Overview

A standard PSA test is a blunt instrument. Around three in four men with a raised PSA turn out not to have cancer, and some men with prostate cancer have a normal PSA — yet a raised result routinely leads to MRI and biopsy, with all the anxiety and risk that involves.

We use an enhanced prostate profile rather than PSA alone. Alongside total and free PSA it measures three additional markers and produces a calculated risk score, designed specifically to separate men at genuinely higher risk from those who can safely be reassured.

It is not a perfect test — no prostate test is — but it is a meaningfully better one, and the consultation still covers what the result can and cannot tell you before you decide to proceed.

What this test measures

Total PSA and free PSA, plus interleukin-8, monocyte chemotactic protein-1 and epidermal growth factor — markers of the inflammatory environment around the prostate. These are combined into a calculated prostate cancer risk score.

PSA alone rises with cancer but equally with benign enlargement, infection, recent ejaculation, cycling and simple ageing, which is why the additional markers matter.

Why you might need it

Urinary symptoms, a family history of prostate cancer, being of Black ethnicity, which carries higher risk, or being over 50 and wanting to consider screening.

What's included

Included: total prostate specific antigen · free prostate specific antigen · interleukin-8 · monocyte chemotactic protein-1 · epidermal growth factor · calculated prostate cancer risk score.

A plain total PSA test is available on its own if you would prefer, or if a specialist has asked specifically for that.

How the referral works

Partner site:

Randox Health

Counselling consultation first, then a referral to a Randox Health clinic if you decide to proceed, then a results review with a clear plan.

Preparation required

Avoid ejaculation for 48 hours and vigorous exercise or cycling for 48 hours beforehand — both raise PSA. Postpone the test for at least six weeks after a urinary infection or prostate procedure.

Understanding your results

PSA is not a cancer test

It measures a protein made by the prostate, and it rises for several reasons — most of them not cancer. Benign enlargement, infection, prostatitis, recent ejaculation, cycling and a recent catheter all raise it.

A raised PSA means "this needs looking into", not "you have cancer". Most men with a raised PSA turn out not to have it.

What the numbers roughly mean

Thresholds rise with age, because the prostate enlarges naturally. What matters as much as the absolute figure is:

  • The trend over time — a rising PSA across serial tests is more informative than any single value
  • The free-to-total ratio — a lower proportion of free PSA points more towards cancer, a higher proportion towards benign enlargement
  • Your risk profile — family history, and Black African or Caribbean heritage, which carries substantially higher risk

What a raised result leads to

Not straight to biopsy. Current UK practice is multiparametric MRI first, which frequently avoids a biopsy altogether and, where one is still needed, targets it far better than the older approach.

That change matters, and it is worth knowing before deciding whether to test — the pathway is considerably less unpleasant than its reputation.

Finasteride halves it

If you take finasteride or dutasteride — for hair loss or prostate enlargement — your PSA is roughly halved. The result must be doubled to be interpreted.

Tell any doctor checking your PSA that you take it. This is missed regularly, and it produces falsely reassuring results.

What this test cannot tell you

The honest position on PSA

There is no national prostate screening programme in the UK, and that is a deliberate decision rather than an oversight. The evidence is finely balanced, and it is worth understanding why before testing.

What it gets wrong in both directions

  • False positives are common. Most men with a raised PSA do not have cancer — and the investigation that follows carries anxiety and, where biopsy is needed, some risk
  • False negatives happen. A normal PSA does not exclude prostate cancer, and a proportion of significant cancers occur with unremarkable levels
  • Overdiagnosis is the real issue. Some prostate cancers found by screening would never have caused symptoms or shortened life — but once found, they are difficult to leave alone, and treatment carries risks of incontinence and erectile dysfunction

What it cannot tell you

Whether a cancer, if present, is the aggressive kind. That needs MRI and biopsy. PSA cannot distinguish an indolent cancer from a dangerous one, which is precisely the problem.

Where the balance shifts towards testing

A family history of prostate cancer, and Black African or Caribbean heritage, both raise risk substantially — and in those groups the argument for testing, and for testing earlier, is considerably stronger.

Costs explained

What you pay

  • £40 for the consultation — which here is the product rather than the blood test
  • The test, quoted before it is arranged
  • £40 for the results review

The free route

Any man over 50 can request a PSA test free from his NHS GP, after a discussion about the pros and cons. Men at higher risk — family history, or Black African or Caribbean heritage — should be having that conversation earlier, from around 45.

That entitlement is under-known, and it is worth stating plainly: you do not have to pay for this.

Where the fee earns its place

Twenty minutes to have the decision properly, rather than a yes or no. What a raised result would lead to, what overdiagnosis means, and where your own risk sits.

It is a decision that deserves more time than it usually gets, and that is the honest case for paying.

Where not to spend money

  • Repeat PSA testing every few months without a reason. Ejaculation, cycling and infection all move it, and frequent testing generates alarm rather than information
  • "Prostate support" supplements — saw palmetto and similar. The evidence does not support the price, and some may affect PSA readings
  • Private MRI before a proper discussion, which puts the investigation ahead of the decision

Common questions

Should I have a PSA test?

It is a decision worth twenty minutes rather than a yes or no, and reasonable men reach opposite conclusions on the same evidence.

There is no national screening programme precisely because the balance is close. What shifts it: a family history of prostate cancer, and Black African or Caribbean heritage, both of which raise risk substantially.

Does a raised PSA mean cancer?

No — and most men with a raised PSA do not have it.

Benign enlargement, infection, prostatitis, recent ejaculation and cycling all raise it. A raised result means further assessment, not a diagnosis.

Does a normal PSA mean I am clear?

No. A proportion of significant prostate cancers occur with entirely normal PSA levels.

Symptoms still matter — a normal result is not a reason to ignore a change in urinary pattern, bone pain or weight loss.

What should I avoid before the test?

Ejaculation for 48 hours, and vigorous exercise or cycling for 48 hours — both genuinely raise PSA and produce results that need repeating.

And postpone for at least six weeks after a urinary infection or any prostate procedure.

I take finasteride. Does that matter?

Yes, considerably — and it is missed regularly. Finasteride and dutasteride roughly halve PSA, whether taken for hair loss or for prostate enlargement.

The result must be doubled to be interpreted, so tell any doctor checking it that you take it.

What happens if my PSA is raised?

Not an immediate biopsy. Current UK practice is multiparametric MRI first, which frequently avoids biopsy altogether and targets it better where one is needed.

That is a meaningful improvement on the older pathway, and worth knowing when weighing whether to test.

What does "overdiagnosis" actually mean here?

Finding a cancer that would never have caused you harm. Some prostate cancers grow so slowly that they would never produce symptoms or shorten life.

The difficulty is that once found, they are hard to leave alone — and treatment carries real risks of incontinence and erectile dysfunction. That is the central argument against routine screening, and it deserves stating plainly.

Can you examine my prostate?

No — that requires an in-person examination, which we cannot do. We can arrange the blood test, interpret it, and refer.

Are prostate supplements worth taking?

Saw palmetto and similar products have not shown convincing benefit in good trials for either symptoms or prevention.

Some may also affect PSA readings, which is an unhelpful side effect for a product bought by men worried about their prostate.

I am getting up several times a night. Is that cancer?

Usually benign prostate enlargement, which is common and treatable. Prostate cancer typically causes no urinary symptoms at all until it is advanced.

Worth mentioning: sleep apnoea is a frequently missed cause of getting up at night, and it is not a prostate problem at all.

Questions about our service

How quickly can I be seen?

Same-day access is usually available, from 6am to 10pm, seven days a week. You choose a time that suits you rather than waiting on hold at 8am.

Will I see the same doctor each time?

Yes. Care is led personally by Dr Mohammad Khan, so you are not passed between clinicians. Continuity is the point of a small practice: someone who knows your history and is listening attentively rather than working through a checklist.

Can you see my NHS records?

Yes, with your consent. We can access your Summary Care Record during the consultation, so your current medications, allergies and significant history are in the room. That means fewer questions you have already answered elsewhere, and safer prescribing.

Are you trying to replace my NHS GP?

No. We are not here to replace GPs, only to support them. Your NHS practice remains responsible for your ongoing care, and with your consent we write to them after the consultation. We are useful when you need to be seen sooner, or want more time than a standard appointment allows.

What is included in the appointment?

Twenty unhurried minutes and a comprehensive assessment. A written treatment plan is included, along with any prescription, sick note or referral letter arising from the consultation, at no extra charge.

How much does it cost?

£40 for 20 minutes, self-pay. Membership is optional and never required. Priced for fairness, because we are not here to charge extortionate amounts for access to a doctor.

What does “treatable online” actually mean?

It means the diagnosis can usually be made from your history and photographs, and that treatment can be arranged safely without examining you. Where a condition is not marked treatable online, it is because examination is the diagnosis — listening to a chest, feeling an abdomen, examining an ear or a joint — or because a procedure or device is needed.

Can you prescribe antibiotics?

Yes, where there is a genuine bacterial infection — cellulitis, impetigo, bacterial urine infections, confirmed strep throat. We will also frequently tell you that you do not need one. Most sore throats, coughs, colds and earaches are viral, and an antibiotic gives you the side effects with none of the benefit.

What if the GP cannot help with what I need?

If your problem turns out to be genuinely outside what we can do remotely, the doctor will tell you straight away, point you to the right service, and refund your fee in full. We would rather do that than fill twenty minutes to justify the charge.

What should I do in an emergency?

Call 999 or go to A&E — do not book an online appointment and do not wait for a reply to an email. For urgent problems that are not emergencies, NHS 111 is available 24 hours a day, online or by phone, and can direct you to the right service.
