This advanced hormone testing was developed to improve on available hormone testing options. The DUTCHTM Complete offers the most extensive profile of sex and adrenal hormones along with their metabolites.
Additionally, the daily (diurnal) pattern of free cortisol is included along with melatonin (60HMS) and 8-OHdG (an oxidative stress marker). This unique combination of clinical information is not available by any other method.
WHY USE DUTCHTM
The Easiest Patient Collection
Patients collect just four or five dried urine samples over a 24-hour period. Dried samples remain stable for several weeks and are the most convenient, and cost effective, for domestic and international shipping.
Analytical and Clinical Validation
Precision Analytical's testing methods go through a rigorous validation process to verify accuracy, recovery, and linearity. We pride ourselves in relentlessly pursuing the most accurate and precise techniques available for testing. See the data on the back to support the analytical and clinical validation of this powerful new testing model.
Effective HRT Monitoring
DUTCHTM testing was designed to be optimally effective for most forms of hormone replacement therapy. Unique methods are used for improved monitoring of oral progesterone and vaginal hormones.
HOW DOES THE DUTCHTM COMPLETE COMPARE TO OTHER HORMONE TESTS?
DUTCHTM vs Saliva Testing - While the free cortisol pattern in saliva has clinical value, there is a significant missing piece to ? A patient's HPA-axis function with saliva testing - measuring cortisol metabolites. To properly characterize a patient's cortisol status, free and metabolized cortisol should be measured to avoid misleading results when cortisol clearance is abnormally high or low. Likewise with sex hormones, measuring estrogen and androgen metabolites gives a fuller picture for more precise clinical diagnosis of hormonal imbalances and HRT monitoring.
DUTCHTM vs Serum Testing - While serum is the most universally accepted testing method (due to the availability of FDA-cleared analyzers that are reliable and inexpensive), it is lacking in some areas. Adrenal hormones cannot be effectively tested in serum because free cortisol cannot be tested throughout the day. There is also a lack of extensive metabolite testing (especially for cortisol and estrogens).
DUTCHTM vs 24-hour Urine Testing - There are two primary drawbacks to urine testing of hormones. First, the collection is cumbersome, and as many as 40% of those who collect, do so in error (Tanaka, 2002). Secondly, dysfunction in the diurnal pattern of cortisol cannot be ascertained from a 24-hour collection. Some providers add saliva for daily free cortisol. DUTCHTM eliminates the need for two tests.
