Order Prostate-Specific Antigen (PSA), Free-to-Total RatioThe free-to-total PSA ratio is a calculated value derived from two measurements of prostate-specific antigen in the blood. It compares the unbound, or free, fraction of PSA to the total amount of PSA present. Because the ratio is a proportion rather than a standalone measurement, it is interpreted alongside the total PSA result and the broader clinical picture.
About Prostate-Specific Antigen (PSA), Free-to-Total Ratio in Carmichael
This test reports the proportion of PSA circulating in an unbound form relative to total PSA.
Prostate-specific antigen is a protein produced by the prostate gland. In blood, a portion of PSA circulates freely while the remainder is bound to other proteins. The total PSA test measures both fractions together, and the free PSA test measures only the unbound portion.
The free-to-total ratio is obtained by dividing the free PSA value by the total PSA value, usually expressed as a percentage. Laboratories may report this percentage directly or provide the two component values so the ratio can be calculated.
The ratio is used as one piece of information among several when a total PSA result is elevated. It does not diagnose any condition on its own, and results are interpreted by a clinician in the context of other findings, including prostate examination and history.
