Prostate-specific antigen (PSA)

Prostate-specific antigen (PSA) is an intracellular glycoprotein (MW: 34kDa) generated only in the prostate gland. Normal level PSA concentration is 0.1~2.6ng/ml in hman serum. However, the level of PSA concentration can be elevated in the case of prostate affection, for example, benign hyperplasma (enlarged prostate), malignant prostatic tissue, metastatic prostatic carcinoma. So that, many report have suggested that the elevated level of serum PSA is the best marker in the diagnosis of prostate cancers. The Prostate Specific Antigen Rapid Test is a rapid chromatographic immunoassay for the qualitative detection of Prostate Specific Antigen (PSA) in human whole blood, serum or plasma.
