Hormone Trio — Essential Women's Hormone Panel (Estradiol, Progesterone & Testosterone)
The Hormone Trio is a targeted saliva hormone test measuring the three most important sex hormones for women: estradiol (E2), progesterone (Pg), and testosterone (T). This focused panel provides essential insight into hormonal balance, ratio relationships between estrogen and progesterone, and testosterone levels — making it an efficient, cost-effective option for targeted hormonal assessment.
What's Measured

Estradiol (E2) — the primary reproductive estrogen; supports bone density, mood, libido, and cardiovascular health
Progesterone (Pg) — balances the proliferative effects of estrogen; crucial for sleep, anxiety, uterine health, and mood
Testosterone (T) — influences libido, energy, lean muscle mass, cognitive drive, and emotional resilience in women

Estrogen-Progesterone Ratio: Why It Matters
One of the most clinically important insights from this test is the E2:Pg ratio. "Estrogen dominance" — where estrogen is high relative to progesterone — is a common underlying factor in PMS, fibroids, endometriosis, breast tenderness, weight gain, and mood disorders. The Hormone Trio gives your practitioner the data needed to identify and correct this imbalance naturally.
Who Is This For?
The Hormone Trio is ideal for women with PMS, irregular cycles, perimenopause symptoms, low libido, unexplained mood changes, or those wanting to monitor hormonal health during natural treatment. Results reviewed by Michelle Tonkin ND with personalized recommendations.
Frequently Asked Questions
Q: Is saliva testing better than blood for sex hormones?
A: Saliva measures free (bioavailable) hormones — the fraction actively interacting with your cells — providing clinically more relevant data than total blood hormone levels for many conditions.
Q: When should I take this test?
A: For menstruating women, days 19–21 of your cycle (mid-luteal phase) is optimal for assessing the progesterone-estrogen relationship. Menopausal women and men can test on any day.
