2024年4月5日 · The prostate-specific antigen (PSA) test is used to measure blood PSA levels and help detect prostate cancer or other prostate abnormalities.

2023年4月27日 · The PSA test is a blood test used primarily to screen for prostate cancer. 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.

2025年1月31日 · The PSA test measures the level of PSA in the blood. This test is used in several different ways: to monitor the progression of prostate cancer in men who have already been diagnosed with the disease; to follow up on prostate symptoms, such as painful or frequent urination, blood in urine or semen, and pelvic and/or back pain

PSA levels can be detected in the blood, urine, or semen. Blood PSA testing is used as a screening test for prostate cancer. Prostate-specific antigen (PSA) levels by age remain the same across most populations. A PSA level above 4.0 ng/mL in any age group must be investigated.

2024年3月21日 · What is a PSA test? A prostate-specific antigen (PSA) test measures the amount of PSA in your body. It’s a type of blood test that reveals if you have elevated PSA levels. PSA is a protein that your prostate gland makes. Normal and cancerous prostate tissue make PSA. But prostate cancer tends to produce PSA in higher amounts.

2024年3月18日 · PSA levels can be measured in the bloodstream, and elevated PSA levels can sometimes be a symptom of prostate cancer. So, this antigen gives doctors a starting point to evaluate your risk of having that disease. But what constitutes a normal PSA level? Why might your PSA levels be elevated?

Prostate-specific antigen (PSA) screening leads to increased prostate cancer diagnoses. Although it is recommended by some clinical practice guidelines, PSA screening remains controversial

Learn how the prostate specific antigen (PSA) blood test can help to diagnose prostate problems, the pros and cons of the test, what the results mean, and what might happen afterwards.

2024年9月10日 · In prostate cancer screening, an elevated serum prostate-specific antigen (PSA) level is the most common initial laboratory finding, as the vast majority of men with early prostate cancer are asymptomatic.

A man should discuss rising PSA test levels with his doctor. Doctors consider a number of factors before recommending further treatment. Additional treatment based on a single PSA test result is often not recommended. Rather, a rising trend in PSA test results over a period of time combined with other findings, such as an abnormal DRE,
