Order Prostate-Specific Antigen (PSA), Free-to-Total RatioThe free-to-total prostate-specific antigen (PSA) ratio is a laboratory calculation that compares the unbound, or free, portion of PSA in the blood with the total amount of PSA present. Because PSA exists in several molecular forms, separating the free fraction from the total can add a layer of detail that a total PSA measurement alone does not provide. This test is typically ordered when a total PSA result falls in an intermediate range and a clinician wants additional context before deciding on further evaluation.
About Prostate-Specific Antigen (PSA), Free-to-Total Ratio in Uniondale
The free-to-total PSA ratio refines the information supplied by a standard total PSA measurement.
PSA is a protein produced by the prostate gland and released into the bloodstream. In circulation, a portion of PSA binds to other proteins while the remainder circulates unbound, referred to as free PSA. The free-to-total ratio expresses the free fraction as a percentage of the total PSA concentration.
A lower free-to-total ratio has been associated with a higher likelihood of prostate cancer in some clinical settings, whereas a higher ratio is more often seen in benign prostate conditions such as enlargement or inflammation. The ratio is not a stand-alone diagnostic result; it is interpreted alongside the total PSA value, the prostate examination, and other clinical findings.
The test requires a blood sample drawn from a vein, usually in the arm. No special dietary restrictions are generally required, though the laboratory's instructions should be followed. Because PSA levels can fluctuate, clinicians may consider factors such as recent prostate manipulation, ejaculation, or urinary infection when interpreting results. Results are typically reported within one to three business days.
