The short answer

A high PSA result does not by itself mean prostate cancer. Other prostate conditions can raise it, and testing has benefits and limitations. Discuss whether testing is appropriate and what any result means with your GP or the clinician arranging it.

What is PSA?

PSA stands for prostate-specific antigen. A PSA blood test measures this marker and can help investigate prostate conditions. It is one part of an assessment, rather than a stand-alone cancer diagnosis. NHS guidance recommends discussing the benefits and risks with a GP when deciding whether to have a test.

Why a higher result needs explaining

The NHS notes that a high PSA can occur for reasons other than cancer, including an enlarged prostate. Further assessment may be needed, sometimes beginning with another test. The correct next step depends on your history and the clinical assessment; a number alone does not decide it.

A home indicator and a laboratory measurement

The proposed SHIFT range describes both a rapid prostate-health self-test and a laboratory PSA option. Check the actual method and output on the product page. Do not treat a threshold indicator as though it were a complete laboratory result, or assume a private kit includes a consultation.

Preparation is part of a useful test

Read the current instructions and ask the clinician what applies to your test. NHS PSA guidance explains that factors including a urinary infection and some recent activities can affect the result. Do not guess a preparation rule from a different blood test.

Useful questions for the appointment

Why might PSA testing help in my circumstances? What are the possible downsides of testing? How will the result be interpreted? Who will contact me, and when? If further assessment is needed, who arranges it? These questions are useful whether you are using an NHS or private route.

If you are concerned about symptoms

Tell your GP about urinary changes, blood in your urine or other new concerns; do not wait for a kit to become available. A home result should not become a reason to put off that conversation. The purpose of information is to make the assessment easier to understand, not to replace it.
