Precision Analytical are the global leaders in dried urinary testing for comprehensive hormones and popularised the term  “DUTCH” test. The DUTCH Complete™, DUTCH Plus®, and DUTCH Cycle Mapping™ tests are available in Australia exclusively from RN Labs – look for the trademark to make sure you are prescribing the genuine, research-backed Precision Analytical DUTCH tests for your patients.

The Origin of DUTCH Testing

Precision Analytical was started by Mark Newman with the help of some very talented physicians and analytical chemists. Mark spent years directing a urine hormone testing lab, gaining a fairly unique and thorough perspective on blood, urine, and saliva hormone testing. This unique experience led to a vision for a revolutionary way to test hormones.

The question of how to best test hormones is what drove the creative process that initiated this lab. Their unique testing methods that have created the DUTCHTM Test bridge the gap between existing methods to create better tools for healthcare providers to address the needs of their patients.

Precision Analytical are fully committed to the mission of improving the lives of those who trust us for their laboratory testing needs. They are CLIA licenced and fully transparent with their testing methods.

Dutch Plus®

  • Takes hormone testing to a whole new level: Dutch Complete™ + Cortisol Awakening Response (CAR)
  • Includes Metabolites of Oestrogens, Androgens, Progesterone, Cortisol, Melatonin, Adrenaline, Noradrenaline and 8-OHdG as well as Organic Acid makers for neurotransmitters and nutrient metabolism.
  • The diurnal pattern of Free Cortisol and Cortisone are also provided, including the Cortisol Awakening Response.
  • An optional nighttime Insomnia Cortisol measurement is also available.

The DUTCH Plus® includes everything in the DUTCH Complete™ test, PLUS the Cortisol Awakening Response (CAR).

The DUTCH Plus® uses four dried urine samples and five saliva samples. These samples are collected over the course of one day, from waking to bedtime.

The DUTCH Plus® report includes:

Metabolites of Oestrogens (11, including E1, E2, E3, 2-OH-E1, 4-OH-E1, 16-OH-E1, 2-methoxy-E1), Androgens (8, including Testosterone, DHT and DHEA-S), Progesterone (2), Cortisol (3), and Melatonin, 8-OHdG, Neurotransmitter Metabolites (2, HVA, VMA) and Nutritional Organic Acids (4, MMA, Xanthurenate, Kynurenate, Pyroglutamate).

The diurnal pattern of Free Cortisol and Cortisone are also provided, including the Cortisol Awakening Response and an optional nighttime Insomnia Cortisol measurement.

Even though a patient may have “normal” free cortisol levels throughout the day, that doesn’t always mean everything is functioning properly. The graph below shows two good examples. A blunted or exaggerated CAR can appear, even when single samples return “normal” results. The HPA axis might not be appropriately responding when faced with a stressor, even when cortisol levels are fluctuating nicely throughout the day. The “stress” of waking, allows us to test the HPA axis in a way that has been independently correlated to clinical outcomes and cannot be assessed by other cortisol tests on the market.

Dutch Cycle Mapping™

  • Maps Hormones Through a Full Menstrual Cycle
  • Provides a Comprehensive View of Key Hormone Fluctuations Throughout an Entire Cycle
  • More Accurate than Saliva for Progesterone and Especially for Estradiol

This test is not for everyone. It is intended for any particularly challenging premenopausal patients.

It is most useful in cases of:

  • Infertility
  • Patients with functional ovaries, but who have had their uterus removed (no bleeding)
  • Patients with uterine ablations (cycling, but not bleeding)
  • Patients with highly irregular cycles (making it hard to test them well in one day)
  • Patients with intermittent symptoms that seems to ‘cycle’ with their hormones

This test is not Intended for:

  • Postmenopausal women
  • Women on birth control (suppresses ovulation and produces clinically irrelevant data on a cycle mapping test)
  • Provides a uniquely comprehensive view of key female hormone fluctuations/balance throughout an entire cycle
  • More accurate than saliva for progesterone and especially for estradiol
  • Easier and more extensive collections for improved characterisation of hormone peaks over time
  • The most accurate methods available are used for each test. These methods show increased accuracy over the standard immunoassays used in typical serum and saliva testing
  • All Precision Analytical testing methods go through a rigorous and ongoing validation process to verify accuracy, precision, recovery, linearity, etc. in the pursuit of the most accurate and precise techniques available for hormone testing
