Blood PSA refers to a blood draw for a PSA test, which is primarily an indicator to screen for prostate cancer, but also to diagnose conditions such as benign prostatic hyperplasia and prostatitis.
PSA is a prostate-specific antigen that is secreted by prostate epithelial cells and periurethral tissues. Blood PSA is a PSA test which contains items such as serum PSA concentration, free PSA percentage, and serum PSA rate. This test is mainly used to diagnose prostate cancer in clinical practice and can improve the accuracy of prostate cancer screening. It should be performed regularly for high-risk groups.
In addition, PSA test can also be used to diagnose other prostate diseases, such as benign prostatic hyperplasia and prostatitis. Secondly, it is important to avoid sexual intercourse for 24 hours before the PSA test to prevent ejaculation from increasing the concentration of PSA, which in turn affects the test results.
To summarize, if the patient’s PSA test result is not abnormal, it is enough to have a physical examination on time. If the PSA test result is abnormal, it is necessary to complete other tests to clarify the cause of the disease and cooperate with the doctor for active treatment.
