Overview of the Prostate PSA Profile
The Prostate PSA Profile measures Total PSA, Free PSA and the Free-to-Total PSA Ratio to provide more information than Total PSA alone.
The test contains 3 biomarkers.
PSA is a protein produced by prostate tissue. Small amounts normally circulate in blood.
PSA can increase because of benign prostate enlargement, prostatitis, urinary infection, recent prostate manipulation and prostate cancer.
This means an elevated Total PSA is not a diagnosis of prostate cancer.
Free PSA measures the fraction circulating without being bound to proteins.
In selected men with an intermediate Total PSA concentration, the proportion that is free can provide additional risk information.
A lower Free-to-Total PSA Ratio can be associated with a greater probability of prostate cancer, whereas higher proportions are more commonly seen with benign prostate enlargement. There is substantial overlap, however, and no ratio can confirm or exclude cancer.
PSA should therefore be interpreted alongside age, symptoms, family history, previous PSA trend, medication and, where clinically appropriate, prostate examination or MRI.
What Does the Prostate PSA Profile Check?
This test measures 3 biomarkers.
Total Prostate Specific Antigen
Measures the total concentration of PSA circulating in the blood.
Free Prostate Specific Antigen
Measures the unbound fraction of circulating PSA.
Free : Total PSA Ratio
Calculates the proportion of Total PSA that is present in the free form and can provide additional risk information in selected clinical circumstances.
Who May Benefit From the Prostate PSA Profile?
This profile may be useful when a man wants more detailed PSA assessment than Total PSA alone, particularly where a previous result is borderline, elevated or requires follow-up.
Men with a previous borderline Total PSA - Free PSA and the ratio can add information to the overall risk assessment.
Men with a persistently raised PSA result - Repeat testing can establish the trend and provide additional context.
Men with a strong family history of prostate cancer - Familial risk can make earlier or closer assessment appropriate.
Men with lower urinary tract symptoms - Prostate enlargement and inflammation can affect both urinary symptoms and PSA.
Men undergoing urological follow-up - A specialist may request Free PSA or the ratio as part of ongoing assessment.
Men considering PSA testing after an informed discussion - Understanding the benefits and limitations of PSA testing is important.
Men monitoring a previous prostate abnormality - Serial PSA measurements can provide useful information about change over time.
How to Prepare
Do not stop prescribed prostate medication simply to obtain a different PSA result.
Recent infection or prostate manipulation can significantly influence PSA and may make postponing routine testing more appropriate.
Symptoms and Reasons to Consider the Prostate PSA Profile Test
Prostate conditions can cause urinary symptoms, although early prostate cancer may produce no symptoms at all.
Difficulty starting urination - Urinary obstruction can occur with benign prostate enlargement and other prostate conditions.
A weak urinary stream - Reduced flow may result from prostate enlargement.
Needing to urinate more frequently - Lower urinary tract symptoms become more common as the prostate enlarges.
Frequent urination at night - Nocturia can occur with benign prostate enlargement and other urinary conditions.
Feeling that the bladder has not emptied fully - This can occur when urinary flow is obstructed.
A previous elevated PSA - More detailed PSA assessment may provide additional context.
No symptoms but a strong family history of prostate cancer - Prostate cancer can be asymptomatic in its earlier stages.
A persistently changing PSA trend - Changes over time may warrant further assessment even when symptoms are absent.
Urinary symptoms are more commonly caused by benign prostate enlargement than by prostate cancer.
Inability to pass urine, significant blood in the urine, severe urinary pain or fever with suspected prostatitis requires prompt clinical assessment.

Select your sample collection option
Choose an in-clinic blood draw or professional home or hotel phlebotomy depending on location and availability.
Attend your appointment
A trained healthcare professional collects the required venous blood sample.
Laboratory analysis
Total PSA and Free PSA are measured and the Free : Total PSA Ratio is calculated.
Receive your results securely
Your authorised prostate report is delivered securely and can be reviewed with a GP or urologist where appropriate.
When Will I Receive My Results?
The expected turnaround time for the Atypical Pneumonia Screen is approximately 7 business days.
Results are sent securely by email once specialist laboratory analysis and authorisation are complete. Turnaround generally begins when the laboratory receives your blood sample rather than necessarily from the time it is collected.
Specialist serology can occasionally require repeat analysis, confirmatory review or additional laboratory processing, which may extend the expected turnaround.
Understanding Your Results
The three results should be interpreted together, alongside age, symptoms and previous PSA history.
A lower Total PSA is generally reassuring but does not completely exclude prostate cancer.
A raised Total PSA can occur with cancer but also with benign prostate enlargement, prostatitis, infection and recent prostate manipulation.
Free PSA and the Free : Total PSA Ratio can provide additional information where Total PSA falls into an intermediate range.
A lower proportion of Free PSA may be associated with a greater probability of prostate malignancy, while a higher percentage is more commonly associated with benign prostate disease.
There is no single PSA concentration or Free PSA ratio that definitively diagnoses cancer.
Persistently abnormal results can lead to repeat PSA testing, GP or urology review, prostate examination or MRI depending on the clinical circumstances.
