How to Book a Private PSA Blood Test: Cost, Who It Suits and What Happens Next

You can book a private PSA blood test with Swift for £50. It’s a single PSA marker, taken from a vein by a trained phlebotomist at a clinic, or at home on a home visit.

Before you book, it’s worth knowing what PSA can and can’t tell you. The UK doesn’t run a screening programme for prostate cancer, because the PSA test is useful but imperfect.

PSA test cost and price in the UK

A private PSA test in the UK usually costs between about £37 and £85, depending on the provider and whether you use a postal kit or a venous sample. Postal finger-prick kits are often cheaper but can fail if the sample is too small. Swift’s £50 price covers a venous blood draw at a clinic, and home visits are available for an additional fee. On the NHS, the PSA test is free for men aged 50 and over who ask their GP after discussing the pros and cons.

What PSA is

PSA (prostate-specific antigen) is a protein made by the prostate gland. A small amount normally passes into the blood. Levels can rise with prostate cancer, but also with an enlarged prostate, a prostate infection and some everyday activities. That’s why a raised result is a reason for further checks, not a diagnosis.

Who should consider a PSA test

• The NHS position: any man aged 50 or over can ask his GP for a free PSA test after talking through the pros and cons.
• Higher risk: Prostate Cancer UK recommends talking to your GP from age 45 if you’re Black, or if your father or brother had prostate cancer.
• Symptoms: needing to pee more often, a weak flow, urgency or blood in your pee mean you should see your GP rather than just booking a test.

The honest pros and cons

The test has real benefits. It can pick up prostate cancer before symptoms appear, when treatment is more likely to work. It also has clear limits:

• False positives. About 3 in 4 men with a raised PSA level won’t have cancer. Infection, an enlarged prostate, recent ejaculation or vigorous exercise can all raise PSA.
• False negatives. Prostate Cancer UK cites research showing that about 1 in 7 men with a normal PSA level may still have prostate cancer.
• Overdiagnosis. The test can find slow-growing cancers that would never have caused harm, which can lead to treatment that wasn’t needed.
• Medicines. Finasteride and dutasteride lower PSA. Tell the clinician if you take them, and don’t stop them.

How to prepare

A few steps help avoid a falsely raised result:

• Avoid ejaculation for 48 hours before the test.
• Avoid vigorous exercise, especially cycling, for 48 hours before.
• If you have a urine infection, wait until it has cleared before testing.
• You don’t need to fast for a PSA test.

Private test or GP?

	GP	Swift
Cost	Free for men aged 50 and over	£50
Access	An appointment and discussion first	Book online, at a clinic or at home
If the result is raised	GP-led pathway, often an MRI scan before any biopsy	Share your result with your GP to start the NHS pathway

Many men book privately for convenience, or because they’re under 50 and want a baseline after a family member’s diagnosis.

What happens after a raised result

One raised result isn’t a diagnosis. Your GP may:

1. repeat the PSA test after a few weeks;
2. examine your prostate;
3. check for a urine infection;
4. refer you for an MRI scan if the result stays raised.

PSA results are interpreted using age-related thresholds, because levels naturally rise with age. Our blood test results guide explains how results are reported.

Booking

View the PSA test, then choose a clinic in Billericay, Basildon, Thurrock, Maldon, Brentwood, Chelmsford, Bromley or Sunbury, or a home visit across Essex, Bromley and Surrey. Use the clinic finder to find your nearest location. If you’d like a wider check-up at the same time, see the Men’s Health MOT.

Repeat testing

If your first result is normal, there’s no fixed rule for how often to retest. Many men who choose to monitor PSA repeat it every one to two years, and some GPs suggest a longer gap for lower results. Testing at the same laboratory and following the same preparation each time makes changes easier to spot. A steady rise over time can matter more than a single number, so keep a record of every result.
