Jeremy Clarkson has not publicly named the exact test or clinic behind his prostate cancer diagnosis. What he has said is that his cancer was caught early, that he is now in remission, and that checking your prostate "is just a blood test these days." That blood test is almost certainly the PSA test, the most common first-line prostate cancer test doctors use to look for early signs of the disease. Below we explain what a PSA test measures, where it can be misleading, and how the main prostate cancer test options at Goodbody Clinic compare, so you can work out which one fits your situation.

What did Jeremy Clarkson say about prostate cancer?

In June 2026 Jeremy Clarkson revealed he is in remission from prostate cancer, having been diagnosed with an aggressive form of the disease in May 2025. He shared the news as the latest series of Clarkson's Farm aired, and in a video message he reassured fans: "I'm perfectly fine." The reason he is fine, he explained, is that "the doctors caught the prostate cancer early."

His central message was a call to action for men. Clarkson pointed out that around "10,000, 12,000 people, men, to be honest, men, die every year in the UK from prostate cancer," and urged others to get checked the way he did, adding that these days it is "just a blood test." It is a powerful reminder, because prostate cancer rarely causes symptoms in its early stages, which is exactly when it is most treatable.

The numbers back him up. In the UK, around 1 in 8 men will be diagnosed with prostate cancer in their lifetime, and the risk rises with age. Catching it before it spreads makes an enormous difference to outcomes.

What is a PSA test and how does it work?

A PSA test is a blood test that measures the level of prostate specific antigen (PSA), a protein made by both healthy and cancerous prostate cells, in your blood. It is normal to have a small amount of PSA, and the level tends to rise gently as you get older and your prostate grows. A higher than expected reading can be an early flag worth investigating.

Here is the honest part, and it matters. A raised PSA does not mean you have cancer. It can also be caused by a urine infection, an enlarged prostate, recent vigorous exercise, or recent ejaculation. In fact, around 3 in 4 men with a raised PSA turn out not to have prostate cancer, and the PSA test on its own has an accuracy of roughly 55 percent. This is why the NHS does not run a national screening programme based on PSA alone, and why a raised result is a prompt to investigate further, not a diagnosis. If your level comes back high, the sensible next step is to speak to your GP and often to repeat the test after 6 to 8 weeks.

Which prostate cancer test is right for you?

Because the standard PSA test is a useful but blunt tool, more advanced prostate cancer tests have been developed to add accuracy and to focus on the aggressive cancers that matter most. Goodbody Clinic offers four blood test options, from a quick first check to comprehensive screening. Here is how they compare.

If you simply want to do what Clarkson described, a straightforward PSA blood test is the place to start. If you are higher risk or want a clearer picture of whether a raised PSA is something to worry about, the more advanced tests earn their place.

The Stockholm3 test was designed to catch aggressive prostate cancer early while reducing unnecessary biopsies. It combines your PSA with genetic and biological markers plus clinical data to produce a single risk score, which can give real peace of mind to men who fall into a grey area.

For the most accurate read after a raised PSA, the EpiSwitch PSE test reports an accuracy of 94 percent in detecting prostate cancer, compared with around 55 percent for PSA alone. It blends five immune markers in your blood with a recent PSA result, which can help you avoid an invasive biopsy you may not need.

And if your prostate is just one part of a wider men's health check, the Signature Well Man test covers 67 biomarkers, including PSA, alongside hormones, cholesterol, liver and kidney function and more. It is a thorough way to take stock of your health in one appointment.

What are the early symptoms of prostate cancer?

Here is the catch that makes testing so important: in its early stages, prostate cancer usually has no symptoms at all. That is exactly why Jeremy Clarkson's cancer was found through a blood test rather than because he felt unwell. When prostate cancer symptoms do appear, they often mean the prostate has grown large enough to press on the tube that carries urine. Signs to look out for include:

• Needing to pee more often, especially at night
• Difficulty starting, or a weak or stop-start flow
• A feeling that your bladder has not fully emptied
• Blood in your urine or semen

Most of these symptoms are caused by a non-cancerous enlarged prostate rather than cancer, but they are always worth getting checked. The key point is that because early prostate cancer is silent, a prostate cancer test is the only reliable way to catch it before symptoms ever start.

Who should consider a prostate cancer test?

Prostate cancer mainly affects older men, which is why testing matters even when you feel completely well. Current NHS guidance is that men aged 50 and over can ask their GP about a PSA test after weighing up the pros and cons. Some men are at higher risk and may want to start the conversation earlier, from around age 45. That includes:

• Black men, who have roughly double the lifetime risk.
• Men with a family history of prostate cancer, especially a father or brother.
• Men noticing changes to how they pee, blood in their urine, or erectile difficulties, although these are more often caused by non-cancerous conditions.

Whatever your age, the value of a blood test is information. As Goodbody's tagline puts it, the goal is to know more so you can live better. A test will not always give a clear yes or no, but it gives you and your doctor a starting point. For background on national guidance, Cancer Research UK has a clear overview, and you can book a prostate cancer test with Goodbody whenever you are ready.

Frequently asked questions

Which blood test did Jeremy Clarkson use?

Clarkson has not publicly named the specific test or clinic. He described his check as "just a blood test," which points to the standard PSA test that doctors use as a first step to look for signs of prostate cancer.

Is a PSA test accurate?

On its own, the PSA test is a useful but imperfect tool, with an accuracy of around 55 percent, and about 3 in 4 men with a raised PSA do not have cancer. A high result is a reason to investigate further, not a diagnosis. More advanced blood tests such as Stockholm3 and EpiSwitch PSE were created to improve on this.

Can I do a prostate cancer blood test at home?

Yes. The Goodbody Prostate PSA Blood Test is available as a home finger-prick kit from £69, or you can have blood taken by a professional in a clinic or at home by a nurse. Results follow in 3 to 5 working days.

At what age should I get a PSA test?

Men aged 50 and over can ask their GP about a PSA test. If you are Black or have a family history of prostate cancer, it is worth starting that conversation from around age 45.

Does a high PSA always mean cancer?

No. A raised PSA can be caused by an enlarged prostate, a urine infection, recent exercise or recent ejaculation. If your level is high, the usual advice is to speak to your GP and often to repeat the test after 6 to 8 weeks.
