Prostate specific Ag/Prostate volume calculated from height, width and length

Active

Term Description

For this calculation, the PSA level is divided by the volume of the prostate (using HWL 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.
