About Prostate-Specific Antigen (PSA), Free-to-Total Ratio in Riverview
This test measures the proportion of PSA that circulates unbound in the bloodstream relative to the total amount of PSA present.
Prostate-specific antigen is a protein produced by the prostate gland. In the blood, a portion of PSA is bound to other proteins, while the remainder circulates freely. The free-to-total ratio expresses the free fraction as a percentage of the total PSA concentration.
The ratio is most often ordered when a total PSA result is mildly elevated but not clearly diagnostic. A lower free-to-total percentage is generally associated with a higher likelihood of prostate cancer, whereas a higher percentage is more commonly seen in benign prostate conditions.
Because the ratio depends on accurate measurement of both free and total PSA, the calculation is only as reliable as the underlying assays. Results should always be interpreted by a qualified healthcare professional alongside other clinical findings.
