PSA, Free:Total Ratio
Sample Report
Specimen Type: Blood


Prostate Specific Antigen Free: Total Ratio Test

The Prostate Specific Antigen (PSA) Free:Total Ratio provides several measurements which help to screen for prostate cancer. This test includes measurements for PSA, Free PSA and % Free PSA. PSA is a protein produced by the prostate gland. Elevated PSA levels may indicate a higher likelihood of having prostate cancer. However, not all cases of prostate cancer will cause elevated PSA levels and there are conditions other than cancer which may cause elevated PSA.

Free PSA is the portion of PSA which is not bound to other proteins in the blood. Generally, men with lower levels of Free PSA have a higher likelihood of having Prostate Cancer. Free PSA measurements are useful for people with borderline or moderately increased total PSA levels. A test which includes Free PSA is often ordered as a follow up to a high PSA test.

The turnaround for this test is typically 1-3 business days.

Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.


The PSA, Free:Total Ratio test has no special requirements.
