Order Prostate-Specific Antigen (PSA) Total TestThe Prostate-Specific Antigen (PSA) Total Test measures the amount of prostate-specific antigen circulating in the blood. PSA is a protein produced primarily by the prostate gland, and its total concentration can be quantified through a standard blood draw. This test is used as a tumor marker to support the early detection of prostate cancer and to aid in monitoring other prostate-related conditions.
About Prostate-Specific Antigen (PSA) Total Test in Riverside
Prostate-specific antigen is a glycoprotein enzyme secreted by the epithelial cells of the prostate gland.
PSA is produced by both normal and malignant prostate tissue, which means an elevated total PSA level is not exclusive to cancer. Benign prostatic hyperplasia, prostatitis, urinary tract infections, and recent prostate procedures can all raise total PSA concentrations. Because of this overlap, the test is interpreted alongside clinical history, digital rectal examination findings, and, when appropriate, additional testing such as free PSA or prostate biopsy.
The total PSA test quantifies both free PSA, which circulates unbound, and complexed PSA, which is bound to protease inhibitors in the blood. Results are typically reported in nanograms per milliliter. There is no single universal cutoff that separates benign from malignant findings; reference ranges vary by laboratory and by factors such as age. Clinicians often evaluate the rate of change over time, known as PSA velocity, rather than relying on a single measurement alone.
As a tumor marker, total PSA is most useful when interpreted in context. It can support the early detection of prostate cancer, help assess response to treatment, and assist in detecting recurrence after therapy. However, it is not a definitive diagnostic test on its own. A confirmed diagnosis of prostate cancer requires tissue examination, typically through a prostate biopsy. The total PSA test remains a widely used tool in prostate health assessment when combined with other clinical information.
