What is the PSA Test?
The PSA test is a simple blood test. It measures the level of prostate-specific antigen (PSA) in your blood. PSA is a protein made by the prostate gland. Doctors often use the PSA test to help find prostate problems, including prostate cancer. Because it is easy to do, many men have heard about the PSA blood test for prostate cancer. However, it is important to know what the test can and cannot tell you.
Why is the PSA Test Done?
Doctors use the PSA test for several reasons. First, it can help find early signs of prostate cancer. Second, it can check for other prostate issues, like an enlarged prostate or infection. In some cases, the test helps monitor men who have already had prostate cancer treatment. For many men, the PSA test is part of routine health checks, especially as they get older.
How is the PSA Test Performed?
Getting a PSA test is quick and simple. First, a healthcare worker draws a small amount of blood from your arm. Next, the blood sample goes to a lab. There, technicians measure the PSA level. You do not need to fast or do anything special before the test. Usually, you can return to your normal activities right after the blood draw.
Understanding PSA Test Results
PSA test results show the amount of PSA in your blood. The results are given in nanograms per milliliter (ng/mL). Most healthy men have PSA levels below 4.0 ng/mL. However, higher levels do not always mean cancer. Many things can raise PSA, such as age, infection, or an enlarged prostate. On the other hand, some men with prostate cancer have normal PSA levels.
Because many factors affect PSA, your doctor will look at your age, health, and family history. Sometimes, they may suggest more tests if your PSA is high.
Risks and Limitations of the PSA Test
While the PSA test can help find prostate problems, it is not perfect. Sometimes, the test gives a false positive. This means the PSA is high, but there is no cancer. Other times, it gives a false negative. This means the PSA is normal, but cancer is present. Because of these limits, the PSA test alone cannot diagnose prostate cancer. You may need more tests, like a biopsy, to know for sure.
According to the CDC, it is important to talk with your doctor about the risks and benefits before having a PSA test.
When Should You Consider a PSA Test?
Not every man needs a PSA test. In the United States, guidelines suggest men talk with their doctor about PSA testing at age 50. However, some men may need to start earlier. For example, if you have a family history of prostate cancer or are African American, you may be at higher risk. In these cases, doctors may suggest starting at age 45 or even 40. Always discuss your personal risk factors with your healthcare provider.
