Saliva hormone testing is a non-invasive, scientifically validated method for measuring the bioavailable fraction of key hormones — including cortisol, oestrogen, progesterone, testosterone, and DHEA — from the comfort of home. Unlike standard blood tests, which measure total hormone levels including the inactive, protein-bound fraction, saliva testing reflects the hormones that are actually active in tissues and driving biological effects. Combined with LCMS (liquid chromatography tandem mass spectrometry) technology, saliva testing offers exceptional accuracy, sensitivity, and clinical relevance for assessing hormone balance, monitoring hormone therapy, and understanding the root causes of symptoms such as fatigue, mood changes, poor sleep, and hormonal imbalance.

Learn the science of saliva testing, how it measures bioavailable hormones, and why it’s trusted by patients, clinicians, and wellness experts.
