Precision Analytical

Precision Analytical Consulting and Laboratory was started by Mark Newman with the goal of developing an improved model for testing patient’s sex and adrenal hormones.  Mark’s career path had uniquely prepared him to be up to the task.  After helping to develop 24-hour urine testing at one lab, Mark had the opportunity to develop some novel urine tests using dried samples at yet a second laboratory.  Lastly, he had the privilege of directing the laboratory testing services of ZRT Laboratory as Vice President of Lab Operations for more than six years.

Having directed the development of blood, urine and saliva testing for hormones, Mark had a great perspective on the pros and cons of each method.  He then set out to develop a new model of testing to improve the clinical utility and improve the patient experience with one laboratory test.  DUTCH (Dried Urine Testing for Comprehensive Hormones) was the result of this extraordinary endeavor.  Developing a new model of testing that is more reliable for providers was just part of the mission of developing this test.  Mark also developed most of the different hormone tests in the DUTCH profile by all of the available methods (immunoassay/ELISA, colorimetric, GC-MS, LC-MS, LC-MS/MS, GC-MS/MS) and chose the very best method for each test.
