Precision Analytical was started by Mark Newman with the help of some very talented physicians and analytical chemists. Mark’s several years experience working with hormone testing labs provided him a vision to create a revolutionary way to test hormones.

The question of how to best test hormones drove the creative process to initiate Precision Analytical Labs. The previous hormone testing methods via Blood (serum), urine and saliva had significant limitations. Precision Analytical’s unique DUTCH (Dried Urine Testing for Comprehensive Hormones) test bridges the gap between existing methods to create better tools for healthcare providers to address the needs of their patients. The fact that their DUTCH test is now used by leading Functional Medicine Practitioners globally is great validation for the work put in by Mark and his team to make this test available.


“DUTCH is the most advanced test available for sex and especially adrenal hormones!”
 DR. JOSEPH MERCOLA, DO,  New York Times best selling author



“I have spent my entire career developing hundreds of novel lab tests. After developing 24hr urine, saliva, bloodspot, and serum tests, I developed DUTCH. I have found it to be the most comprehensive and reliable hormone testing model. Watch some of our videos and see for yourself!”


Mark believes that since they were the pioneers with this technology and their sole business focus is DUTCH testing, that their lab will continue to remain at the cutting-edge of bringing validated markers and increasing the utility of this test amongst practitioners.

RN Labs is proud to represent this test in Australia and bring continuing education by way of seminars and webinars to train practitioners on this invaluable test for hormone testing.
