Understanding the test
What does the Free PSA test measure?
Also called Free PSA
A free PSA result can add information when total PSA is raised and a clinician is weighing further assessment. It is usually interpreted as a proportion of total PSA.
When it may be requested
Clarifying a total PSA value
When appropriate, the free fraction can help interpret a borderline total PSA result.
Considering other factors
The clinician can assess the fraction with age, prostate findings and previous tests.

SpecimenSerum
Your checklist
Avoid ejaculation and vigorous cycling or horse riding for about 48 hours before a planned draw. Tell the team about urinary infection, prostate examination, procedures and prostate medicines so the clinician can choose the timing.
A clinician takes a small sample of blood from a vein. The laboratory uses serum, the liquid separated from the blood after it clots.

Reading your result
A lower or higher proportion can shift an assessment of risk. It cannot establish whether cancer is present.
What can affect it
- Free PSA alone cannot diagnose prostate cancer and should be read with total PSA.

Patient questions
Before you book
Is free PSA meaningful without a total PSA result?
The free-to-total relationship is usually the reason for measuring it. Your clinician needs a suitable total measurement and your prostate history to interpret the result.
Does a low free PSA share mean I have prostate cancer?
A lower free-to-total PSA percentage can increase concern, but the percentage cannot diagnose cancer. Your urologist considers your history, examination and imaging when deciding whether a biopsy would help. A negative biopsy lowers the risk and the urologist can advise whether follow-up is still needed.
Can a urinary infection or prostatitis affect free PSA?
Yes. Prostatitis and urinary infections involving the prostate lift both the free and the total measurement, which can make the result hard to read. Tell the laboratory about any recent urinary infection, and your doctor may prefer to wait until it has settled before relying on the figures.
