Term Description

For this calculation, the PSA level is divided by the volume of the prostate (using PLN volume). Units is ng/ml * cm3.

Part Description

LP18193-0   Prostate specific Ag
Prostate-specific antigen is a glycoprotein and occurs in three forms in the blood: 1) PSA complexed with the serine protease inhibitor or alpha-1-antichymotrypsin, 2) free or uncomplexed PSA, and 3) PSA complexed with alpha-2 macroglobulin. The first two are detectable and the third is undectectable in conventional immunoassay. Elevated levels of PSA in serum or plasma indicate a pathological condition of the prostate (e.g. carcinoma, benign prostatic hyperplasia (BPH), or prostatitis). Inflammation or trauma to the prostate, such as following a biopsy or colonoscopy, can result in PSA elevations. PSA levels are also checked to monitor therapy in patients with prostate cancer.
