The ratio of free prostate-specific antigen (f-PSA) to total PSA (t-PSA) in serum, calculated as percent free PSA (f-PSA%), is lower in patients with prostate carcinoma (PCa) than in patients with benign prostate hyperplasia (BPH). This parameter facilitates discrimination between the 2 groups of pa
The ratio of free to total prostate-specific antigen in serum is correlated to the prostate volume

Background. Prostate specific antigen (PSA) is useful as a tumor marker for monitoring patients with prostate cancer after definitive therapy. Limitations have been noted when PSA was used for the early detection of prostate cancer. The use of prostate specific antigen density [PSAD = PSA (ng/ml)/pr
## BACKGROUND. Human glandular kallikrein (hK2), the prostate specific antigen (PSA) close homologue, possesses approximately 80% structure identity with PSA. The identification of PSA was an important step in the detection of prostate carcinoma (PCa). Thus, hK2 measurement in the serum has the po
