Test ID: SB-641 | Saliva 4-Point Cortisol + Blood Spot CardioMetabolic Panel
The Male CardioMetabolic & Cortisol Test Kit is a comprehensive at-home health assessment designed specifically for men, 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 is the most consequential and most undertested aspect of men’s long-term health.
In men, cortisol, blood sugar, and cardiovascular risk do not operate independently — they are components of a single metabolic system that also governs testosterone availability, body composition, and cognitive performance. Chronic cortisol dysregulation is one of the most significant and most underdiagnosed drivers of insulin resistance, visceral fat accumulation, testosterone decline, inflammation, and premature cardiovascular disease in men. This test measures all of them together 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 Men
Men carry a disproportionate burden of cardiometabolic disease, yet the hormonal drivers behind it — cortisol excess, insulin resistance, and testosterone decline — are rarely assessed together in routine healthcare:
- Cortisol is the primary driver of visceral fat in men — chronically elevated cortisol directs fat storage to the abdomen, where visceral adipose tissue becomes metabolically active: raising insulin resistance, increasing aromatase activity (converting testosterone to oestrogen), elevating triglycerides, suppressing HDL, and driving systemic inflammation through hsCRP — a compounding cycle that standard cholesterol panels do not reveal
- Insulin resistance accelerates testosterone decline — elevated insulin promotes visceral fat and aromatase-driven oestrogen conversion; simultaneously, low testosterone worsens insulin resistance, creating a feedback loop that drives metabolic syndrome, erectile dysfunction, and cardiovascular risk simultaneously in men
- Cortisol suppresses testosterone directly — through pregnenolone steal and HPA axis dysregulation, chronic cortisol elevation depletes testosterone, impairs Leydig cell function, and suppresses libido, motivation, and physical performance while simultaneously driving all cardiometabolic risk factors upward
- Men’s cardiovascular risk is hormonally driven — low testosterone, high cortisol, insulin resistance, and visceral fat each independently raise LDL, triglycerides, and hsCRP; their combination in chronically stressed or hormonally declining men creates a compounding cardiovascular risk profile that is almost never assessed in its entirety in routine GP care
- hsCRP is the critical missing marker — in men, elevated C-reactive protein reflects the intersection of cortisol dysregulation, insulin resistance, visceral fat, and testosterone decline; it is one of the strongest independent predictors of cardiovascular events, type 2 diabetes, and metabolic disease progression in men
What This Test Measures
Saliva — 4-Point Cortisol Profile
- Morning Cortisol: The Cortisol Awakening Response — the morning cortisol surge that activates metabolism, sets testosterone availability for the day, and establishes cognitive and physical readiness. A blunted response signals adrenal burnout and impaired recovery; an exaggerated response indicates high stress reactivity and morning testosterone suppression.
- Noon Cortisol: Elevated noon cortisol in men promotes insulin resistance, visceral fat accumulation, and aromatase-driven testosterone-to-oestrogen conversion — driving afternoon energy crashes, sugar cravings, and the fat-storage pattern that is the hallmark of cortisol-driven metabolic dysfunction in men.
- Evening Cortisol: Should be declining significantly by early evening to allow testosterone and growth hormone to begin rising during the first sleep cycles. Elevated evening cortisol in men is a direct suppressor of overnight hormonal and metabolic recovery.
- Night Cortisol: Elevated night cortisol suppresses the deep sleep phases during which the majority of daily testosterone is produced. It also drives overnight blood sugar dysregulation and prevents the anti-inflammatory restoration that should occur during sleep — a primary cause of elevated hsCRP and persistent metabolic inflammation in men.
Blood Spot — CardioMetabolic Panel
- Fasting Insulin: The earliest detectable marker of insulin resistance in men — elevated years before HbA1c or fasting glucose becomes abnormal. In men, elevated fasting insulin directly promotes visceral fat accumulation, increases aromatase activity and oestrogen conversion, independently raises cardiovascular risk, and is closely associated with low testosterone and erectile dysfunction.
- HbA1c (Glycated Haemoglobin): Reflects average blood sugar regulation over the preceding 8–12 weeks. Men with chronically elevated cortisol and low testosterone have significantly elevated risk of pre-diabetes and type 2 diabetes; HbA1c captures the medium-term blood sugar picture that a single fasting glucose measurement cannot provide.
- HDL Cholesterol: The protective cardiovascular fraction. Low HDL in men is a reliable marker of insulin resistance, visceral fat, and metabolic syndrome; it is directly suppressed by cortisol excess and low testosterone — two of the most common hormonal patterns in men under chronic stress.
- Triglycerides: Elevated triglycerides are a hallmark of cortisol-driven metabolic dysfunction and insulin resistance in men. They rise before LDL changes, are directly worsened by high cortisol and low testosterone, and are a primary cardiovascular risk marker in men — particularly relevant for those with abdominal fat accumulation.
- Total Cholesterol: Provides the overall lipid context. In men with hypothyroid-like cortisol-driven suppression, low testosterone, and insulin resistance, rising total cholesterol is a predictable consequence that requires integrated hormonal and metabolic assessment.
- hsCRP (High-Sensitivity C-Reactive Protein): The gold standard systemic inflammation marker. In men, elevated hsCRP directly reflects the intersection of cortisol dysregulation, insulin resistance, visceral fat, and testosterone decline. It is one of the strongest independent predictors of cardiovascular events, metabolic disease, and all-cause mortality in men — and a critical target for hormonal and lifestyle intervention.
Who Should Consider This Test?

- Sugar cravings, energy crashes, or afternoon slumps
- Poor recovery from exercise or sustained high workload
- Elevated cholesterol or triglycerides on previous testing
- Blood sugar irregularities or a family history of type 2 diabetes
- Low libido or reduced sexual interest
- Erectile dysfunction or reduced performance
- Chronic stress, burnout, or sustained high workload
- Insomnia, night waking, or unrefreshing sleep

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 men?
In men, cortisol is the primary hormonal driver of visceral fat, insulin resistance, testosterone suppression, and cardiovascular inflammation. The relationship is direct and compounding: cortisol drives visceral fat, which drives aromatase and oestrogen conversion, which further suppresses testosterone and raises cardiovascular risk. Assessing both cortisol and cardiometabolic markers together reveals the root cause and full extent of hormonal and metabolic dysfunction that treating each marker in isolation misses.
Can I use this test if I am on TRT?
Yes. This test is particularly valuable for men on TRT who want to understand whether cortisol dysregulation or insulin resistance is limiting the effectiveness of testosterone therapy or contributing to ongoing metabolic symptoms.
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.
