Your 40s are when the gap between how you feel and what is happening inside your body starts to widen. Cardiovascular risk accelerates. Hormones decline. Metabolic efficiency drops. Cancer risk rises. The NHS Health Check every 5 years is not built for this. Annual comprehensive testing is.
Your body does not suddenly break at 40. But several systems begin declining gradually, and without testing, you will not know which ones are moving until symptoms appear, sometimes years later.
Atherosclerotic plaque accumulates over your lifetime. By 40, the cumulative exposure to atherogenic particles (measured by ApoB) has had decades to do damage. This is when cardiovascular events start becoming statistically more common. ApoB and Lp(a) reveal your actual particle burden and genetic risk. A standard cholesterol test does not.

In men, testosterone drops approximately 1-2% per year from age 30. By 45, the cumulative decline is significant. In women, perimenopause typically begins in the mid-40s with fluctuating oestrogen, declining progesterone, and rising FSH. Both sexes experience declining DHEA-S and shifting cortisol patterns. Without a baseline from your 30s, you cannot quantify the change. Without testing now, you cannot see where you stand. Hormone testing guide →
Prostate cancer is the most common cancer in men in the UK, with risk increasing sharply after 40. PSA with free ratio is the primary screening marker. In women, CA-125 (ovarian) and CA 15-3 (breast) provide an additional screening layer. The NHS does not routinely offer these markers as part of a general health check. TrueVitals Ultimate includes all of them.
Insulin sensitivity declines with age, accelerated by reduced muscle mass, increased visceral fat, and decreased physical activity. By 40, many people are insulin resistant without knowing it. Fasting insulin and HOMA-IR catch this years before glucose or HbA1c shift. Metabolic testing guide →
Autoimmune thyroid disease (Hashimoto's) prevalence increases with age, particularly in women. Subclinical hypothyroidism causes fatigue, weight gain, brain fog, and depression that are often attributed to "just getting older." Full thyroid testing (TSH, Free T3, Free T4, antibodies) catches it. TSH alone misses it. Thyroid testing guide →
eGFR (estimated glomerular filtration rate) naturally declines with age. Monitoring kidney function becomes important for anyone on long-term medication, with hypertension, or with diabetes risk. Cystatin C is a more accurate marker of kidney function than creatinine alone, particularly in people with higher muscle mass. TrueVitals Ultimate includes both.
Calcium, phosphate, ALP, vitamin D, and parathyroid hormone (PTH) together assess bone health. For women approaching menopause, the decline in oestrogen accelerates bone loss. For men, low testosterone and vitamin D deficiency contribute. Catching these shifts early opens a window for prevention through supplementation and lifestyle changes.
The NHS Health Check is offered to adults aged 40 to 74 every 5 years. It is a valuable public health initiative, but it was designed for population-level screening, not individual health optimisation.
Checks: BMI, blood pressure, basic cholesterol, diabetes risk score, and smoking/alcohol assessment. Does not include: hormones, full thyroid, ApoB, Lp(a), PSA, tumour markers, insulin, kidney depth, liver depth, iron studies, vitamins, or inflammatory markers. Frequency: once every 5 years. Report: verbal feedback or brief letter.
Tests 114 biomarkers across every major health system including everything the NHS checks plus hormones, full thyroid, advanced lipids, metabolic depth, tumour markers, immune function, iron studies, vitamins, and urinalysis. Frequency: annual or 6-monthly. Report: 30+ page AI-powered personalised analysis with medical review.
The NHS Health Check is free and worth doing. But if you are serious about understanding your health as you age, it is the starting point, not the finish line. Full NHS vs private comparison.
One comprehensive blood test per year costs less than a gym membership. It provides more actionable health data than a decade of sporadic GP visits. And it catches problems at the stage where they are most treatable and least expensive to manage.
The value of annual testing is not just the snapshot. It is the trend. A single result tells you where you are. Two results a year apart tell you which direction you are moving. A PSA of 2.1 is normal. A PSA that has risen from 1.2 to 2.1 in 12 months is a trajectory worth investigating. ApoB creeping from 0.8 to 1.0 over two years signals worsening cardiovascular risk before it reaches a clinical threshold.
Annual comprehensive testing after 40 is the health equivalent of an annual financial review. You would not go five years without checking your pension. Your body deserves the same attention.
114 biomarkers. Full hormones, PSA (men) / CA-125 + CA 15-3 (women), ApoB, Lp(a), insulin, HOMA-IR, full thyroid with antibodies, cystatin C, immunoglobulins, full iron studies, bone markers, and complete urinalysis. The most comprehensive private blood test in the UK. Covers every system that matters after 40. View Ultimate →
200+ biomarkers processed by Randox Health. Everything in Ultimate plus neurological markers, digestive health (H. pylori, pepsinogen, gastrin), extended autoimmune profiling, metabolic syndrome assessment, and physical measurements (BP, waist, hip, height, weight, pulse). For those who want nothing left unchecked. View Signature →
At minimum: PSA with free ratio (men), full lipid panel with ApoB and Lp(a), HbA1c and fasting insulin, full thyroid with antibodies, complete hormones, kidney function (cystatin C, eGFR), full iron studies, vitamin D, B12, and tumour markers. TrueVitals Ultimate (114 markers, £349) covers all of these in a single test.
The NHS Health Check is a useful baseline but only covers BMI, blood pressure, basic cholesterol, and diabetes risk. It does not include hormones, thyroid, PSA, ApoB, Lp(a), insulin, kidney depth, tumour markers, or vitamins. It is offered every 5 years, which is insufficient for catching trends. Annual comprehensive testing provides significantly more data.
Annually at minimum. Every 6 months if you are on medication, managing risk factors, or actively optimising health. Lp(a) only needs testing once (it is genetic). PSA, hormones, and metabolic markers benefit from annual tracking to identify trends. The trend is more informative than any single result.
Yes. Prostate cancer is the most common cancer in men in the UK. PSA screening is particularly important from 40, or earlier with a family history. TrueVitals Ultimate includes PSA, free PSA, and the PSA ratio. The ratio helps differentiate benign enlargement from potential malignancy. Men's health guide.
No. While an earlier baseline is ideal, your first comprehensive test at 40 establishes your reference point for everything going forward. It also catches any existing issues that have developed silently. Many of our customers test for the first time in their 40s and wish they had started sooner, but starting now is far better than not starting at all.
