional time points, which can be critical for diagnosing and managing conditions like Cushing's syndrome or adrenal insufficiency. This flexibility in testing is part of Precision Analytical's commitment to tailored healthcare solutions.


The DUTCH OATs test includes measurements of neurotransmitter metabolites, nutritional organic acids, 8-OHdG, and melatonin, offering insights into nutritional deficiencies, hormone imbalances, and oxidative stress. 

This test is particularly suited for a holistic view of a patient's health status, linking hormonal activity with broader physiological processes.
