Used to detect PSA. PSA is a protein produced only by the prostate gland. The prostate makes the fluid that nourishes sperm and carries sperm during ejaculation. The amount of PSA produced by the prostate gland can be helpful in detecting prostate cancer. This test is commonly used with the digital rectal exam to screen for prostate cancer. If you have prostate cancer a PSA can be an important tool used to follow the response to treatment for the cancer. In general, serum PSA levels increase due to physical changes to prostate architecture caused by trauma, infection, inflammation, prostate manipulation, benign prostatic hypertrophy (BPH) or malignancy.
Recommended for: Men aged 50 and older should get tested yearly. If you are experiencing symptoms such as painful or frequent urination or have a family history of prostate cancer, it is recommended to get tested earlier.
Estimated turnaround time: 2 days
Additional notes: Recommended to avoid ejaculation 24 hours prior to giving sample as it may cause higher PSA levels. Also, sample should be collected before a digital rectal exam (DRE) and prostate biopsy are performed.< Return to index Testing Services
