Why Do We Test Hormones in Saliva?

Why Do We Test Hormones in Saliva?


Saliva testing is used for measuring hormones like cortisol, estrogen and testosterone, and its non-invasive collection asks patients to spit into a plastic tube. This sampling method allows patients to collect saliva at home at specific times, which is important for accurately measuring hormone levels.

Why do we test hormones in saliva? Steroid hormones in the bloodstream are 95-99% bound to carrier proteins, and in this form are unavailable to target tissues. Saliva testing measures the amount of hormone available to target tissues – the bioavailable amount. For this reason, saliva testing better relates to specific symptoms of excess or deficiency, and is a good option for monitoring hormone therapy.

ZRT is one of the first labs to measure hormones in saliva, and helped establish the method that made saliva hormone testing commercially viable for health care providers and patients around the globe.

Choosing and Using the Right Product

Ranges Adjusted for Supplementation:
Unlike other labs, patients do not need to stop hormone supplementation to use ZRT’s testing because we have ranges adjusted for age, menstrual status and supplementation types. This is the ideal method for tracking the effectiveness of hormone treatments.

No Pooling:
ZRT does not pool patient samples, meaning that they don’t mix multiple daily samples together to get an average hormone level. Instead theyt measure hormones from a single morning sample, which represents the peak of daily hormone production – the optimal time to measure.

ZRT is the only lab to perform an extraction process for saliva testing, which separates hormones from background contamination. This is the only way to assure accurate test results for low-concentration hormones such as estradiol.

Setting Industry Standards:
ZRT initiated and manages the industry-wide standards program called the Saliva Proficiency Inter-laboratory Testing Program – which enables laboratories to regularly evaluate and improve saliva testing accuracy.
