What to Get, When to Get It, and What the NHS Won't Tell You to Ask For

The NHS catches emergencies brilliantly. Preventing the slow decline that starts in your 40s is a different matter. Here is what you're entitled to, what to push for, and what to consider privately — by decade.

Your 40s

The decade when atherosclerosis, insulin resistance and blood pressure problems are already underway — silently. The best time to get your first real baseline.

NHS — you're entitled to this

NHS Health Check (40–74, every 5 years)

Blood pressure

Cholesterol & blood sugar

Cervical screening (women, to age 64)

Ask your GP for these

ApoB & Lp(a) — heart risk markers the standard panel misses

Fasting insulin — catches insulin resistance years early

Vitamin D & ferritin

Thyroid (TSH)

Worth considering privately

Full body skin check if you've had significant sun exposure

Fitness test (VO2 max) — your most important longevity number

Your 50s

Cancer screening programmes kick in. Bone density, heart disease and cognitive health all need attention. The decade where early action has the biggest payoff.

NHS — you're entitled to this

Bowel cancer screening (every 2 years from 50 in Scotland; 60 in England — check your letter)

Breast screening (women, from 50, every 3 years)

NHS Health Check (if not done recently)

Shingles vaccine (from 70, but discuss timing now)

Ask your GP for these

DEXA bone density scan — especially for women post-menopause

PSA test (men) — prostate screening, discuss risks honestly with your GP

Inflammation marker (hsCRP)

Full eye exam including pressure check (glaucoma)

Worth considering privately

Heart scan (CAC score) — especially with family history of heart disease

Skin cancer check with a dermatologist

Hearing test — hearing loss in your 50s raises dementia risk

Your 60s

Falls, fractures, cognitive decline and cardiovascular events become real risks. Staying on top of the full picture matters more than ever.

NHS — you're entitled to this

Bowel cancer screening continues

Breast screening continues (to 70)

Aortic aneurysm scan (men at 65 — one-off NHS invite)

Annual flu & pneumonia vaccines

Shingles vaccine (70–79)

Ask your GP for these

Repeat bone density scan if first showed thinning

Full medication review — polypharmacy becomes a risk in your 60s

Annual blood panel including kidney and liver function

Cognitive baseline assessment — a useful reference point even without symptoms

Worth considering privately

Colonoscopy if bowel screening flagged anything

Carotid artery scan if cardiovascular risk is elevated

Repeat biological age test to track progress

Three Things Most People Miss

Hearing

Untreated hearing loss in midlife is one of the strongest modifiable risk factors for dementia. Most people wait a decade too long.

Skin

A full body skin check by a dermatologist isn't on any NHS programme. Melanoma caught early is almost always curable. Caught late, rarely.

Teeth

Gum disease is directly linked to cardiovascular disease and diabetes. A regular dental check is a longevity intervention, not just hygiene.

What the standard check-up misses

HbA1c measures average blood glucose over the past three months. It's offered on the NHS if you're at risk of diabetes — but by the time HbA1c is elevated into the pre-diabetic range, insulin resistance has typically been building for years. A more sensitive early marker is fasting insulin. Most people with deteriorating insulin sensitivity have normal fasting glucose for a long time before it shows up in standard tests. Fasting insulin, combined with fasting glucose, allows calculation of HOMA-IR — a straightforward index of insulin resistance. It's a cheap blood test. It's not routinely offered. And it tells you something important about metabolic health well before the standard markers flag anything.

ApoB is arguably the most important cardiovascular risk marker that most people have never heard of. Standard cholesterol tests measure LDL cholesterol — the concentration of cholesterol in low-density lipoprotein particles. ApoB measures the number of those particles directly. A particle count is more predictive of cardiovascular risk than the cholesterol concentration within them, because it's the particles themselves that penetrate arterial walls and initiate atherosclerosis. Two people can have identical LDL cholesterol but very different ApoB counts — and therefore very different risk profiles. Cardiovascular disease kills around 160,000 people in the UK every year. ApoB is not part of the standard NHS lipid panel. It's available privately for around £30–£50, and increasingly some GPs will request it.

VO2 max — the maximum rate at which your body can use oxygen during exercise — is one of the strongest predictors of all-cause mortality in the research literature. A landmark study in JAMA found that low cardiorespiratory fitness was a stronger risk factor for death than smoking, hypertension, or diabetes in the populations studied. It's not a blood test; it's a functional measure, typically assessed via a graded exercise test. It can also be estimated reasonably well through fitness trackers and some smartwatches. No routine check-up measures it. But it may be the single most useful number for understanding how well your cardiovascular and metabolic systems are actually functioning.

What the NHS does offer — and why it matters more than people act on it

The screening programmes that do exist in the UK are, in some cases, exceptionally good — and underutilised. Bowel cancer screening is offered to everyone aged 50 to 74 every two years via a home stool test (FIT), with colonoscopy follow-up for positive results. Bowel cancer is the fourth most common cancer in the UK and the second biggest cancer killer. Detected at stage one, survival rates exceed 90%. Detected at stage four, they fall below 10%. The FIT test takes five minutes. Around one in three people who receive a kit don't return it.

Breast screening via mammogram is offered every three years to women aged 50 to 71. The evidence on breast screening is more contested than for bowel cancer — it does detect cancers early, but also leads to some overdiagnosis and overtreatment. The current consensus is that the benefit outweighs the harm for most women in the invited age range, but it's worth understanding what a positive finding does and doesn't mean before the screening rather than after.

Abdominal aortic aneurysm screening is offered to men at age 65 — a one-time ultrasound scan that takes ten minutes and can detect a potentially fatal ballooning of the aorta before it ruptures. It has essentially no downsides. The uptake rate is around 75%, which means roughly one in four eligible men don't attend. For a test with no cost, no preparation, and clear benefit, that is a striking gap.

The tests worth considering privately

Beyond NHS provision, a handful of tests are worth knowing about for anyone serious about monitoring their longevity trajectory. A DEXA scan measures bone density and body composition — not just weight, but the ratio of lean mass to fat mass, and where fat is distributed. Visceral fat — the fat around internal organs — is metabolically active in a harmful way and strongly associated with cardiovascular and metabolic disease risk. A standard BMI reading tells you almost nothing about this. A DEXA scan, available privately for around £100–£150, tells you a great deal.

Coronary artery calcium scoring — a low-dose CT scan of the heart — can detect calcified plaques in the coronary arteries before any symptoms develop. A score of zero means essentially no calcified plaque and a very low near-term cardiovascular risk, even in people with elevated cholesterol. A high score means atherosclerosis is already established and aggressive prevention is warranted. It is one of the most informative single tests for cardiovascular risk available, and many cardiologists consider it underused. It costs around £200–£400 privately and involves a small radiation dose — roughly equivalent to a transatlantic flight.

For those interested in a broader biological age assessment, epigenetic clock testing measures methylation patterns across the genome to estimate biological age. Several commercial versions exist (TruAge, Elysium Index, others). The science behind them is real — epigenetic clocks developed by researchers like Steve Horvath have shown strong correlations with health outcomes in research settings. The commercial tests are improving but vary in quality. Treat the result as directional information rather than a precise measurement.

'The tests that tell you the most about how fast you're ageing are rarely the ones you'll be offered. Knowing which ones to ask for is half the battle.'

How to approach this practically

Start with what's free. If you're eligible for NHS screening programmes — bowel, breast, cervical, AAA — attend them. They exist because the evidence supports them. Then consider a private blood panel that goes beyond the standard: ask specifically for ApoB, fasting insulin, HbA1c, full thyroid panel, vitamin D, and an inflammatory marker such as high-sensitivity CRP. Many private GPs and services like Medichecks or Bluecrest offer comprehensive panels for £150–£300.

If you have cardiovascular risk factors — family history, elevated ApoB, high blood pressure, or a decade or more of suboptimal diet — discuss coronary artery calcium scoring with your GP or a cardiologist. If you're uncertain about your metabolic health, HOMA-IR from a fasting blood draw is a low-cost, high-information starting point. And if you want a functional measure of cardiovascular fitness without a lab test, most modern fitness trackers will estimate VO2 max from resting heart rate and activity data — imperfect, but useful for tracking trend over time.

The bigger point is this. The gap between what you're offered and what you could know is not insurmountable. A modest investment in the right tests, done at the right time, can catch things that would otherwise go undetected for years. The earlier you have that information, the more options you have for acting on
