Urine testing is also not a good way to measure thyroid hormones. Also, if your kidneys are not functioning well, then you are not excreting urine as well as you should and this can impact urine testing. Also, saliva has some advantages for the cortisol awakening response (CAR)... 8:50  Estrogen metabolism.  Urine testing allows for monitoring of estrogen metabolites that you can't get with serum testing and this can give us some information about how the person processes their hormones and also provides some information about estrogen related cancer risk....                              Mark Newman, MS is a recognized expert and international speaker in the field of hormone testing. Mark spent nearly 25 years developing and directing urine, blood, and saliva-based hormone testing along with other biomarkers like organic acids. His unique experience led him to pursue a revolutionary way to test hormones; so Mark began his own lab, Precision Analytical Inc., to create the latest innovation in hormone testing, the DUTCH Test® (a Dried Urine Test for Comprehensive Hormones). In pursuit of the most accurate, evidence-based testing and best practices, Mark has co-written multiple peer-reviewed research papers and abstracts, highlighting the accuracy and clinical utility of dried urine hormone testing. Mark’s primary educational goal is to find and communicate truths about HRT monitoring to help providers care for their patients. He understands that each form of testing has its own strengths and weaknesses, which is why he encourages clinicians to follow the evidence even when lab testing isn't clinically helpful. For clinicians to learn more about the DUTCH test, go to DUTCHtest.com.  Patients can find a referral to a DUTCH Lab provider to order and interpret the testing for them. Dr. Ben Weitz is available for Functional Nutrition consultations specializing in Functional Gastrointestinal Disorders like IBS/SIBO and Reflux and also Cardiometabolic Risk Factors like elevated lipids, high blood sugar, and high blood pressure.  Dr. Weitz has also successfully helped many patients with managing their weight and improving their athletic performance, as well as sports chiropractic work by calling his Santa Monica office 310-395-3111. Dr. Weitz is also available for video or phone consultations and he uses DUTCH testing regularly.
