Cholesterol checks after 50: why a blood test needs context

Sources cited · not medically reviewed · last checked October 2026

The short answer. High cholesterol usually has no symptoms; a blood test is how it is found.⁸ A result is useful, but it is not a stand-alone prediction. NHS guidance says a GP uses cholesterol alongside factors such as age, blood pressure and health conditions when estimating cardiovascular risk.⁹

What the test measures

A cholesterol test can report total cholesterol, HDL cholesterol and non-HDL cholesterol.⁹ You may see only a total result at first, so it is reasonable to ask whether the other results are available and what they add.⁹

The figures are not a self-diagnosis tool. The NHS says a suitable target depends on age, health conditions and cardiovascular risk; illness and some medicines can also affect results.⁹ This is why copying someone else’s target from the internet is not a useful plan.

When a check may be worth discussing

NHS guidance says to ask about a test if you are over 40 and have not had one before, are overweight, or have a family history of high cholesterol or heart problems.⁸ A GP may also suggest one because of age, weight, high blood pressure or diabetes.⁸

Testing may involve blood taken from the arm, or a finger-prick check through an NHS Health Check or pharmacy. Most people do not need to fast, although you may be asked to do so for up to 12 hours.⁸ Follow the instructions for your test rather than guessing.

What you can influence

The sensible starting point is the same wider pattern that supports metabolic health: regular movement, a balanced food pattern, not smoking, moderating alcohol and discussing weight support where it is appropriate. These are not substitutes for prescribed treatment, and they do not mean every result can be managed the same way.

Do not start, stop or change medication because of an online result. If medicine is discussed, ask what it is intended to change, how its benefit will be reviewed, and what support is available alongside it.

What needs a professional

Take your result back to the clinician or service that arranged the test. Ask how it fits with your blood pressure, blood sugar, family history and other health conditions. That is the risk conversation that matters; one number on its own cannot provide it.⁹

Seek urgent local care for chest pain that does not go away, particularly with sweating, sickness, light-headedness or shortness of breath.³

Questions worth taking to your appointment

Which parts of my cholesterol result matter most in my wider risk picture?
Do I need a repeat test or any other checks?
Does my family history change what you recommend?
Which lifestyle changes are most useful for me?
If medication is discussed, how will we review whether it is right for me?
