What does PSA mean?
PSA is a protein made mainly by prostate tissue. A changing result can guide further discussion about prostate enlargement, inflammation and cancer risk in the right clinical context.
What it shows and why it matters
PSA, or Prostate-Specific Antigen, is a protein made mainly by prostate tissue. A raised or changing result can occur with prostate enlargement, inflammation, recent prostate stimulation or cancer, so the pattern can guide further discussion and investigation with a doctor. PSA is age- and context-dependent and is not a stand-alone population screening result.
How PSA appears on your report
Look for Prostate-Specific Antigen (PSA). The result is normally shown in µg/L, next to the reference interval used by the laboratory that ran the test.
Note the collection date before you compare it with anything, along with the context that matters for this marker: age, prostate enlargement, prostatitis, urinary infection, ejaculation, cycling, prostate procedures and some medicines can affect it. Method and previous trend matter.
PSA range in Australia
Vector shows an assay-dependent contextual tracking band of 0.0–4.0 µg/L for PSA. It is not a universal optimal target or clinical threshold; use the interval printed by the laboratory that performed the test.
This contextual band mirrors the app and the Vector Profile; the performing laboratory’s interval remains authoritative.
Interpretation limits
PSA is not a stand-alone cancer screening or diagnostic result. Age, method, symptoms, examination, benign prostate conditions and the previous trend all change what a value means.
The interval printed beside your result remains the authority for that specimen. Reference intervals, diagnostic thresholds, treatment targets and Vector's tracking bands answer different questions and should not be substituted for one another.
What to read alongside PSA
A single marker rarely explains itself. These results are commonly interpreted together with PSA, and Vector keeps them within reach of each other as your record grows.
When to discuss PSA with a clinician
Discuss a raised or changing PSA with your GP using the laboratory interval, your age, symptoms and previous results. Australian guidance determines whether repeat testing, examination or referral is appropriate.
Tracking PSA over time
One PSA result is a single point. Import the report into Vector, check the extracted value, unit and collection date, and it becomes the start of a series instead — with each later report adding a dated point you can actually compare against.

PSA is read the same way every other result on the report is. These two guides cover that method rather than this marker:

Common questions
What is a normal PSA range in Australia?
Australia has no nationally harmonised reference interval for PSA, so the range printed on your report varies with the laboratory and assay. Vector shows 0.0–4.0 µg/L as an assay-dependent contextual tracking band, not a universal optimal target or clinical threshold. Always use the interval beside your own result.
How should the PSA tracking band be interpreted?
Vector shows 0.0–4.0 µg/L as an assay-dependent contextual band for PSA. It is not a universal optimal target or clinical threshold. Interpret the result with the performing laboratory's interval, treatment and symptoms.
What unit is PSA reported in on Australian pathology reports?
PSA is usually reported in µg/L on Australian pathology reports. The performing laboratory prints a reference interval in the same unit beside the result, and that interval is the one that governs your individual result.
What can change your PSA result?
Age, prostate enlargement, prostatitis, urinary infection, ejaculation, cycling, prostate procedures and some medicines can affect it. Method and previous trend matter.
