See: "PSA, Total" to order monitoring PSA test. PSA measurement used in conjunction with DRE (digital rectal exam) is indicated as an aid for the detection of prostate cancer in men aged 50 years or older, must be identified as PSA for screening. It is also useful in monitoring patients with known prostate cancer. PSA is specific to the prostate gland and is present in normal, hyperplastic and neoplastic prostatic epithelium. Plasma elevations are detected in not only prostate carcinoma, but also in benign prostatic hypertrophy and inflammatory conditions of the prostate and adjacent genitourinary tissues. Diagnosis of prostate cancer requires biopsy and histopathologic examination.
