Do I need this if I feel fine?
Honestly, probably not — and we will say so.
General screening in men without symptoms has not been shown to reduce death or serious illness, and broad panels generate borderline results that lead to more testing.
The NHS Health Check covers the things that matter, free, if you are between 40 and 74.
Should PSA be included?
Only after a proper conversation, not as a default.
There is no national prostate screening programme because the balance is genuinely close. Most raised PSA results are not cancer, and overdiagnosis is a real harm.
What shifts the argument towards testing: a family history, and Black African or Caribbean heritage. See the PSA page for the full picture.
How should I prepare?
Fasting is usually required.
If testosterone is included, book a morning appointment — ideally between 7am and 10am, because levels fall through the day and a later sample is not reliably interpretable.
My testosterone came back low. What does that mean?
On one sample, not much. Diagnosis needs two low morning samples plus symptoms.
Recent illness, poor sleep, stress and weight gain all lower it temporarily, and levels often normalise on a repeat.
My liver results were slightly abnormal. Should I worry?
Usually it is fatty liver, and it is both common and reversible.
Around 7 to 10 per cent weight loss substantially improves it, as does cutting alcohol. It is one of the few screening findings that both matters and responds.
What does prediabetes mean?
That blood sugar is above normal but below the diabetes threshold — a warning, not a diagnosis.
The NHS Diabetes Prevention Programme is free and roughly halves progression in people who complete it. It is the most useful thing a raised HbA1c can lead to.
Why does blood pressure keep coming up?
Because it matters more than most of this panel and we cannot measure it.
High blood pressure is silent, which is exactly why it is worth checking when you feel well. Many pharmacies do it free without an appointment.
I am tired and my libido is low. Is that testosterone?
Sometimes — but more often it is something else.
Sleep apnoea, iron deficiency, thyroid disease, depression and untreated diabetes all produce that picture, and sleep apnoea both mimics low testosterone and causes it.
Which is why the whole panel is read together, rather than reaching for one number.
What is the most useful free thing I could do?
Return the bowel screening kit if you are over 50. Men return it less often than women, it takes minutes, and it is one of the few screening tests proven to save lives.
