Prostatic Acid Phosphatase

This Prostatic Acid Phosphatase test (prostate cancer screening test) is useful for monitoring of people on therapy for prostate cancer.

The prostate is a small gland in males that helps produce fluid that make up part of semen. It is a common site to get enlargement of the gland or develop cancer. Prostatic acid phosphatase (PAP) is a type of glycoprotein which is produced by the prostate. This glycoprotein can be measured in the blood and aids in the diagnosis and severity of prostate cancer. It is often used along with prostate specific antigen (PSA). While not the best test for screening and diagnosis, it is especially useful for monitoring of people on therapy for prostate cancer.

This prostate cancer screening test is performed in following conditions such as:

• Screening for prostate cancer after age 50
• Men on treatment for prostate cancer
• Difficult, painful, and/or frequent urination
• Back pain
• Pelvic pain
• Difficulty ejaculating
• Suspicious mass on DRE

Also Known As: Male PAP
