Precision Analytical and the DUTCH Test: Company
Overview and Testing Focus
Company Background
Precision Analytical, founded by hormone testing expert Mark
Newman, developed the DUTCH Test® (Dried Urine Test for
Comprehensive Hormones) to transform the field of functional
hormone assessment.
Unlike traditional blood or saliva tests, which provide limited
snapshots, Precision Analytical sought to create a more complete,
dynamic view of hormone production, metabolism, and
rhythmicity [1].
Since its launch, the DUTCH Test has been recognized by
integrative and functional medicine practitioners worldwide as a
gold standard for hormonal evaluation, adrenal assessment, and
circadian rhythm analysis.
The DUTCH Test: What It Measures
The DUTCH Complete™ panel measures over 35 different markers
in a dried urine sample:
● Adrenal hormones and metabolites (cortisol, cortisone, DHEA)
● Sex hormones and metabolites (estrogens, progesterone,
testosterone, androgens)
● Cortisol Awakening Response (CAR) (salivary cortisol
dynamics immediately upon waking)
● Melatonin production and metabolism
