What you need to know about our PSA Blood Test (Prostate Specific Antigen)

Prostate cancer often doesn't cause any symptoms and the commonest way to pick it up is actually following a PSA blood test.

Regular PSA testing has been shown to pick up more cases of prostate cancer, increases your chances of picking up prostate cancer before it has spread and reduces the chance of dying from prostate cancer by about 30%ref.

Guidelines support PSA testing from age 45 to understand your baseline risk of prostate cancer and to guide how regularly you should consider testing. Men at higher risk - of black ethnic origin or with a family history of prostate cancer for example - should start testing earlier, from age 40.

PSA testing is the first, crucial step in the pathway of prostate cancer diagnosis and management and taking it puts you firmly in the driving seat.

What do the PSA test results mean?

Your PSA level needs to be interpreted in the context of your age because PSA naturally goes up as you get older due to the prostate increasing in size. The National Institute of Clinical Excellence (NICE) have suggested PSA thresholds for specific ages to trigger further investigation of the prostate (e.g. with an MRI scan).

AgePSA Threshold (μg/L)
40 - 49>2.5
50 - 69>3
70 and over>5

However, other guidelines recommend that all men with a PSA above 3μg/L undergo further investigations. We suggest that anyone with a PSA level over 3μg/L discuss this with their doctor.

A high PSA level doesn't mean you have prostate cancer but it does make prostate cancer more likely and you'll generally be advised to have a scan of the prostate to investigate further.

How accurate is a PSA test?

Remember that the PSA test is not meant to be a test to identify prostate cancer. It is a test to assess your risk of having prostate cancer. Your risk of prostate cancer will depend on how high your PSA level is.

  • If your PSA level is between 3 - 10 μg/L, your risk of prostate cancer is about 25%.
  • If your PSA level is over 10 μg/L, your risk of prostate cancer is over 50%.

However, it's important to bear in mind that about 1 in 7 men can have a normal PSA level and later be diagnosed with prostate cancer. This is why it's so important for men to monitor their PSA level regularly rather than just as a one-off.

5α-reductase inhibitors can falsely lower PSA levels so you need to adjust your result (doubling your PSA) if you take this medication.

What's tested in the PSA Blood Test (Prostate Specific Antigen)?

Our PSA test checks for prostate specific antigen levels in your blood. High PSA levels can be a sign of prostate cancer and should be followed up with a prostate scan.

In addition to testing your PSA level, we'll also test your free PSA level and Free-to-Total PSA ratio if your PSA level is borderline high, at no extra cost. These markers give you more information on your prostate cancer risk.
