PSA Free & Total Blood Test - More Information

This PSA total & free test measures the total PSA and free PSA blood levels. This lab test builds on the total PSA test by measuring the free portion of prostate-specific antigen in addition to the total PSA level in the blood.

The free component of this PSA test represents the bioavailable portion of the prostate-specific antigen in the blood. To get from where it is made to tissues it exerts its effects on, most PSA is transported by carrier proteins in the blood while a small percentage of it circulates unbound. And so, when the term bioavailable, or free, is used in the context of PSA levels, it represents prostate-specific antigen that is floating freely. Free PSA provides helpful information when compared to the total PSA levels. PSA free / total ratios of less than 25% are correlated with an increased risk of prostate cancer in men. Because of the additional information the free measurement of PSA provides, PSA total and free levels are frequently measured by people who have a higher risk of prostate cancer.
