PSA is a protein produced primarily by the prostate gland, and its total concentration is used as a tumor marker in the evaluation of prostate health.
About Prostate-Specific Antigen (PSA) Total Test in Norwalk
PSA is a glycoprotein enzyme produced by the epithelial cells of the prostate gland. Its primary biological role is to liquefy semen, but it is also released into the bloodstream in small quantities. Measuring total PSA provides a single numerical value that reflects the combined contribution of both free and protein-bound forms of the antigen.
The test is typically ordered to screen for or monitor prostate cancer, as elevated total PSA levels can indicate the presence of malignancy. However, PSA is not specific to cancer; benign conditions such as benign prostatic hyperplasia, prostatitis, and urinary tract infections can also raise total PSA.
Because total PSA alone does not distinguish between benign and malignant causes, results are often interpreted alongside other clinical findings. Some clinicians use additional calculations, such as PSA density or age-specific reference ranges, to refine risk assessment.
The test requires a simple blood draw, and the sample is analyzed in a laboratory to determine the total PSA concentration. Turnaround time is generally one to three business days, and preparation should follow the lab's instructions.
