Prostate Disease Screening
Prostate-specific PSA antigen is produced by the prostate gland in the male reproductive system and can be measured by blood tests. As men with age 40-60 years, prostate size may increases and lead to pressure on the urethra or urethra which is resulted in preventing urinary flow and emptying bladder completely. PSA values also increase with increasing prostate size.
The higher the PSA level, the greater the chance of developing prostate cancer.
Screening helps identify evidence of disease before the onset of clinical symptoms, and PSA testing is one of the cases that it evaluated in screening for prostate problems such as prostate cancer.
An increase in PSA may also be due to the following factors:
- Clinical examination of the patient’s prostate by a physician
- Benign prostatic enlargement
- Infection and inflammation in the urinary tract
- Have sex before the test
Measurement of Prostate Specific Antigen
PSA testing is one of the best non-invasive methods for screening for prostate diseases such as prostate malignancies and is not expensive. Prostate cancer is slow-growing, so detecting this malignancy increases the chance of treating and controlling the side effects of the disease.
The American Urological Association recommends an annual PSA for men over 50. In the case of one of their first-degree relatives who have had prostate cancer at an early age, the test should be performed annually by the age of 40.
Prostate-specific antigen is present in various forms in the blood. Part of PSA in blood is free PSA and part of it in combination with other molecules. Measuring free and total PSA and calculating the ratio of the two as an effective indicator in disease screening is commonly required.
Patient conditions for testing:
The test is performed on a blood sample and does not require fasting.
