Prostate cells produce a substance called Prostate-Specific Antigen (PSA). This substance is only produce by prostate cells. It is usually found in small amounts in the blood of men.
If the result is too high
Certain prostate anomalies, such as prostatitis, benign prostatic hypertrophy and prostate cancer, can cause blood PSA levels to raise.
PSA results can be affected by a recent digital exam or prostate procedure. PSA levels also increase with age. Older patients usually have higher PSA results than younger patients. Furthermore, taking finasteride (Propecia™, Proscar™) will, eventually cause PSA levels to drop.
Before going for blood tests, a procedure or other exam, it is best to always bring a list of all the drugs you take (prescription, OTC and natural health products). Unless told otherwise, you should take your medication as usual on the day of the test. When in doubt, ask your pharmacist for more information.
