Podcast Highlights

1:48  Dried urine testing or DUTCH testing uses a dried sample for convenience, which is a big advantage over the other leading type of urine hormone testing, which is the 24 hour urine test that requires carrying around a jug of urine that you keep in the refrigerator all day.  This is very inconvenient and you lose the the changes in those hormones levels, esp. cortisol, that vary throughout the day using a 24 hour sample.  The dried urine test you collect samples throughout the day so you can look at the cortisol pattern, which correlates with what is seen on saliva in studies that have been published.  And the urine testing of hormones allows you to see the metabolites of estrogens and androgens that you can't see on blood testing.... 

4:57  On the other hand, dried urine testing does not allow you to measure SHBG, which can be measured through blood, such as when a woman is on birth control and this drives up her SHBG, which drives down her free hormones. 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.
