2025年1月31日 · Prostate-specific antigen, or PSA, is a protein produced by normal, as well as malignant, cells of the prostate gland. Both prostate cancer and several benign conditions (particularly benign prostatic hyperplasia, or BPH, and prostatitis) can cause PSA levels in the blood to rise. The PSA test measures the level of PSA in the blood.

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.

Prostate-specific antigen (PSA) is a protein produced by the glandular tissue of the prostate (a walnut-sized gland just below the bladder and in front of the rectum in males). PSA levels can be detected in the blood, urine, or semen. Blood PSA testing is used as a …

Prostate-specific antigen (PSA), also known as gamma-seminoprotein or kallikrein-3 (KLK3), P-30 antigen, is a glycoprotein enzyme encoded in humans by the KLK3 gene. PSA is a member of the kallikrein-related peptidase family and is secreted by the epithelial cells of the prostate gland in men and the paraurethral glands in women. [5]

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.

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.

2023年1月1日 · Prostate-specific antigen (PSA) is a protein produced by prostate cells. The PSA test is done to help screen for and monitor prostate cancer in men. A blood sample is needed. Make sure your health care provider knows all the medicines you are taking. Some drugs cause your PSA level to be falsely low.

2023年8月17日 · The PSA test is a blood test that measures a protein that is produced by normal healthy prostate cells and cancerous prostate cells. PSA levels in the blood are often high among men with prostate cancer, but there’s no clear-cut abnormal or normal PSA level because it can vary from person to person. PSA screening isn’t appropriate for everyone.

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.

2012年3月1日 · Should I have a PSA test? Medical researchers and policymakers need to know whether mass screening programs prevent illness and premature death. In the case of PSA screening, the best available evidence is that testing produces little or no reduction in the risk of dying from prostate cancer.
