The AFIAS PSA test is a fluorescent immunoassay (FIA) for the quantitative determination of prostate specific antigen (PSA) in human whole blood, serum or plasma. The test is used as an aid in the screening and treatment of prostate cancer or other prostate diseases. For in vitro diagnostic use only.
Prostate-specific antigen (PSA), a neutral serine protease with chymotrypsin-like activity, consists of a single polypeptide chain of 237 amino acids. It is an intracellular glycoprotein containing 7-8% carbohydrate as a single N-linked oligosaccharide side chain and has a molecular weight of approximately 34,000 Da. PSA is synthesised exclusively by the prostate epithelium and is mainly secreted into the seminal fluid. Normally, very small amounts of PSA are released into the male blood and detected there. It is known that elevated levels of PSA in male blood can be associated with some prostate conditions such as prostatitis, benign prostatic hyperplasia (BPH) or prostate cancer.
