pros·tate-spe·cif·ic antigen

(prŏs′tāt′spĭ-sĭf′ĭk)
n. Abbr. PSA
A protease secreted by the epithelial cells of the prostate gland. Levels of the protease in blood serum are usually elevated in people with prostate cancer and other conditions such as prostatitis and benign prostatic hyperplasia, and serum level is often used as a screening test for prostate cancer.
