What can the DUTCH Plus®tell us that the DUTCH Complete™ and other adrenal tests cannot? Even
though a patient may have “normal” free cortisol levels throughout the day, that doesn’t always mean everything is
Why aren’t true Cortisol Awakening Response tests readily available? A true CAR assessment
requires salivary samples to be collected at the moment of waking, and twice more, at 30 minutes after waking
and 60 minutes after waking. These specifically timed collections are difficult and impractical with urine and
traditional salivary options. The DUTCH Plus® uses specialty, FDA-approved, and patented collection devices called
Salivettes™. Salivettes™ are specifically made for testing cortisol when timing needs to be precise and
are used in nearly all of the published CAR studies. The small synthetic cotton swab can be quickly saturated
with saliva, providing a very fast and simple collection. Unfortunately for labs using saliva to test reproductive
hormones, they are not a viable option as the swabs cannot be used when testing progesterone. The DUTCH
Plus® offers the most accurate salivary cortisol sampling with Salivette™ collection and analysis using LC-MS/
MS. An unparalleled clinical tool is created when combining salivary cortisol with the extensive urine
metabolites from DUTCH.
