Prostate Specific Antigen (PSA)

About Test

The Prostate-Specific Antigen (PSA) test measures the level of PSA, a protein produced by the prostate gland, in the blood. PSA is naturally present in low levels in the blood, but elevated levels can indicate prostate issues, including benign conditions like prostatitis (inflammation of the prostate) and benign prostatic hyperplasia (enlargement of the prostate), as well as prostate cancer.

The PSA test is commonly used as a screening tool for prostate cancer, particularly in men over the age of 50 or those with a family history of the disease. It can also be used to monitor the progression of prostate cancer in patients who have already been diagnosed and to evaluate the effectiveness of treatment.

While elevated PSA levels can suggest the presence of prostate problems, it is important to note that other factors, such as age, race, and certain medications, can also affect PSA levels. Therefore, the PSA test is often used in conjunction with other diagnostic tools and evaluations to provide a comprehensive assessment of prostate health. Regular monitoring and appropriate follow-up are crucial for managing prostate conditions effectively and ensuring overall well-being.
