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 the proportion of unbound, or free, PSA tends to differ between benign prostate changes and prostate cancer, this ratio can add context to a standard total PSA result. It is not a stand-alone diagnostic test, but an additional data point that clinicians may use when interpreting an elevated or borderline total PSA.
About Prostate-Specific Antigen (PSA), Free-to-Total Ratio in St. Cloud
The free-to-total PSA ratio refines the interpretation of total PSA by measuring how much of the antigen circulates unbound.
Prostate-specific antigen is a protein produced by the prostate gland. In the bloodstream, a portion of PSA is bound to other proteins, while the remainder circulates freely. A total PSA test measures both fractions together. The free-to-total ratio is derived by dividing the free PSA value by the total PSA value, usually expressed as a percentage.
The ratio is most often considered when total PSA falls in an intermediate range where the cause is unclear. A lower free-to-total percentage is more frequently associated with prostate cancer, whereas a higher percentage is more typical of benign prostatic conditions such as enlargement or inflammation. No single threshold applies to every patient, and age, prostate size, and other clinical factors influence how the result is read.
This test requires a standard blood draw, typically from a vein in the arm. No special preparation is usually needed beyond following the laboratory's instructions. Results are generally reported within one to three business days. Because the ratio depends on both free and total PSA measurements, the two values are collected from the same blood sample and interpreted together.
