Order Prostate-Specific Antigen (PSA), Free-to-Total RatioThe free-to-total prostate-specific antigen ratio is a calculated value derived from two measurements of the same blood sample. It refines the information provided by total PSA alone by describing how much of the circulating antigen is unbound to proteins in the bloodstream.
About Prostate-Specific Antigen (PSA), Free-to-Total Ratio in St. Augustine
The free-to-total PSA ratio compares the unbound fraction of prostate-specific antigen with the total amount present in the sample.
Prostate-specific antigen is a protein produced by the prostate gland and released into the bloodstream. In circulation, a portion of it binds to carrier proteins while the remainder circulates freely. A total PSA measurement captures both fractions together, whereas the free-to-total ratio expresses the unbound portion as a proportion of the whole.
The ratio is calculated by dividing the free PSA concentration by the total PSA concentration, typically reported as a percentage. Because the two values come from a single specimen, the calculation does not require a separate collection. Laboratories may apply different assay methods, so results are generally interpreted against the reference range established by the performing laboratory.
This ratio is most often interpreted alongside total PSA rather than in isolation. Clinicians may use it to add context when total PSA falls in an intermediate range, since the proportion of free PSA can differ between benign and malignant prostate conditions. It is not a stand-alone diagnostic test, and results are considered together with other clinical findings.
