Cancer.gov: “Prostate-Specific Antigen (PSA) Test.” The prostate specific antigen (PSA) test is used to measure blood PSA levels and help detect prostate cancer or other prostate abnormalities. Learn more about the PSA blood test at WebMD.

What is a prostate-specific antigen test?

A prostate-specific antigen (PSA) test is a blood test that measures the level of PSA in a sample of your blood. PSA is a protein made by your prostate. The prostate is a gland in the male reproductive system. It lies just below the bladder. It makes the fluid part of semen. It's normal to have a low level of PSA in your blood.

What is a PSA test?

The PSA test is a blood test that measures the amount of prostate specific antigen (PSA) in your blood. It can help to diagnose prostate cancer. Your doctor or nurse takes a sample of your blood. This can be done at your GP practice. They then send this off to a laboratory to check the amount of PSA.

Can a PSA test detect prostate cancer?

The standard PSA test measures the amount of free and bound PSA in the blood. There is no national screening programme for prostate cancer in the UK. This is because previous research showed that the PSA test isn’t a reliable test that can pick up prostate cancer that needs treatment. Research is going on to find a new test.

What is a prostate-specific antigen (PSA) test?

Prostate-specific antigen, or PSA, is a protein produced by normal, as well as malignant, cells of the prostate gland. The PSA test measures the level of PSA in the blood. For this test, a blood sample is sent to a laboratory for analysis. The results are usually reported as nanograms of PSA per milliliter (ng/mL) of blood.

Can a PSA test tell you if you have prostate cancer?

So a PSA test alone can’t usually tell you if you have prostate cancer. It is the first step in deciding if you need more tests. Many men with a raised PSA level don't have prostate cancer. And some men with a normal PSA level do have prostate cancer.

What does a prostate test measure?

The test measures the amount of prostate-specific antigen (PSA) in your blood. PSA is a protein produced by both cancerous and noncancerous tissue in the prostate, a small gland that sits below the bladder in males. PSA is mostly found in semen, which also is produced in the prostate.
