PRODUCT NAME:	AccuBind Free Prostate Specific Antigen (fPSA)
INTENDED USE:	The quantitative determination of Free Prostate Specific Antigen (fPSA) concentration in human serum by a Microplate Enzyme Immunoassay.
PRODUCT OVERVIEW:	In human serum, PSA occurs in two forms: free PSA (f-PSA) and total PSA. The major form is a complex of PSA and α-antichymotrypsin (ACT). The fraction of f-PSA was shown to be substantially smaller in patients with untreated advanced prostate cancer (PCA) than in patients with benign prostate hyperplasia (BPH). Therefore combined measurements of f-PSA and t-PSA may lead to a better discrimination between BPH and PCA. Recent studies have shown that the f-PSA/t-PSA ratio is helpful in the differential diagnosis of BPH and PCA.
