What is a PSA test?
The Prostate-Specific Antigen Test or PSA test is a blood test that can help to screen for prostate cancer. PSA is a protein produced by the prostate gland, a small gland in males found below the bladder. Elevated PSA levels can indicate a higher likelihood of prostate cancer. However, other conditions can cause PSA levels to rise so it is important to follow up on results with a doctor. Not all cases of prostate cancer will cause elevated PSA levels so additional testing will be necessary for some people.
Prostate cancer is one of the most common types of cancer and as many as 1 in 8 men will be diagnosed with it in their lifetimes. Identifying prostate cancer early before it spreads is key to successful treatment. In the early stages, prostate cancer often causes no symptoms so routine screenings are important. As it advances, some people will experience symptoms such as trouble urinating, blood in the urine or semen, bone pain, unexplained weight loss, and erectile dysfunction.
What is a normal PSA level?
PSA levels can fluctuate with age and other circumstances. For most men above 50, a PSA below 4.0 is considered normal. It is still recommended to review your PSA test results with your doctor to determine if any follow-up is needed.
What is a dangerous PSA level?
It is important to remember that conditions other than prostate cancer can sometimes cause an elevated PSA level. For most men, a PSA level above 4.0 is considered abnormal. A level above 10.0 indicates a higher risk of prostate cancer. Any elevated results should be discussed with your doctor as a PSA test by itself cannot diagnose or rule out cancer.
When should you take a PSA test?
The PSA test is recommended as a yearly screening for men over the age of 50. Those with a family history of prostate cancer or other risk factors may wish to begin screening earlier. PSA blood testing can also help to monitor treatment for prostate cancer. The Prostate-Specific Antigen Free: Total Ratio which provides more information is also available.
How long does a PSA test take?
Turnaround for the prostate-specific antigen test is typically 1 business day.
