What Does This Test Measure?
Saliva — Advanced Female Hormone Panel (LC-MS/MS): Estrone (E1), Estradiol (E2), Estriol (E3), Progesterone, Testosterone, DHEAS, Cortisol.
7 markers — the most complete single-point oestrogen assessment available in a female saliva panel, combining the full oestrogen triad with progesterone balance, androgen sufficiency, adrenal reserve, and morning cortisol in a single at-home kit.
Related Symptoms
Irregular, heavy, or painful periods, PMS including mood swings, bloating or breast tenderness, perimenopausal or menopausal symptoms including hot flushes and night sweats, low libido, persistent fatigue or low energy despite adequate sleep, anxiety or emotional instability, poor sleep quality or night waking, weight gain particularly around the abdomen, fertility concerns, burnout or chronic stress, or feeling hormonally off despite normal standard blood test results.
Did You Know?
Most female hormone panels measure only estradiol (E2). This profile adds estrone (E1) and estriol (E3), completing the oestrogen triad. In women, estrone becomes the dominant oestrogen after menopause and is primarily produced by adipose tissue via aromatase conversion — making it the key marker of postmenopausal oestrogenic activity. Estriol, by contrast, is the most protective of the three oestrogens and its ratio relative to estradiol and estrone provides clinically meaningful information about oestrogenic balance that E2 alone cannot reveal. The E1:E2:E3 ratio guides decisions about whether oestrogenic support, progesterone supplementation, or adrenal optimisation is the appropriate clinical priority — a level of resolution unavailable from standard hormone panels.
Who Should Consider This Test?
- Irregular, heavy, or painful periods
- PMS — mood swings, bloating, breast tenderness, or irritability
- Perimenopausal or menopausal symptoms — hot flushes, night sweats, brain fog, or low mood
- Low libido or reduced sexual responsiveness
- Persistent fatigue or low energy despite adequate sleep
- Anxiety, depression, or emotional instability
- Difficulty sleeping or waking in the night
- Weight gain or difficulty losing weight, especially around the abdomen
- Fertility concerns or difficulty conceiving
- Symptoms of oestrogen dominance — bloating, breast tenderness, or heavy bleeding
- Postmenopausal women wanting a full oestrogenic status assessment
- Burnout, chronic stress, or emotional exhaustion
- Currently on HRT or bioidentical hormones and wanting a complete oestrogen triad alongside adrenal markers
- Feeling hormonally off but told results are normal on standard blood tests
Why This Test Is Particularly Important for Women
- The full oestrogen triad (E1, E2, E3) reveals oestrogenic source and metabolic balance in women — elevated estrone relative to estradiol indicates adipose-driven aromatisation; a low estriol-to-estradiol ratio indicates a more proliferative oestrogenic environment; these patterns guide HRT selection, progesterone dosing, and lifestyle prioritisation
- Saliva LC-MS/MS measures free, bioavailable estradiol and testosterone — the fractions actually driving symptoms; standard blood immunoassay measures total hormone including the protein-bound inactive fraction, which frequently masks clinically significant imbalances in women on HRT or with elevated SHBG
- The progesterone-to-estradiol ratio is the most clinically meaningful number in this panel — oestrogen dominance drives the majority of PMS, cycle irregularity, breast tenderness, and perimenopausal anxiety even when absolute estradiol appears within range
- DHEAS is the adrenal precursor to both oestrogen and testosterone in women — its inclusion reveals whether adrenal depletion is driving sex hormone decline independently of ovarian function
- Cortisol provides the HPA axis context — elevated morning cortisol suppresses progesterone via pregnenolone steal, depletes DHEAS, and promotes visceral fat-driven aromatase activity, compounding both oestrogen dominance and androgenic insufficiency

Frequently Asked Questions
What hormones does this test measure?
Estrone (E1), Estradiol (E2), Estriol (E3), Progesterone, Testosterone, DHEAS, and Cortisol — 7 markers providing the most complete female oestrogen and hormonal panel available from a single at-home saliva test.
When should I collect my sample during my menstrual cycle?
Day 19–21 of your cycle (approximately 7 days after ovulation) is optimal for capturing progesterone and estradiol in context. Full timing guidance for irregular cycles, perimenopause, postmenopause, and HRT users is included in your kit.
How does this differ from Female Saliva Hormone Profile I?
Profile I measures estradiol, progesterone, testosterone, DHEAS, and morning cortisol — 5 markers. Profile III extends this by adding estrone (E1) and estriol (E3), providing the complete oestrogen triad for a full assessment of oestrogenic source, metabolic balance, and postmenopausal hormonal status.
Can I use this test if I am postmenopausal or on HRT?
Yes. This test is particularly valuable for postmenopausal women and those on HRT wanting the most complete oestrogenic picture to guide therapy decisions and identify whether adrenal or ovarian dysfunction is the primary driver of residual symptoms.
Does the price include the laboratory fee?
Yes. The full laboratory analysis fee is included. There are no additional charges. You are only responsible for posting your sample to the laboratory.
How long is the kit valid for?
The kit must be used within 12 months of the purchase date.
