Test ID: SB-641 | Saliva 4-Point Cortisol + Blood Spot CardioMetabolic Panel
The Female CardioMetabolic & Cortisol Test Kit is a comprehensive at-home health assessment designed specifically for women, measuring 10 key markers across the full daily cortisol rhythm, blood sugar regulation, systemic inflammation, and cardiovascular health. It combines a 4-point saliva cortisol profile with a blood spot cardiometabolic panel — providing an integrated picture of the stress-metabolism axis that standard GP blood tests do not assess together.
In women, cortisol, blood sugar, and cardiovascular risk are not independent concerns. They are tightly connected through oestrogen, progesterone, and the hormonal shifts of the menstrual cycle, perimenopause, and menopause. Chronic cortisol dysregulation is one of the most significant and most underrecognised drivers of insulin resistance, visceral fat accumulation, inflammation, and cardiovascular risk in women — and its impact worsens at every hormonal transition. This test measures the full picture in a single at-home kit.
Test from home with confidence — no clinic visit required. Results within 3–5 working days.
Why This Test Is Particularly Important for Women
Women experience a distinct and frequently overlooked pattern of cardiometabolic risk that is directly shaped by hormonal biology:
- Cortisol dysregulation is hormonally amplified in women — progesterone modulates the HPA axis and buffers cortisol; as progesterone declines during the luteal phase, perimenopause, and menopause, cortisol rises relatively — driving blood sugar instability, visceral fat, inflammation, and cardiovascular risk in a pattern that is unique to women
- Insulin resistance in women is hormonally driven — cortisol, low progesterone, and declining oestrogen all independently impair insulin sensitivity; PCOS is characterised by insulin resistance even in lean women, and the perimenopause transition markedly raises metabolic risk even in previously metabolically healthy women
- Women’s cardiovascular risk is systematically underestimated — before menopause, oestrogen protects HDL cholesterol and suppresses vascular inflammation; after menopause, LDL rises, HDL falls, triglycerides increase, and hsCRP elevates in a pattern that raises cardiovascular disease risk to match or exceed that of men — yet women are less likely to be tested or treated
- Chronic stress accelerates metabolic ageing in women — elevated cortisol drives visceral fat deposition, raises triglycerides and hsCRP, impairs glucose uptake, and promotes the oestrogen-cortisol imbalance that characterises premature metabolic deterioration in women under sustained stress
- hsCRP connects the entire picture — elevated C-reactive protein in women reflects the intersection of cortisol dysregulation, insulin resistance, visceral fat, and oestrogen decline; it is one of the strongest predictors of cardiovascular disease in women — more predictive than LDL cholesterol alone
What This Test Measures
Saliva — 4-Point Cortisol Profile
- Morning Cortisol: The Cortisol Awakening Response — the morning cortisol surge that sets energy, blood sugar regulation, and hormonal tone for the day. In women, a healthy morning cortisol peak supports progesterone balance and metabolic function; dysregulation here cascades across all other markers. A blunted response signals burnout; an exaggerated response indicates high stress reactivity.
- Noon Cortisol: Elevated noon cortisol in women impairs insulin sensitivity, promotes blood sugar instability, drives afternoon energy crashes and sugar cravings, and raises triglycerides and hsCRP — effects that are amplified in the luteal phase and during perimenopause.
- Evening Cortisol: Should be declining significantly by early evening to allow progesterone and melatonin to rise, supporting hormonal restoration and overnight metabolic recovery. Elevated evening cortisol in women disrupts sleep, blood sugar regulation, and inflammatory resolution overnight.
- Night Cortisol: Elevated night cortisol is a primary driver of insomnia, night sweats, and overnight blood sugar dysregulation in women — particularly during perimenopause and menopause, when progesterone is no longer available to buffer cortisol at night.
Blood Spot — CardioMetabolic Panel
- Fasting Insulin: The earliest detectable marker of insulin resistance — elevated years before HbA1c or fasting glucose becomes abnormal. In women, elevated fasting insulin is directly driven by cortisol excess, low progesterone, PCOS, and the oestrogen decline of perimenopause. It also promotes visceral fat and systemic inflammation, compounding cardiometabolic risk.
- HbA1c (Glycated Haemoglobin): Reflects average blood sugar regulation over the preceding 8–12 weeks. Women’s risk of pre-diabetes and type 2 diabetes rises markedly after menopause as oestrogen’s insulin-sensitising effects are lost; HbA1c provides the medium-term blood sugar picture that a single fasting glucose measurement cannot.
- HDL Cholesterol: The protective cardiovascular fraction directly supported by oestrogen. HDL typically falls significantly after menopause, removing a key protection against cardiovascular disease. Low HDL is also a reliable marker of insulin resistance and metabolic syndrome in women.
- Triglycerides: Strongly associated with cortisol elevation, insulin resistance, and oestrogen decline in women. Elevated triglycerides often rise before LDL changes and are a primary cardiometabolic risk marker — particularly relevant for perimenopausal and postmenopausal women.
- Total Cholesterol: Provides the overall lipid context. Rising total cholesterol in perimenopausal and postmenopausal women is a direct and predictable consequence of declining oestrogen and requires integrated assessment alongside HDL and triglycerides.
- hsCRP (High-Sensitivity C-Reactive Protein): The gold standard systemic inflammation marker. In women, elevated hsCRP reflects the convergence of cortisol dysregulation, insulin resistance, visceral fat, and oestrogen decline. It is one of the strongest independent predictors of cardiovascular disease in women — more powerful than LDL cholesterol — and is a key target for lifestyle and hormonal intervention.

Frequently Asked Questions
What does this test measure?
4-point Cortisol (saliva: morning, noon, evening, night) plus Fasting Insulin, HbA1c, HDL Cholesterol, Triglycerides, Total Cholesterol, and hsCRP (blood spot) — 10 markers in total.
Why test cortisol and cardiometabolic markers together in women?
In women, cortisol is the primary hormonal driver of insulin resistance, visceral fat, elevated triglycerides, reduced HDL, and systemic inflammation. The relationship between cortisol and cardiovascular risk is direct, hormonally amplified, and worsens at every life stage transition. Assessing both together reveals the root cause of metabolic symptoms that treating markers in isolation misses.
When should I collect my samples during my cycle?
This test can be taken at any point in your cycle. Guidance on optimal timing is included in the kit. Collecting during a representative period of your typical stress and lifestyle pattern gives the most clinically useful results.
Can I use this test if I am on HRT or the contraceptive pill?
Yes. HRT and hormonal contraception affect lipid profiles and blood sugar regulation, which is precisely why monitoring these markers alongside cortisol provides a more complete picture of your metabolic health. Follow the timing guidance in your kit.
How accurate is the test?
Blood spot samples are analysed using advanced immunoassay technology; saliva cortisol is measured using LC-MS/MS — the gold standard for bioavailable hormone measurement.
When will I get my results?
Within 3–5 working days after your samples reach the laboratory.
Are there hidden costs?
No. Laboratory analysis and specialist review are fully included. You are responsible for postage to the lab.
How long is the kit valid?
12 months from purchase.
