Order Prostate-Specific Antigen (PSA), Free-to-Total RatioProstate-specific antigen (PSA) is a protein produced by the prostate gland, and it circulates in the blood in both bound and unbound forms. The free-to-total ratio compares the unbound portion of PSA to the overall PSA concentration, offering a more detailed view than the total PSA value alone.
About Prostate-Specific Antigen (PSA), Free-to-Total Ratio in Encinitas
The free-to-total PSA ratio is a calculated value derived from two measurements: free PSA and total PSA.
Total PSA includes all PSA in the blood, whether attached to other proteins or circulating freely. Free PSA refers only to the unbound fraction. The ratio expresses free PSA as a percentage of total PSA.
Because benign prostate conditions and prostate cancer can both raise total PSA, the ratio can help clarify ambiguous results. A lower free-to-total ratio is generally associated with a higher likelihood of prostate cancer, while a higher ratio is more often seen with benign enlargement.
This test is typically ordered when total PSA is mildly elevated and the clinical picture is unclear. It is not a stand-alone diagnostic tool; results are interpreted alongside digital rectal examination, imaging, and, when indicated, biopsy findings.
