Order Prostate-Specific Antigen (PSA), Free-to-Total RatioThe free-to-total PSA ratio is a laboratory calculation that compares two forms of prostate-specific antigen in the blood. Because a portion of PSA circulates unbound, measuring both the free and total fractions can add context to a total PSA result, particularly when the total value sits in an ambiguous range.
About Prostate-Specific Antigen (PSA), Free-to-Total Ratio in Wheeling
This test divides the free PSA concentration by the total PSA concentration to produce a percentage.
Prostate-specific antigen is a protein produced by the prostate gland. In circulation, some PSA is bound to other proteins while the remainder circulates freely. A total PSA measurement captures both fractions together, whereas the free-to-total ratio isolates the unbound portion and expresses it as a proportion of the whole.
The ratio is most often used as a secondary consideration when a total PSA result is mildly elevated but not clearly abnormal. A lower free-to-total percentage is generally associated with a higher likelihood that an elevated total PSA reflects prostate cancer, while a higher percentage is more often seen with benign prostate enlargement or inflammation. The ratio is not a stand-alone diagnostic test and is interpreted alongside the total PSA value, digital rectal examination findings, and other clinical information.
Specimen collection involves a standard blood draw from a vein in the arm. No special diet is required, though the lab's instructions should be followed. Because PSA levels can fluctuate, clinicians may consider recent ejaculation, prostate procedures, or urinary infection when interpreting results. Reporting typically occurs within one to three business days.
