16 markers total — a complete picture of female sex hormone balance, adrenal cortisol rhythm, and cardiometabolic risk in a single at-home kit.
Related Symptoms
Persistent fatigue, unexplained abdominal weight gain, sugar cravings, energy crashes, elevated cholesterol or triglycerides on previous testing, PMS, heavy or irregular periods, perimenopausal or menopausal symptoms (hot flushes, night sweats, low mood), low libido, brain fog, anxiety, insomnia, chronic stress, burnout, diagnosed or suspected PCOS, or family history of diabetes or heart disease.
Who Should Consider This Test?
- Persistent fatigue or exhaustion that does not improve with sleep or rest
- Unexplained weight gain or difficulty losing weight, particularly around the abdomen
- Sugar cravings, energy crashes, or afternoon slumps
- Elevated cholesterol or triglycerides on previous testing
- Blood sugar irregularities, a history of gestational diabetes, or pre-diabetes
- PMS, heavy, irregular, or absent periods
- Breast tenderness, bloating, or mood swings in the second half of the cycle
- Perimenopausal or menopausal symptoms: hot flushes, night sweats, vaginal dryness, low mood
- Low libido or reduced sexual interest
- Brain fog, poor concentration, or memory issues
- Anxiety, irritability, or emotional volatility
- Insomnia, night waking, or unrefreshing sleep
- Chronic stress or burnout
- Diagnosed or suspected PCOS or estrogen dominance
- Currently on HRT and wanting to monitor hormonal and metabolic markers together
- Family history of diabetes, heart disease, or metabolic syndrome
- Women over 35 wanting a comprehensive hormonal and cardiometabolic health baseline
Why This Test Is Particularly Important for Women
- Estrogen is the primary cardiovascular protector in women — Estradiol (E2) supports HDL cholesterol, suppresses LDL oxidation, maintains vascular elasticity, and inhibits systemic inflammation; as E2 declines in perimenopause, HDL falls, triglycerides rise, and hsCRP elevates in a directly hormonal pattern that raises cardiovascular risk yet is rarely assessed alongside hormone levels
- Cortisol is the primary driver of insulin resistance and visceral fat in women — chronic cortisol elevation impairs insulin sensitivity, drives abdominal fat, raises triglycerides, suppresses HDL, and elevates hsCRP; simultaneously suppressing progesterone and creating estrogen dominance
- Insulin resistance is hormonally amplified in women at every life stage — PCOS is defined by insulin resistance even in lean women; perimenopause removes estrogen’s insulin-sensitising effect; fasting insulin is the earliest detectable marker, elevated years before HbA1c becomes abnormal
- hsCRP connects the hormonal and metabolic systems — elevated in women by cortisol dysregulation, insulin resistance, visceral fat, estrogen decline, and progesterone deficiency simultaneously; a stronger independent predictor of cardiovascular disease in women than LDL cholesterol
- Progesterone and DHEAS are the anti-inflammatory, anti-metabolic-ageing hormones in women — both depleted under chronic cortisol elevation; their decline accelerates insulin resistance, cardiovascular risk, and the hormonal deterioration of perimenopause

Frequently Asked Questions
Why should women test hormones and cardiometabolic markers together?
In women, sex hormones and cardiometabolic health are mechanistically inseparable. Estradiol protects HDL and suppresses cardiovascular inflammation; its decline directly raises cardiovascular risk. Cortisol drives insulin resistance and visceral fat while suppressing progesterone. Testing both systems together reveals whether cardiometabolic symptoms are driven by hormonal root causes — something neither system can determine when tested alone.
When in my cycle should I collect my samples?
Guidance on optimal cycle timing is included in the kit. For most women, collection in the luteal phase (days 19–21 of a 28-day cycle) provides the most clinically meaningful progesterone and estrogen values alongside the metabolic markers.
Is this test suitable for women with PCOS?
Yes — this test is particularly valuable for women with PCOS. PCOS is fundamentally a condition of insulin resistance, androgen excess, and estrogen-progesterone imbalance — all directly assessed by this panel. Fasting insulin is often the most clinically important marker in PCOS.
Can I use this test if I am on HRT or the contraceptive pill?
Yes. HRT and the contraceptive pill significantly affect estrogen, progesterone, HDL, triglycerides, and insulin sensitivity — which is precisely why monitoring both hormonal and cardiometabolic markers together is more informative than standard blood tests for women on hormonal treatment.
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 samples to the laboratory.
How long is the kit valid for?
The kit must be used within 12 months of the purchase date.
