How Does the Dutch Test Compare to Other Hormone tests?
DUTCH vs. Saliva Testing
While the free cortisol pattern in saliva has clinical value, there is a significant missing piece to surveying 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 full-range picture for a more precise clinical diagnosis of hormonal imbalances and HRT monitoring, allowing for the best care services for you. A women’s health specialist can help administer this test.
DUTCH vs. Serum Testing
While the most universally accepted testing method (due to the availability of FDA-cleared analyzers that are reliable and inexpensive), serum testing 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.
