COMPLEXED PSA (cPSA)
Description
- <3.6mg/ml
Clinical significance
- PSA is a glycoprotein produced almost exclusively by the epithelial cells in the prostate. PSA exists in the blood in two forms; free PSA which is not bound to protein and complexed which is bound. Total PSA is the most common test used to detect prostate cancer. However, it has low specificity leading to high levels of false positives and false negatives.
- Prostate tumours typically produce mostly complexed PSA. Benign prostate cells tend to produce more free PSA.
