Quick answer
The Prostate-Specific Antigen Free-to-Total Ratio Test measures three related values from a blood sample: total PSA, free PSA, and the ratio of free to total PSA. PSA is a protein produced by the prostate gland, and the ratio can provide additional information when the total PSA is elevated. The test is used by healthcare providers as part of prostate evaluation and is interpreted with other findings such as examination results and the person's history.
What this test measures
Prostate-specific antigen is a protein made by prostate cells, and small amounts are normally present in the blood. Total PSA measures everything detected by the assay, while free PSA measures the portion that is not bound to other proteins. The free-to-total ratio is calculated from those two values and can help characterize an elevated total PSA when a healthcare provider is deciding what evaluation steps may be appropriate.
The test requires only a blood sample, and results are reported as quantitative PSA concentrations along with the calculated percentage of free PSA. Some laboratories also report complexed PSA or age-specific reference ranges. Because PSA can be affected by benign prostate enlargement, inflammation, recent procedures, and other factors, results are never interpreted in isolation.
This test may be ordered after an elevated total PSA result or when a healthcare provider wants more detail during prostate evaluation. It is not a cancer test by itself and cannot confirm or exclude prostate cancer. A qualified healthcare provider should interpret the results and determine whether additional evaluation is needed.
