Serum Psa

Serum Prostate Specific Antigen (PSA) is a protein produced by the prostate gland in men. It is used as a marker in the diagnosis and monitoring of prostate cancer, as well as in other diseases of the prostate. Increased PSA levels may indicate the presence of cancer, while low levels can help rule out the disease. Serum PSA testing can also be used to monitor the effectiveness of treatments, such as prostatectomy, and to help identify if the cancer has returned after treatment. PSA testing is an important tool in the diagnosis and management of prostate cancer, which can be a life-threatening condition if not detected and treated early.
