“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 Newman

Who We Are

Precision Analytical was started by Mark Newman with the help of some very talented physicians and analytical chemists. Mark spent years directing a urine hormone testing lab and most recently directed salivary hormone testing at ZRT laboratories for over six years gaining a fairly unique and thorough perspective on blood, urine, and saliva hormone testing. This unique experience led to a vision for a revolutionary way to test hormones. The question of how to best test hormones is what drove the creative process that initiated this lab. Blood (serum), urine, and salivary testing all have significant limitations. Our unique testing methods bridge the gap between existing methods to create better tools for healthcare providers to address the needs of their patients.

Precision Analytical exists to make it easier for patients and their healthcare providers to find answers to complex clinical questions that affect their lives every day. Our unique hormone testing and reporting methods create better tools for healthcare providers to explore hormone issues with their patients. We are fully committed to the mission of improving the lives of those who trust us for their laboratory testing needs.

Precision Analytical is a CLIA certified laboratory run by a small team of dedicated scientists with combined experience of over 50 years in performing laboratory tests and developing novel testing methods. Lab testing involves a series of questions that must be addressed in putting together methods that are accurate and precise (reproducible). Lab quality is critical to ensuring that healthcare providers make the best decisions they can for their patients.

Another issue that can hamper the clinical decision making process is the complexity of hormone testing results. We are committed to creating lab reports that help increase the confidence and competence of healthcare providers as they steer their patients towards a healthier life.

Book Quote

“After working with all three of these test [blood, saliva, and urine] for many years, my favorite — and the one I consider the most reliable at the moment — is serial urine.”
