Prostate-Specific Antigen (PSA)

Prostate-specific antigen, also known as gamma-selenoprotein or kallikrein-3, is a glycoprotein enzyme encoded in humans by the KLK3 gene. Psa tumour  marker is a member of the kallikrein-related peptidase family and is secreted by the epithelial cells of the prostate gland.


The PSA test can detect high levels of PSA that may indicate the presence of prostate cancer. However, many other conditions, such as an enlarged or inflamed prostate, can also increase PSA levels. Therefore, determining what a high PSA score means can be complicated.
