PSA Test Kit

BackDuration: 10 minutes

Screen for prostate cancer

Clinical significance of test

A prostate-specific antigen (PSA) is a substance produced by cells of the prostate gland. The prostate is a small gland that is part of a man’s reproductive system. Men normally have low PSA levels in their blood. A high PSA level may be a sign of prostate cancer, the most common non-skin cancer affecting American men. High PSA levels can also mean noncancerous prostate conditions, such as infection or benign prostatic hyperplasia.

Steps of operation

Clinical application

  • Screen for prostate carcinoma in men over age 50
  • In addition to screening, PSA is measured to evaluate the success of treatment and progression of disease when a known prostate carcinoma is present
  • If the concentration of PSA does not decrease or increases again after surgery, tumor metastasis or recurrence should be considered
