Saliva testing for steroid hormones measures free, bioavailable hormone levels that directly impact tissue function. Unlike blood spot tests, which can be influenced by binding proteins, saliva provides clinically relevant data that reflects the actual hormones your patients’ cells utilize, which can contribute to symptoms.
This method also uncovers daily diurnal rhythms —essential for assessing cortisol— by conveniently capturing hormone levels at key time points throughout the day without the need for needles or clinic visits.
With more relevant data and improved compliance, saliva testing paves the way for better patient health.
