Episode 11: DUTCH: A Novel (and useful!) Urinary Hormone Test with Mark Newman

As a clinician measuring urine, serum and salivary hormone levels
in my patients routinely, I’ve always got questions around which
testing method is the best. Thus, I was excited to chat with Mark
Newman and pick his brain on all things hormone testing. As he
says, “I’m an inch wide and a mile deep. I’ve spent pretty much my
whole career in measuring reproductive and adrenal hormones.” It’s
true. As you’ll hear, Mark is a font of knowledge in this arena. In
this interview, Mark covers the various specimen type and their
respective utility and limitations, we then dive into a discussion
around the unique characteristics of the DUTCH test….In brief,
DUTCH is an easy 4 specimen urine test, collected over the course
of a day, covering the bases of sex and adrenal hormones, plus
metabolites (including 2-Methoxyestrone) and melatonin. It’s
reflective of 24-hour output, but diurnal variation is captured as
well-- thus great for cortisol.
