- The PSA test is used for purposes of prostate cancer detection along with a digital rectal exam (DRE). The test should always be given before the digital exam. Touching the prostate may elevate PSA level. Although it is called prostate specific, the antigen measured by this test is not specific for prostate cancer.

- Tests to check for prostate cancer include: A prostate specific antigen (PSA) blood test to help diagnose and manage prostate problems Magnetic resonance imaging (MRI) and computerised tomography (CT), both of which can look at the prostate in detail Biopsy, where a specimen of tissue is taken from the prostate gland.

Why is the PSA test useful and important? The PSA test stands for prostate specific antigen. An antigen is an antibody designed to protect against disease. And because we can test for a prostate specific antigen, the volume of that antigen can indicate the seriousness of any disease that is attacking the prostate.By itself, a PSA reading does not mean very much. The PSA is only a very rough indicator.It certainly does not predict prostate cancer, but it may give you an early indication. However, the PSA is very unreliable and essentially flawed as a test for prostate cancer because a raised PSA can mean many different things.nd because we can test for a prostate specific antigen, the volume of that antigen can indicate the seriousness of any disease that is attacking the prostate.

More than 200,000 men are diagnosed and more than 30,000 men die each year from prostate cancer, making it the most common cancer in men in the U.S. Prostate Specific Antigen (PSA) is a blood test that has been used for more than 20 years to screen for prostate cancer.

The PSA test The PSA test is a blood test that measures the amount of prostate specific antigen (PSA) in your blood. PSA is a protein produced by normal cells in the prostate and also by prostate cancer cells. It’s normal to have a small amount of PSA in your blood, and the amount rises as you get older and your prostate gets bigger.

Prostate cancer screening: Should you get a PSA test? Cancer screening tests — including the prostate-specific antigen (PSA) test to look for signs of prostate cancer — can be a good idea. Prostate cancer screening can help identify cancer early on, when treatment is most effective.ut PSA levels can also be elevated in men with enlarged or inflamed prostate glands. Therefore, determining what a high PSA score means can be complicated. Besides the PSA number itself, your doctor will consider a number of other factors to evaluate your PSA scores: 1  Your age.

PSA Test (Prostate Specific Antigen) Prostate-specific antigen (PSA) test facts. 1  The PSA test is a blood test. 2  The PSA test can be useful for detecting prostate cancer, monitoring its treatment, or assessing its recurrence. 3  The PSA test can also be abnormal with benign enlargement (benign prostatic hyperplasia or BPH), inflammation (prostatitis), and infection of the prostate gland. PSA is a chemical that is produced by both cancerous and noncancerous prostate tissues. Prostate cancer is the third leading cause of death in men.

Prostate-Specific Antigen (PSA) Test Prostate-specific antigen, or PSA, is a protein produced by cells of the prostate gland. The PSA test measures the level of PSA in a man’s 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.The blood level of PSA is often elevated in men with prostate cancer, and the PSA test was originally approved by the FDA in 1986 to monitor the progression of prostate cancer in men who had already been diagnosed with the disease.he results are usually reported as nanograms of PSA per milliliter (ng/mL) of blood.

- Free PSA Test Helps in Prostate Cancer Diagnosis by William J. Catalona, M.D. A relatively new and helpful addition in the diagnosis of prostate cancer is the free PSA Test. This blood test is done in addition to the PSA Test and the finger (digital) examination. The PSA Test measures a protein in the blood that is produced only by the prostate gland. Some of the PSA in blood is bound to other proteins and the rest circulates freely. This free PSA is a damaged variant of PSA that no longer is able to bind to other proteins and thus circulates in the blood in the unbound (free) form.

What is PSA? Prostate-specific antigen (PSA) is a protein produced exclusively by prostate cells. There is a simple blood test to measure your PSA level and this may help to detect early prostate cancer. The chance of having prostate cancer goes up as your PSA level increases (see table below).Small amounts can also be found in the blood of healthy men as doctors have not yet determined what is a ‘normal’ level.ou can use Risk Calculator 2 to assess your risk if you know your PSA level. However, if your PSA is above 3 or 4 ng/ml your doctor may want to do a biopsy. This would involve taking one or more samples from your prostate gland to give them a clearer picture.

Prostate Cancer Treatment and Screening Options The prostate-specific antigen (PSA) test is done to: 1  Screen men for prostate cancer. 2  Since other common medical conditions, such as benign prostatic hyperplasia (BPH) and prostatitis, can cause high PSA levels, a prostate biopsy may be done if your doctor is concerned about signs of prostate cancer. prostate-specific antigen (PSA) test measures the amount of prostate-specific antigen in the blood. PSA is released into a man's blood by his prostate gland.

Prostate Cancer Prostate specific antigen (PSA) blood test: The PSA blood test measures the level of a protein found in the blood that is produced by the prostate gland and helps keep semen in liquid form. The PSA test can indicate an increased likelihood of prostate cancer if the PSA is at an increased or elevated level or has changed significantly over time, but it does not provide a definitive diagnosis.

Tumor Markers Screening is when you test for a disease even if you have no symptoms. Health care providers use the prostate specific antigen (PSA) test and digital rectal examination (DRE), to screen for prostate cancer. They advise both for early detection. There is debate on how often men should have a PSA test. Abnormality in either test is usually not due to cancer, but to other common conditions.

Prostate Specific Antigen (PSA) Prostate specific antigen (PSA) is a protein produced primarily by cells in the prostate, a small gland that encircles the urethra in males and produces a fluid that makes up part of semen. Most of the PSA that the prostate produces is released into this fluid, but small amounts of it are also released into the bloodstream. This test measures the amount of PSA in the blood. The PSA test is used as a tumor marker to screen for and to monitor prostate cancer.
