Self-testing for prostate-specific antigen (PSA) in whole blood samples
Prostate-specific antigen (PSA) is a protein produced by the epithelial cells of the prostate gland. Its function is to dilute semen and increase sperm motility. It also plays a role in dissolving cervical mucus, allowing sperm to enter the uterus.
Small amounts of PSA are naturally present in the blood of men with good prostate health. However, its levels may rise in the blood as a result of prostate problems, such as prostatitis or benign prostatic hyperplasia. It can also increase naturally with age or after certain medical procedures, such as surgery or diagnostic prostate tests (such as a rectal exam or biopsy).
This test is for:
- Asymptomatic men over the age of 45 who want to have their prostate health checked.
- Men who experience urinary symptoms, such as difficulty urinating, pain, or increased frequency of urination.
