Prostate Specific Antigen (PSA) Test
A blood sample is taken by your doctor to check for prostate specific antigen (PSA), which is produced by the prostate and is increased by cellular abnormalities within the prostate.

As men get older the prostate gland grows and so the PSA is likely to rise. A high PSA may indicate some type of prostate disease. The level can be raised due to inflammation of the prostate (Prostatitis) and enlargement of the prostate gland (Benign Prostatic Hyperplasia or BPH).
