Understanding the PSA Test: Purpose, Procedure, and What Results Mean

What Is a 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 blood test to check for prostate problems. For example, it can help find prostate cancer early. The test is also called the prostate-specific antigen test.

Why Is the PSA Test Done?

Doctors may suggest a PSA Test for several reasons. Most often, it is used for prostate cancer screening. However, it can also help check for other prostate issues. Here are some common reasons:

Screening for prostate cancer, especially in men over 50

Checking for prostate problems if you have symptoms like trouble urinating

Monitoring prostate cancer treatment

Watching for cancer return after treatment

According to the CDC, the PSA test can help find prostate cancer early. But, it is not perfect. Sometimes, it finds problems that are not cancer.

How Is the PSA Test Performed?

The PSA blood test is quick and easy. First, a nurse or doctor takes a small blood sample from your arm. Next, the sample goes to a lab. There, experts measure the PSA level. You do not need to stay in the clinic after the test. Most people can go home right away.

What Do PSA Test Results Mean?

PSA test results show the amount of PSA in your blood. Usually, a low PSA level is normal. However, higher PSA levels can mean different things. For example, high PSA can be a sign of:

Prostate cancer

Enlarged prostate (benign prostatic hyperplasia)

Prostate infection (prostatitis)

But, a high PSA does not always mean cancer. Other factors, like age or recent activities, can affect results. Doctors look at your PSA level, age, and health history before making decisions. Sometimes, they may suggest more tests, such as a prostate biopsy.

Risks and Limitations of the PSA Test

While the PSA test is helpful, it has some risks and limits. For instance, it can give false-positive results. This means the test shows a problem when there is none. It can also give false-negative results, missing some cancers. Because of this, not all experts agree on routine PSA screening for everyone. The World Health Organization and CDC suggest talking with your doctor about the risks and benefits.

False positives may lead to stress and more tests

False negatives may miss early cancer

Some prostate cancers grow very slowly and may not cause harm

How to Prepare for a PSA Test

Preparing for a PSA test is simple. Still, there are a few things to keep in mind:

Tell your doctor about any medicines you take

Avoid heavy exercise, like biking, for 48 hours before the test

Do not have sex or ejaculate for 24 hours before the test

Let your doctor know if you have a urinary infection

These steps help make sure your PSA test results are accurate.

Frequently Asked Questions About the PSA Test
