The PSA (Free) Test measures the levels of unbound or free PSA in blood.

PSA is a protein which is secreted by the prostate gland. The prostate gland is a male accessory reproductive organ, the secretion of which contributes to the formation of the seminal fluid. Most of the PSA produced is secreted in the seminal fluid along with other prostatic secretions and only a small amount is secreted into the bloodstream. PSA is considered to be a tumor marker since its levels in the blood are elevated in prostate cancer and BPH, and it is used as a preliminary screening test before further diagnostic procedures.

PSA in blood is found as either complexed PSA (bound to other proteins) or free PSA. The PSA Test usually calculates the total PSA levels in the blood including both free and complexed forms, whereas the PSA (Free) test measures the levels of unbound or free PSA in blood.

Some doctors prefer to measure free PSA in patients with a total PSA level between 4 ng/ml and 10 ng/ml rather than subjecting everyone with an elevated PSA to a biopsy as it is an invasive procedure.
