This advanced hormone testing was developed to surpass industry standards for available testing options. DUTCH testing offers the most extensive profile of sex and adrenal steroid hormones, along with their all-important metabolites.
The daily (diurnal) pattern of free cortisol, along with melatonin is included. This unique combination of clinical information is not available by any other testing method.
Effective HRT Monitoring
DUTCH testing was specifically made to be optimally effective for most forms of hormone replacement therapy. Unique methods are used for improved monitoring of oral progesterone and vaginal hormones.
The Easiest Patient Collection
Patients collect just four or five dried urine samples over a 24-hour period. Dried specimen samples are convenient to collect, easy to ship and stable for several weeks.
Analytical and Clinical Validation:
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.
Validating the Concept
Is Measuring Diurnal Cortisol Intervals in Urine Similar to Saliva?
Do Multiple Dried Urine Sample Values Compare with Full 24-hour Urine Collections?
Most Accurate Methods Used for Hormone Testing
Cortisol, cortisone and related metabolites are tested by LC-MS/MS. The remaining hormones are tested by GC-MS/MS. 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.
