About this test
Measures total prostate-specific antigen (PSA), free PSA and the calculated free-to-total PSA ratio to support a clinician-led assessment of prostate health. It cannot diagnose or rule out prostate cancer and should be interpreted with age, symptoms, examination findings and other clinical information.
At a glance

- Collection: Follow the supplied instructions for providing your blood sample
- Estimated turnaround: 1 day from laboratory receipt of a usable sample
What this test measures
- Total prostate-specific antigen (PSA)
- A prostate protein that can be raised for cancerous and non-cancerous reasons. A raised result can occur with prostate cancer, benign enlargement, inflammation or recent prostate stimulation and normally requires clinician-led follow-up.
- Free prostate-specific antigen (free PSA)
- The portion of PSA circulating in an unbound form. A raised result can occur with prostate cancer, benign enlargement, inflammation or recent prostate stimulation and normally requires clinician-led follow-up.
- Free-to-total PSA ratio
- A calculated ratio that may add context to total PSA; it cannot diagnose or rule out prostate cancer. A raised result can occur with prostate cancer, benign enlargement, inflammation or recent prostate stimulation and normally requires clinician-led follow-up.
How clinicians use this test
Clinicians may use Total prostate-specific antigen (PSA), Free prostate-specific antigen (free PSA) and Free-to-total PSA ratio as one part of investigating symptoms, estimating risk or planning follow-up. Tumour and risk markers cannot diagnose or exclude cancer on their own.
Is this the right test for you?
Someone considering this marker after discussing its benefits, limitations and follow-up with a clinician. It is not a substitute for symptom assessment or an NHS screening pathway.
Preparation and collection
Follow the supplied kit instructions. No product-specific preparation requirements are stated publicly. Do not stop prescribed medicines unless a clinician tells you to.
Understanding your result
The most useful information is usually the pattern across Total prostate-specific antigen (PSA), Free prostate-specific antigen (free PSA) and Free-to-total PSA ratio, not one isolated flag. Related markers can support or contradict each other, and a mildly out-of-range value may reflect normal biological variation, collection conditions or temporary illness rather than disease.
Your results and next steps
Share any raised, positive or unexpected result with your GP or the clinician who advised testing. Further assessment may include examination, imaging or another test.
Limitations
This test cannot diagnose or rule out cancer by itself. False-positive and false-negative results are possible, and symptoms require assessment regardless of the result.
When to get medical help
Do not wait for a home-test result if you feel seriously unwell. Call 999 for a life-threatening emergency, or use NHS 111 when you need urgent advice and are unsure what to do.

Questions, answered
How accurate is an at-home test?
Your sample is processed by a professional UK partner laboratory using the same analytical methods used for clinician-requested testing. Sample quality depends on following the collection instructions carefully.
Are my results private?
Yes. Kits use discreet packaging and your results are delivered through a secure digital service.
Does this diagnose a condition?
No. The test checks and measures biomarkers. Results and the doctor’s comment can help you decide what to discuss with your GP.
When should I post my sample?
Collect and post on the same day, ideally Monday–Thursday, to avoid a sample waiting in the postal system over a weekend.
What happens if my sample cannot be processed?
The support team will explain the next step if the laboratory cannot process your sample. Any recollection or refund depends on the circumstances and the applicable policy.
When should I speak to my GP?
Speak to your GP if symptoms persist, worsen or concern you. Seek urgent medical help for severe or sudden symptoms.
