This is called the free to total PSA ratio. Sometimes, if a person has an elevated Total PSA a further test may be ordered that measures two different types of PSA (the amount of PSA bound to protein against the amount of PSA not bound to protein). The initial PSA test usually measures the total PSA in the blood stream. PSA is measured through a simple blood test. However, higher levels of PSA can also be caused by other conditions. As men get older and the prostate gland grows larger, they can often produce higher levels of PSA. PSA is produced by prostate cells and enters the blood stream. It surrounds the urethra, the passage in the penis through which urine and semen pass. The prostate is a walnut-sized gland that sits below the bladder in front of the rectum. ![]() Prostate Specific Antigen (PSA) is a protein made in the prostate gland. False positives and over-diagnosis can cause harm, which means men and their doctors need to carefully consider the pros and cons of testing, based on each man’s age and other individual characteristics.įor men with no family history of prostate cancer and no symptoms, the current guidelines recommend that men who decide to undergo regular testing should be offered PSA testing every two years from age 50 to 69.įor men with a family history of prostate cancer who decide to undergo testing, the guidelines recommend men be offered PSA testing every two years from age 40/45 to 69, with the starting age depending on the strength of their family history. ![]() While PSA testing helps to identify men with an increased risk of undiagnosed prostate cancer, and can help to diagnose prostate cancers earlier, it can also produce false positive results, and in some men picks up cancers that are so slow growing that they do not affect a man’s life expectancy, a finding known as over-diagnosis. Medicare data suggests that up to 21% of Australian men aged 45–74 choose to have a Prostate Specific Antigen (PSA) Test each year, and about 19% of men aged over 74 also undergo testing. ![]()
