About Prostate-Specific Antigen (PSA), Free-to-Total Ratio in Raytown
This test measures the proportion of prostate-specific antigen that circulates unbound in the bloodstream relative to the total PSA concentration.
Prostate-specific antigen is a protein produced primarily by the prostate gland. In the bloodstream, a portion of PSA exists in a free, unbound state, while the remainder is complexed with other proteins. The free-to-total ratio expresses the free fraction as a percentage of the total PSA value.
Clinicians sometimes use this ratio when a total PSA result falls in an intermediate range where the likelihood of prostate cancer is uncertain. A lower free-to-total percentage can be associated with a higher probability of malignancy, whereas a higher percentage is more often seen in benign prostate conditions. The ratio is interpreted alongside other clinical findings rather than as a stand-alone diagnosis.
The test requires a blood sample, typically collected from a vein in the arm. No special preparation beyond following the laboratory's instructions is generally needed, though some clinicians may advise avoiding certain activities before collection. Results are usually reported within one to three business days.
