Mark Newman is the founder Precision Analytical and the developer of the DUTCH test, one of the most accurate and patient-friendly measures of sex hormones on the market. The test eliminates the need for multiple types of testing by using dried urine to measure sex hormones, hormone metabolites, and free cortisol. Free cortisol is a key indicator of the health of the HPA axis — and having that measure, alongside a measure of sex hormones and their metabolites, gives providers more information so they can achieve better clinical outcomes. The test can be especially valuable in complex cases. Now, Mark has developed DUTCH Plus with Cortisol Awakening Response and he talks with Dr. Fitzgerald about the new test, testing best practices, and the most cost effective tests for patients.
