Commonly used as a screening test for prostate cancer, the psa test is widely used to detect which men would benefit from a prostate biopsy as well as detect cancer recurrence in men who have been ...Read more

Psa can be used to detect cancers earlier however there is significant controversy regarding the use of this screening modality. Whether to screen should be discussed with your physician. Typically screening is not started in men until they are 50 years old unless they are high risk, then 40. ...Read more

What is the function of prostate-specific antigen in normal males?

A functional protein: It is a glycoprotein made by the cells of the prostate. Psa liquefies/thins out the semen in the seminal glands and allows sperm to swim freely. It is also believed to be instrumental in dissolving the cervical mucus, allowing the entry of sperm into the uterus and up etc....Beyond that, I have no idea what else it does. It is used as tumor marker for prostate cancer monitoring etc..Good luck. ...Read more

Here are...: Largely, the causes for PSA elevation may be categorized as 3 situations, related: with age/prostate size; with infection/inflammation; with cancer occurrence. Each category displays its unique pattern; but of course, multiple factors may be involved. More on PSA/prostate cancer screening? To http://www.formefirst.com/NewAUAPSA.html. ...Read more

Can you please explain the function of prostate-specific antigen in normal cells?

See answer: Prostate specific antigen (psa) is an enzyme which is secreted by the prostate gland and appears to play a role in the liquefaction of semen. Thus it has more of an "exocrine" function vs and endocrine function which imply a role in the physiologic or cellular processes of the body itself. ...Read more

Psa prostatic specific antigen of my father is 1.87 ng/ml is that normal?

Psa  prostatic specific antigen of my father is 1.87 ng/ml is that normal?

Normally 0 to 4: Minor variability among laboratory reference range, but normally between 0-4 is considered normal. But, for some one who had a total prostatectomy (removal of prostate for cancer etc..), any level above 0 is considered abnormal. So, usually 1.8 is normal, but the rate of change is also of some importance. Follow up with doc regularly. Good luck. ...Read more

Is it a problem if my doctor uses psa (protein specific antigen) tests instead of a digital rectal exam for the prostate?

No: Prostate specific antigen (not protein) is a very sensitive marker of prostate function. It very frequently will be elevated before any abnormality is detected by digital rectal exam. However, nothing beats a good clinician being able to feel something on exam. So, really, the two work together to achieve the best results. ...Read more
