The Hormone Trio - Saliva test measures free oestradiol, progesterone and testosterone using saliva samples. Saliva testing reflects the unbound, bioavailable fraction of these hormones, which are available to tissues at the time of sampling.
Clinically, this profile may be useful when exploring symptoms related to hormonal fluctuation across the menstrual cycle, life stage transitions or sex hormone balance in both women and men. Measuring these three hormones together allows relative balance between oestrogenic, progestogenic and androgenic activity to be reviewed.
Practitioners typically interpret results alongside symptom history, cycle timing, age, medications and other laboratory findings. When reviewed in context, the test can support informed discussions with clients about sex hormone patterns and variability.
