PROSTATE SPECIFIC ANTIGEN ( PSA )

Interpretation:  

Elevated levels of PSA are associated with prostate cancer, but may also be seen with prostatitis (Inflammation of the prostate) and benign prostatic hyperplasia (BPH). PSA test done along with free PSA provides additional information. Studies have suggested that the percentage of free PSA in total PSA is lower in patients with prostate cancer than those with benign prostate hyperplasia.
Remark:
PSA may be increased in prostatitis, acute urinary retention, following prostatic massage or DRE.
