Precision Analytical offers a revolutionary new model of hormone testing called DUTCH - a Dried Urine Test for Comprehensive Hormones. By using 4 simple, dried urine collections, DUTCH takes the advantages of a 24-hr urine test and adds the pattern of free cortisol (which has traditionally been acquired from saliva). Free cortisol concentrations accurately replace its testing in saliva. Sex hormone analysis uses the most accurate method available (GC-MS/MS) and offers basic hormones and extensive metabolites (2-OH, 4-OH, 16-OH, methoxyestrogen, DHT). Adrenal hormone testing is the most comprehensive available. This test includes free cortisol and also a better marker of total cortisol production by including cortisol metabolites. Melatonin is also tested. Lastly, DUTCH testing is built to optimize HRT monitoring. Special methods (separation of free and conjugated hormones) and additional metabolites make the testing unparalleled for testing with and without HRT.
