Order Prostate-Specific Antigen (PSA), Free-to-Total RatioThe free-to-total prostate-specific antigen ratio is a laboratory calculation that compares two forms of PSA in the blood. Because total PSA alone cannot distinguish between benign and malignant causes of elevation, the ratio offers additional context for interpreting a result.
About Prostate-Specific Antigen (PSA), Free-to-Total Ratio in Berkeley
The free-to-total PSA ratio measures the proportion of PSA circulating unbound to proteins relative to the total amount present.
Prostate-specific antigen is a protein produced primarily by the prostate gland. In the bloodstream, a portion of PSA circulates freely while the remainder is bound to protease inhibitors. The free-to-total ratio expresses the free fraction as a percentage of the total PSA concentration.
The ratio is typically calculated alongside a total PSA measurement rather than as a standalone test. A lower free-to-total percentage has been associated with a higher likelihood of prostate cancer in some clinical contexts, while a higher percentage is more often seen with benign prostate enlargement. The ratio is not a diagnostic test on its own and is interpreted alongside other findings.
Specimen collection requires a blood draw, usually from a vein in the arm. The laboratory then measures both free and total PSA and reports the calculated ratio. Results are generally available within one to three business days, depending on the laboratory's workflow.
